Catalyst 4500 Series Switch Cisco IOS System Message Guide, 12.2(31)SG

Messages and Recovery Procedures

---

This chapter lists and describes the Cisco IOS system error messages by facility for the Catalyst 4500 series switch. Within each facility, the messages are listed by severity levels 0 to 7. The highest severity level is 0, and the lowest severity level is 7. Each message is followed by an explanation and a recommended action, if one is available.

The system sends these error messages to the console (and, optionally, to a logging server on another system). Not all system error messages indicate problems with your system; some messages are purely informational, while other messages help diagnose problems with communication lines, internal hardware, or the system software.

---

Note The messages listed in this chapter do not include the date/time stamp designation; the date/time stamp designation is displayed only if the software is configured for system log messaging.

---

---

Note Writing to a module's serial EEPROM is not standard practice; when the module comes from the factory, the serial EEPROM is set to the correct values. We do not recommend that you change the factory defaults, because this action can cause the module to malfunction.

---

If the explanation that is provided for a given command does not sufficiently explain your problem and no recommended action is given, copy the error message exactly as it appears on the console or in the system log.

You should research and attempt to resolve the error using the Output Interpreter at this URL: https://www.cisco.com/cgi-bin/Support/OutputInterpreter/home.pl.

You can also enter the show tech-support command to gather additional information about the error. If the error message text, information from the Output Interpreter, or output from the show tech-support command do not help you solve the problem, contact your technical support representative and provide the representative with the information that you have gathered. For detailed information on how to contact your technical support  representative, see the "Obtaining Technical Assistance" section on page xiii.

ACL Messages

This section contains the access control list (ACL) message.

Error Message    C4K_ACL-4-OUTOFMEMORY:Out of Memory while allocating [char]

Explanation    The software failed to allocate memory for the given object while processing ACLs. The configuration might have exceeded its maximum limit. If so, the feature using this ACL will not work.

Recommended Action    If it is mandatory that the feature work normally, remove other unwanted features that require ACLs and retry the operation. If the problem persists, contact your technical support representative.

ARP Snooping Messages

This section contains the ARP snooping message.

Error Message    C4K_ARPSNOOPINGMAN-4-OUTOFRESOURCES: Resources for constructing ACLs 
are not available.

Explanation    Software resources are not available to setup hardware to redirect ARP packets to software. Dynamic ARP inspection will not work if this log message appears.

Recommended Action    Unconfigure other TCAM related features to reduce switch memory requirements and reconfigure the ACL.

BUFFERMANAGER Messages

This section contains the memory buffer management (BUFFERMANAGER) message.

Error Message    C4K_BUFFERMANAGER-3-OUTOFVBUFS: Have run out of vbufs (internal 
buffers)

Explanation    The switch ran out of the internal memory buffers that are used for various tasks. This error is unusual because the internal buffers are used for only a short time, released, and then available for reuse. Typically, this condition is transitory.

Recommended Action    If the message persists, reboot the switch.

CHASSIS Messages

This section contains the chassis (CHASSIS) messages.

CHASSIS-2

Error Message    C4K_CHASSIS-2-ALLCHASSISSEEPROMSINVALID: Contents of all chassis's 
serial eeproms are invalid

Explanation    The contents of all of the chassis's serial EEPROMs are invalid. In non-redundant chassis, there is one serial EEPROM, and it is bad. If this is a redundant chassis, there are two serial EEPROMs, and they are both bad.

Recommended Action    Try removing and reinserting the supervisor engine. If that doesn't work, try power cycling the switch. If the serial EEPROM is still invalid, this chassis should be returned.

Error Message    C4K_CHASSIS-2-SUPERVISORSEEPROMINVALID: Contents of supervisor's 
serial eeprom are invalid

Explanation    The contents of the supervisor engine's serial EEPROM are invalid. For example, a bad checksum or the supervisor engine type doesn't match with the other hardware information. This could happen if the read failed because the supervisor engine isn't seated correctly in the slot.

IOS considers this supervisor engine faulty and will not bring up the chassis' interfaces.

Recommended Action    Try removing and reinserting the supervisor engine. If that doesn't work, try power cycling the switch. If the switch still fails to come online, this supervisor engine should be returned.

Error Message    C4K_CHASSIS-2-INLINEPOWEROFF:Inline power to the switch has been 
turned off

Explanation    Software detected that the pass-through current is disabled. This condition will cause all phones drawing PoE from the switch to be powered off.

Recommended Action    If you want PoE, verify that the in-line power switch on the power supply is turned on.

Error Message    C4K_CHASSIS-2-INSUFFICIENTFANSDETECTED:Too few working fans in fan 
tray, the chassis will overheat. If not resolved, in 4 minutes all line cards will 
be placed into Reset-Mode

Explanation    Two or more fans in the system fan tray or power supplies are malfunctioning, or the fan tray has been removed. Although this is a minor alarm, system components could overheat and shut down.

Recommended Action    Replace the system fan tray or broken fans.

Error Message    C4K_CHASSIS-2-INSUFFICIENTFANSSHUTDOWN: Resetting linecards due to fan 
tray failure

Explanation    One or more required fans in the fan tray or the power supplies is malfunctioning. Software reset the modules to reduce heat generation.

Recommended Action    Replace the broken fans as soon as possible.

Error Message    C4K_CHASSIS-2-INSUFFICIENTPOWERDETECTED:Insufficient power available 
for the current chassis configuration

Explanation    The current chassis configuration exceeds power availability. If this condition persists, software will reset the modules.

Recommended Action    If the power availability problem persists and impacts performance, replace the power supply with a larger capacity power supply.

Error Message    C4K_CHASSIS-2-INSUFFICIENTPOWERSHUTDOWN:Holding module in slot [dec] 
in reset, due to insufficient power

Explanation    The switch was using more power than is available for the allowed time interval. Software reset the modules to reduce power consumption.

Recommended Action    If the power availability problem persists and impacts performance, replace the power supply with a power supply with a larger capacity.

Error Message    C4K_CHASSIS-2-OVERHEATINGSHUTDOWN:Resetting linecards due to critical 
temperature

Explanation    The switch is now warmer than its maximum allowable operating temperature. Software will reset modules to reduce heat generation.

Recommended Action    Verify that the switch is in the proper operating environment and that the fans are functioning properly.

CHASSIS-3

Error Message    C4K_CHASSIS-3-BADGBIC:Port [char]: Gbic's seeprom is bad, try 
reinserting: vendor: [char], p/n: [char], s/n: [char]

Explanation    A Gigabit Interface Converter (GBIC) with a serial EEPROM was detected in the port specified in the message. Although the serial EEPROM's contents were readable, the contents are not valid (possibly due to a bad checksum).

The message lists the vendor, part number, and serial number from the GBIC's serial EEPROM. This message appears if the GBIC is not seated correctly.

Recommended Action    Remove and reinsert the GBIC. If this message appears repeatedly, insert the GBIC in another port to verify that it is the GBIC and not the port that is bad. If the GBIC fails in a different port, return the GBIC to your technical support representative for reprogramming. If the GBIC works in the other ports but not in the original port, the original port is bad, and you need to return the module to your technical support representative for repair. To test the port further, insert a different GBIC into the port. If the other GBIC fails in that port, the port is bad.

Error Message    C4K_CHASSIS-3-BADMACRANGEINSPROM:Module [dec]'s serial eeprom 
contains [dec] mac addresses, but needs [dec]

Explanation    The contents of the module's serial EEPROM is incorrect, and the range is smaller than the number of front-panel ports for the module. The module's serial EEPROM contains a range of MAC addresses for this module, and the range should contain the same number of MAC addresses as the number of front-panel ports because each MAC address corresponds to a front-panel port.

Recommended Action    Contact your technical support representative; you will likely have to return the module to Cisco to reprogram the serial EEPROM.

Error Message    C4K_CHASSIS-3-CHASSISTYPEMISMATCHINSPROM: Supervisor's FPGA register 
chassis type is [char], but chassis' serial eeprom chassis type is [char]

Explanation    The chassis type in the supervisor engine's FPGA register doesn't match the type in the chassis' serial EEPROM.

Recommended Action    Check the chassis serial EEPROM information, using the show idprom chassis command. This should never happen in a production chassis. If it does, the chassis needs to be returned.

Error Message    C4K_CHASSIS-3-CLOCKMODULESEEPROMINVALID: Invalid Clock Module seeprom 
data

Explanation    A failure occurred while reading the clock module serial EEPROM. This message should occur only in a prototype switch used in an early field trial.

Recommended Action    Contact your technical support representative. You may need to return some switch components for repair or replacement.

Error Message    C4K_CHASSIS-3-DAUGHTERCARDSEEPROMREADFAILED:Failed to read the serial 
eeprom on module [dec], daughter card [dec]

Explanation    The serial EEPROM for a daughter card on the specified module is unreadable. Because reading this EEPROM is the only way to determine the type of card, the card remains offline, as if it was not installed on the module.

Recommended Action    Remove the module, and then remove and reseat the daughter card in the module. If this message reappears after you reinsert the module into the switch, the serial EEPROM might be bad. Contact your technical support representative; you will likely have to return the module to Cisco to reprogram or replace the serial EEPROM.

Error Message    C4K_CHASSIS-3-FANTRAYSEEPROMINVALID: Invalid fan tray seeprom data

Explanation    A failure occurred while reading the system fan tray serial EEPROM. This message should occur only in a prototype switch used in an early field trial.

Recommended Action    Reseat the fan tray to see if the message is due to a faulty connection. If it persists, contact your technical support representative. You may need to return some switch components for repair or replacement.

Error Message    C4K_CHASSIS-3-FIRSTCHASSISSEEPROMINVALID: Contents of chassis's first 
serial eeprom are invalid

Explanation    The contents of the chassis's first serial EEPROM are invalid. This message only appears in a redundant chassis, which means there is a second serial EEPROM.

Recommended Action    Try power cycling the switch. If the serial EEPROM is still invalid, this chassis should be returned.

Error Message    C4K_CHASSIS-3-GBICSEEPROMREADFAILED:Failed to read gbic serial eeprom 
on port [char], try reinserting

Explanation    A Gigabit Interface Converter (GBIC) was detected in the specified port, but the contents of the GBIC's EEPROM was unreadable. The EEPROM must be read to determine the GBIC type. The read might fail if the GBIC is not seated correctly.

Recommended Action    Remove and reinsert the GBIC. If this message reappears, insert the GBIC in another port to verify that it is the GBIC and not the port that is bad. If the GBIC fails in the other port, return the GBIC to your technical support representative for reprogramming. If the GBIC works in the other ports but not in the original port, the original port is bad, and you need to return the module to your technical support representative for repair. To test the port further, insert a different GBIC into the port. If the other GBIC also fails in that port, the port is bad.

Error Message    C4K_CHASSIS-3-INCOMPATIBLETRANSCEIVERINSERTED: Port [char]: New 
transceiver inserted is incompatible for this module.

Explanation    The inserted transceiver is not compatible with the switching module. The release notes contain a list of supported transceivers for this module.

Recommended Action    Remove this transceiver from the port if it is incompatible with this module. If it is a supported transceiver, it may need to be replaced.

Error Message    C4K_CHASSIS-3-INSUFFICIENTPOWER:Insufficient power to bring up module 
in slot [dec]

Explanation    The module type was identified, but the switch does not have sufficient power to bring the module up. The switch holds the module in reset mode to consume less power.

Recommended Action    Add or replace a power supply to expand the power capacity of the chassis.

Error Message    C4K_CHASSIS-3-INSUFFICIENTPOWERSUPPLIESDETECTED:

Insufficient power supplies present for specified configuration

Explanation    The system software detected that the current chassis configuration has fewer power supplies than required for the existing configuration.

Recommended Action    Add a power supply to meet the needs of the current chassis configuration.

Error Message    C4K_CHASSIS-3-INVALIDMGMTETHERNETADDR: Chassis SPROM not set or 
invalid MAC address range

Explanation    The out of band management port uses a MAC address from the system's MAC address range. The contents of the system's SPROM are bad, so the out of band management port does not have a MAC address.

Recommended Action    Contact your technical support representative. You may need to return some switch components for repair or replacement.

Error Message    C4K_CHASSIS-3-LINECARDMUXBUFFERTOSUPALIGNMENTWRONG:Linecard [dec] 
MuxBuffers aligned towards supervisor in slot [dec] instead of [dec]

Explanation    The mux buffers that work with the switching module in the mentioned slot are configured to work with the standby supervisor engine. The switching module is completely unusable in this condition.

Recommended Action    Try removing and reinserting the affected switching module. If that doesn't work, try resetting the switch. If the problem persists, contact your technical support representative.

Error Message    C4K_CHASSIS-3-MIXINVOLTAGEDETECTED:Power supplies in the chassis are 
receiving different voltage inputs

Explanation    All the inputs to a chassis must be at the same voltage. Mixed voltage inputs are not supported.

Recommended Action    Change the power supplied to the switch so that all inputs to the chassis are of the same type.

Error Message    C4K_CHASSIS-3-MUXBUFFERSEEPROMINVALID: Invalid data in mux buffer 
[dec]'s serial eeprom

Explanation    The mux buffer serial EEPROM could not be read or has not been programmed.This message should occur only in a prototype switch used in an early field trial.

Recommended Action    Reseat the mux buffers to see if the message is due to a faulty connection. If it persists, contact your technical support representative. You may need to return some switch components for repair or replacement.

Error Message    C4K_SUPERVISOR-3-MUXMAYMISALIGN:Linecard Mux-buffers may mis-align to 
incorrect supervisor due to reset with other supervisor desires to be active

Explanation    While resetting the switching modules and taking them out of reset the other supervisor engine is trying to become active using hardware hot-standby logic. This may cause incorrect alignment of the switching module mux-buffers to use the non-active supervisor engine, and the switch will not be able to pass traffic until the alignment is reset.

Recommended Action    Reset the other supervisor engine using the redundancy reload peer command, and contact your technical support representative to report the failure.

Error Message    C4K_CHASSIS-3-LINECARDNOTVALIDINSLOT: Module (Field Replaceable Unit 
minor type [dec]) is not supported in slot [dec]

Explanation    The supervisor engine identified the type, but the switching module cannot be supported in this slot due to the insufficient number of backplane ports in this slot.

Recommended Action    This is an informational message only. No action is required. If possible, move the switching module to another slot, and use a supported module in the original slot.

Error Message    C4K_CHASSIS-3-LINECARDSEEPROMREADFAILED:Failed to read module [dec]'s 
serial eeprom, try reinserting module

Explanation    The switch cannot read the serial EEPROM of the specified module, and the module will not boot because the EEPROM failed to identify the module type. The read might fail if the module is not seated correctly in the slot.

Recommended Action    Remove and reinsert the module. If this message reappears, reboot the switch. If the problem persists, contact your technical support representative. You will likely have to return the module to Cisco to reprogram or replace the serial EEPROM.

Error Message    C4K_CHASSIS-3-LINECARDSEEPROMWRITEFAILED:Failed to write module 
[dec]'s serial eeprom

Explanation    A write operation to the serial EEPROM failed. The write might fail if the module is not seated correctly in the slot.

Recommended Action    Remove and reinsert the module. If this message reappears, reboot the switch. If the problem persists, contact your technical support representative. You will likely have to return the module to Cisco to reprogram or replace the serial EEPROM.

Error Message    C4K_CHASSIS-3-MIXINPOWERDETECTED:Power supplies in the chassis are of 
different types (AC/DC) or wattage

Explanation    The software detected different kinds of power supplies in the chassis. In a Catalyst 4006 chassis, the power values default to the wattage of the weakest power supply. If you mix power supplies in a Catalyst 4500 series chassis, the switch will use the power supply in power supply bay 1 (PS1) and ignore the power supply in power supply bay 2 (PS2). We do not recommend mixing power supplies of different wattages.

Recommended Action    Verify that both power supplies are the same kind and wattage. Replace a power supply if necessary.

Error Message    C4K_CHASSIS-3-MIXINVOLTAGEDETECTED:Power supplies in the chassis are 
receiving different voltage inputs

Explanation    All the inputs to a chassis must be at the same voltage. Mixed voltage inputs are not supported.

Recommended Action    Replace one of the power supplies so that the power supplies used are of the same model.

Error Message    C4K_CHASSIS-3-MODULENOTSUPPORTHALF:Module [dec] does not support 10 Mb 
or 100Mb Half duplex operation. Please have your card upgraded if you need half 
duplex operation.

Explanation    Some preproduction switching modules have interfaces that do not work in half-duplex mode. This module is probably a prototype.

Recommended Action    Contact your technical support representative; you will likely have to return the module to Cisco.

Error Message    C4K_CHASSIS-3-OLDWSX4124: WS-X4124-FX-MT revision [dec].[dec], which 
is < 1.6, is not supported

Explanation    WS-X4124-FX-MT modules with revisions < 1.6 are not supported.

Recommended Action    This module needs to be replaced with a WS-X4124-FX-MT module that has a newer hardware revision number.

Error Message    C4K_CHASSIS-3-ONLYLXSFPSALLOWED:Port [char] has a non-LX SFP, which is 
not supported

Explanation    The WS-X4448-GB-LX module supports only LX SFPs. It marks any other type of Small Form-Factor Pluggable (SFP) as faulty.

Recommended Action    Replace the SFP with an LX SFP that Cisco supports.

Error Message    C4K_CHASSIS-3-OUTOFMEMORY:Ran out of memory - cannot allocate internal 
buffers

Explanation    The switch ran out of memory in the temporary buffers.

Recommended Action    If this message reappears, reboot the switch.

Error Message    C4K_CHASSIS-3-POWERSUPPLYSEEPROMINVALID: Invalid data in power supply 
[dec]'s serial eeprom

Explanation    The power supply serial EEPROM could not be read or has not been programmed.

Recommended Action    Try re-inserting the power supply. If that doesn't work, replace it with a new power supply.

Error Message    C4K_CHASSIS-3-SEEPROMREADFAILEDAFTERWRITE:Error reading back module 
[dec]s serial EEPROM data after write

Explanation    After writing a module's serial EEPROM in response to a CLI request, the switch tried to read it back in, to ensure that the correct values were written out. What the switch read back in differs from what the switch wrote out. The read or write might fail if the module is not seated correctly in the slot.

Recommended Action    Remove and reinsert the module. If that does not work, reboot the switch. If the problem persists, contact your technical support representative. You will likely have to return the module to Cisco to reprogram or replace the serial EEPROM.

---

Note Writing the module's serial EEPROM is not standard practice; when the module comes from the factory, its serial EEPROM is set to the correct values. We do not recommend that you change the factory defaults, because this action could cause the module to malfunction.

---

Error Message    C4K_CHASSIS-3-SFPCRCINTEGRITYCHECKFAILED:SFP integrity check on port 
[char] failed: bad crc

Explanation    The checksum of the SFP SEEPROM is not valid, indicating a bad or non-Cisco SFP.Only Cisco-qualified Small Form-factor Pluggables (SFPs) are supported. Other SFPs place the associated port in a faulty status.

Recommended Action    Replace the SFP with an SFP that Cisco supports.

Error Message    C4K_CHASSIS-3-SFPINTEGRITYCHECKFAILED:SFP integrity check on port 
[char] failed: bad key

Explanation    Only Cisco-qualified Small Form-factor Pluggables (SFPs) are supported. Other SFPs place the associated port in a faulty status.

Recommended Action    Replace the SFP with an SFP that Cisco supports.

Error Message    C4K_CHASSIS-3-SFPSERIALINTEGRITYCHECKFAILED:SFPs on ports [char] and 
[char] have duplicate serial numbers

Explanation    Only Cisco-qualified Small Form-factor Pluggables (SFPs) are supported. Other SFPs place the associated port in the faulty status.

All SFPs must have a unique serial number. If this message appears you likely have a cloned SFP SEEPROM.

Recommended Action    Replace the SFP with an SFP that Cisco supports.

Error Message    C4K_CHASSIS-3-STUBPHYMISMATCH: Stub type mismatch: stub [dec]/[dec] is 
type [dec], should be type [dec]

Explanation    The stubs have non-matching physical types for the specified module.

Recommended Action    Verify that the physical types for every stub on the module match.

Error Message    C4K_CHASSIS-3-SUPERVISORTYPEMISMATCHINSPROM: Supervisor's FPGA 
register type is [dec], but supervisor's serial eeprom type is [dec]

Explanation    The type in the supervisor engine's FPGA register doesn't match the type in the supervisor engine's serial EEPROM. This might happen if the IDPROM is misprogrammed or the supervisor engine's FPGA register somehow returns an incorrect value. Both are extremely unlikely.

Recommended Action    Check the FruMinorType field in the supervisor engine's serial EEPROM, using the show idprom supervisor command. The output should be the same as the number printed in this log message for the FPGA register type. This should never happen with a production supervisor engine. If it does, replace the supervisor engine.

Error Message    C4K_CHASSIS-3-TEMPERATURESENSORREADFAILED: Failed to read the 
supervisor temperature sensor

Explanation    The temperature sensor on the supervisor engine cannot be read. If the chassis becomes overheated, this condition will not be reported.

Recommended Action    Check the switch configuration file to find the source of these packets on the specified port and take corrective action to fix them at the source end. You can also enable port security on that interface to shutdown the port if the incoming rate of packets with invalid source mac address is too high by issuing the switchport port-security limit rate invalid-source-mac <rate> command.

Error Message    C4K_L2MAN-7-ROUTERMACADDRESSRXASSOURCE: Packet received with my own 
MAC address ( [mac-addr]  ) as source on port [char]   in vlan  [dec]

Explanation    A packet was received with the switch's MAC address as the source address. This MAC was not learned as a valid source address, which suggests that there is a configuration problem. This message is rate-limited and is displayed only for the first such packet received on any interface or VLAN. Subsequent messages will display a cumulative count of all such packets received in a given interval on all interfaces in any VLAN. This usually signifies a loop in your configuration. This problem can occur in three conditions; L1 loop, L2 loop, or a host with a bogus MAC address is connected to the switch.

Recommended Action    For L1 loop, verify that the physical connection on the port appears in the syslog message to see if there is a loopback connection. Also use the show cdp neighbor command to see if the switch is seeing itself.

For L2 loop, first use the show spanning-tree interface <intf> command to make sure spanning tree is running for that port. Then use the show spanning-tree vlan <vlan-id> command to make sure the VLAN appears in the syslog on all related switches and confirm that the reported information (including Bridge ID, blocking ports, port priority, etc) is correct across all the switches in the topology. If the STP protocol appears to be working, then capture traffic on the blocking ports to see if it sends traffic. If yes, please contact your technical support representative.

For the third case, determine whether the connected host has its MAC address manually configured to the value of the switch which shows the syslog message.

Explanation    When a replicated packet is sent to the software by an output ACL, the hardware does not indicate whether the packet needs to be bridged or routed.

When resources are exhausted or when the ACLs that are programmed in the hardware cannot handle processing directly (such as ACLs matching TCP flags), the supervisor engine sends the packets to the software for processing. If the software cannot determine whether to bridge or route, the packet might be dropped. This drop indicates that the packet was directed to a Hot Standby Routing Protocol (HSRP) router group MAC address.

Recommended Action    This is an informational message only. No action is required.

Error Message    C4K_PKTPROCESSING-4-UNKNOWNSOURCELOCATIONFORBRIDGE:Unable to 
determine source host location of replicated software-processed packet with source 
address  [mac-addr]  and destination address  [mac-addr] 

Explanation    When a replicated packet is sent by an output ACL to the software for processing, the hardware does not indicate the ingress port or VLAN ID.

When resources are exhausted or when the ACLs that are programmed in the hardware cannot handle processing directly (such as ACLs matching TCP flags), the supervisor engine sends the packets to software for processing. Without the ingress port identifier, the supervisor engine might forward the packet back out the port on which it was received, possibly creating network loops or other problems. If the switch is unable to recognize the ingress port from other information, the packet is dropped.

Recommended Action    This is an informational message only. No action is required.

PKTPROCESSING-5

Error Message    C4K_PKTPROCESSING-5-NOTAPPLYINGACL:Not applying [input/output] Acl 
for packet [packet-info] 

Explanation    The software is unable to determine the correct ACL entry that is indicated by the hardware. The hardware-provided index of the ACL content-addressable memory (CAM) indicates that the software needs to take the actions for the entry at that index. If the packet was queued in the hardware before the software could process it, the index is out of date.

Recommended Action    This is an informational message only. No action is required.

PKTPROCESSING-7

Error Message    C4K_PKTPROCESSING-7-ADJLOOKUPFAILED:Draining the backed up packets in 
CPU queue when we cleaned up FIB adjacencies. Last drained packet's source address  
[ip-addr]  and destination address  [ip-addr]

Explanation    This event can occur when the software processes the routed packets and the router port is shut down. The software can automatically repair adjacencies, but there was at least one packet in the queue that was lost.

SPANTREE Messages

This section contains the Spanning Tree Protocol (SPANTREE) messages.

SPANTREE-2

Error Message    SPANTREE-2-PVSTSIM_OK: PVST Simulation inconsistency cleared on port 
[char].

Explanation    The listed interface is no longer receiving PVST BPDUs advertising information inconsistent with the CIST port information. The PVST simulation inconsistency is cleared and the interface returns to normal operation.

Recommended Action    This is an informational message only. No action is required.

Error Message    

Error Message    SPANTREE-2-BLOCK_BPDUGUARD:Received BPDU on port [char] with BPDU 
Guard enabled. Disabling port.

Explanation    A BPDU was received in the specified interface that has the spanning tree BPDU guard feature enabled. As a result, the interface was administratively shut down.

Recommended Action    Remove the device sending BPDUs, or disable the BPDU guard feature. BPDU guard can be locally configured on the interface or globally configured on all ports that have PortFast enabled. After you resolve the conflict, reenable the interface by entering the no shutdown command in interface configuration mode.

Error Message    SPANTREE-2-BLOCK_PVID_LOCAL: Blocking [char] on [char]. Inconsistent 
local vlan.

Explanation    The spanning tree port that is associated with the listed spanning tree instance [char] and interface [char] is held in spanning tree blocking state until the port VLAN ID (PVID) inconsistency is resolved. The listed spanning tree instance is that of the native VLAN ID of the listed interface.

Recommended Action    Verify that the configuration of the native VLAN ID is consistent on the interfaces at each end of the 802.1Q trunk connection. When the configuration is consistent, spanning tree automatically unblocks the interfaces.

Error Message    SPANTREE-2-BLOCK_PVID_PEER: Blocking [char] on [char]. Inconsistent 
peer vlan.

Explanation    The spanning tree port (with spanning-tree port ID [char]) that is associated with the listed instance and interface is held in blocking state until the port VLAN ID (PVID) inconsistency is resolved. The listed spanning tree instance is that of the native VLAN ID of the interface on the peer switch to which the listed interface is connected.

Recommended Action    Verify that the configuration of the native VLAN ID is consistent on the interfaces on each end of the 802.1Q trunk connection. When corrected, spanning tree automatically unblocks the interfaces.

Error Message    SPANTREE-2-CHNL_MISCFG:Detected loop due to etherchannel 
misconfiguration of [chars] [chars]

Explanation    A misconfigured channel group (with channel group ID [chars]) was detected. For example, the ports of one side of the EtherChannel either are not configured to be in the channel or failed to bundle, while ports on the other side of the EtherChannel are successfully bundled.

Recommended Action    Locate the misconfigured local ports by entering the show interfaces status err-disabled command. Check the EtherChannel configuration on the remote device by entering the show etherchannel summary command on the remote device. After the configuration is corrected, enter the shutdown/no shutdown command on the associated port-channel interface.

Error Message    SPANTREE-2-LOOPGUARD_BLOCK: Loop guard blocking port [char] on [char].

Explanation    The spanning tree message age timer expired, because no BPDUs were received from the designated bridge. Because this condition could be caused by an unidirectional link failure, the interface is put into blocking state and marked as loop guard inconsistent in order to prevent possible loops from being created.

Recommended Action    Use the show spanning-tree inconsistentports command to review the list of interfaces with loop guard inconsistencies. Determine why devices that are connected to the listed ports are not sending BPDUs. One reason could be that they do not run the Spanning Tree Protocol; in this case, you should disable loop guard in the inconsistent interfaces or start the Spanning Tree Protocol on the other side of the links, depending on the context. Another reason could be a failure in the cable. If the link has a failure that makes it unidirectional (you can transmit, but you cannot receive), you should replace the old cable with a new cable.

Error Message    SPANTREE-2-LOOPGUARD_CONFIG_CHANGE: Loop guard [char] on port [char].

Explanation    There was a change in the spanning tree loop guard configuration for the listed interface. When enabled, the interface will be put into blocking state and marked as loop guard inconsistent when the message age timer expires because no BPDUs were received from the designated bridge. This feature is used to detect unidirectional links.

Recommended Action    Verify that this is the desired configuration for the listed interface. Correct it if this is not the desired configuration; otherwise, no further action is required.

Error Message    SPANTREE-2-LOOPGUARD_UNBLOCK: Loop guard unblocking port [char] on 
[char].

Explanation    The listed interface received a BPDU, and if the inconsistency was due to an unidirectional link failure, the problem does not exist anymore. The loop guard inconsistency is cleared for the interface, which is taken out of the blocking state.

Recommended Action    This is an informational message only. No action is required.

Error Message    SPANTREE-2-PVSTSIM_FAIL: Blocking [char] port [char]: Inconsitent 
[char] PVST BPDU received on VLAN [dec]

Explanation    When a PVST+ switch is connected to an MST switch, the CIST (MSTOO) becomes the root for all PVST+ spanning trees. Looping occurs if any PVST+ spanning tree has a root with a better preference than IST. To prevent looping, the port, which is on the MST switch that receives the superior message from the PVST+ side, is blocked by root guard.

When STP is converging after a new switch or a switch port is added to the topology, this condition occurs transiently. The port unblocks automatically in such cases.

Recommended Action    If the port remains blocked, identify the root bridge as reported in the message, and configure a worse priority for the VLAN spanning tree. There could be better PVST roots than the message indicates, and the port will not recover until all such roots are cleared. If you are unsure whether the roots are cleared, disable and enable the port again.

Error Message    SPANTREE-2-RECV_1Q_NON_1QTRUNK: Received 802.1Q BPDU on non 802.1Q 
trunk [char] [char].

Explanation    A Shared Spanning Tree Protocol (SSTP) bridge protocol data unit (BPDU) was received on the listed interface. The interface was in trunk mode but was not using 802.1Q encapsulation. The interface ID is [char].

Recommended Action    Verify that the configuration and operational state of the listed interface and the interface to which it is connected are in the same mode (access or trunk). If the mode is trunk, verify that both interfaces have the same encapsulation (ISL or 802.1Q). Once these parameters are consistent, spanning tree automatically unblocks the interface.

Error Message    SPANTREE-2-RECV_BAD_TLV:Received SSTP BPDU with bad TLV on 
[char][char].

Explanation    The listed interface received an SSTP BPDU that was missing the VLAN ID tag. The BPDU is discarded. [char] is the interface ID.

Recommended Action    If the error message reappears, copy the message exactly as it appears on the console or in the system log, contact your technical support representative, and provide the representative with the gathered information.

Error Message    SPANTREE-2-RECV_PVID_ERR: Received BPDU with inconsistent peer vlan id 
[dec] on [char] [char]

Explanation    The listed interface received an SSTP BPDU that is tagged with a VLAN ID that does not match the VLAN ID on which the BPDU was received. This condition occurs when the native VLAN is not consistently configured on both ends of an 802.1Q trunk. [dec] is the VLAN ID. The interface ID is [char].

Recommended Action    Verify that the configuration of the native VLAN ID is consistent on the interfaces on each end of the 802.1Q trunk connection. Once the configuration is consistent, spanning tree automatically unblocks the interfaces.

Error Message    SPANTREE-2-ROOTGUARD_BLOCK: Root guard blocking port [char] on [char].

Explanation    A BPDU was received on the listed interface that advertised a spanning tree root bridge that was superior to the one already in use. The interface is put into a blocking state and marked as root guard inconsistent to prevent a suboptimal spanning tree topology from forming.

Recommended Action    Enter the show spanning-tree inconsistentports command to review the list of interfaces with root guard inconsistencies. Determine why devices that are connected to the listed ports are sending BPDUs with a superior root bridge, and then take action to prevent further occurrences. Once the invalid BPDUs have been stopped, the interfaces automatically recover and resume normal operation. By looking at the configuration, ensure that it is appropriate to enable root guard on the interface.

Error Message    SPANTREE-2-ROOTGUARD_CONFIG_CHANGE: Root guard [char] on port [char].

Explanation    There was a change in the spanning tree root guard configuration for the listed interface. If root guard is enabled, any BPDU that is received on the interface that advertises a superior spanning tree root bridge to the one that is already in use will cause the interface to be put into blocking state and marked as root guard inconsistent.

Recommended Action    Verify that this is the correct configuration for the listed interface. If this is not the correct configuration, change the configuration to one that is appropriate for the interface.

Error Message    SPANTREE-2-ROOTGUARD_UNBLOCK:Root guard unblocking port [char] on 
[char].

Explanation    The listed interface is no longer receiving BPDUs that are advertising a superior root bridge. The root guard inconsistency is cleared for the interface and then is taken out of the blocking state if appropriate.

Recommended Action    This is an informational message only. No action is required.

Error Message    SPANTREE-2-UNBLOCK_CONSIST_PORT: Unblocking [char] on [char]. Port 
consistency restored.

Explanation    The port VLAN ID and/or port type inconsistencies have been resolved. The Spanning Tree Protocol will unblock the listed interface of the spanning tree instance. The interface ID is [char].

Recommended Action    This is an informational message only. No action is required.

SPANTREE-3

Error Message    SPANTREE-3-BAD_PORTNUM_SIZE:Rejected an attempt to set the port number 
field size to [dec] bits (valid range is [dec] to [dec] bits).

Explanation    The spanning tree port identifier is a 16-bit field that is, by default, divided evenly between the port priority and the port number. Each subfield is 8 bits wide, allowing the port number field to represent port numbers between 1 and 255. On systems with more than 255 ports, the STP subsystem must increase the size of the port number portion of the port ID to support the greater number of ports. This condition occurs at system initialization because the maximum number of ports on a particular platform will not change. This error occurs because of an error in the platform-specific code that caused it to request more (or fewer) bits than were possible.

Recommended Action    Contact your technical support representative.

Error Message    SPANTREE-3-PORT_SELF_LOOPED: [char] disabled.- received BPDU src mac 
([mac-addr])  same as that of interface

Explanation    A BPDU with a source MAC address that matches the address assigned to the listed interface was received. A port looped back on itself, possibly due to a diagnostic cable that was plugged into the interface. The interface is administratively shut down. [char] is the interface ID.

Recommended Action    Check the interface configuration and any cable that is plugged into the interface. Once the problem is resolved, reenable the interface by entering the no shutdown command on the interface.

Error Message    SPANTREE-3-PRESTD_NEIGH: pre-standard MST interaction not configured 
([char]). Please

Explanation    The switch has received a pre-standard MST BPDU transmission on a port that is not configured for it. The switch will automatically adjust its mode of operation on this port and will start sending pre-standard BPDUs. However, this auto-detection of pre-standard neighbors is not 100% accurate, and it is recommended to explicitly configure the port for pre-standard MST BPDU transmission. This warning message is displayed only once.

Recommended Action    Use the spanning-tree mst pre-standard configuration command on all ports that are connected to switches running Cisco's pre-standard version of MST. Migrate all switches in the network to the IEEE standard MST version when it is possible.

SPANTREE-4

Error Message    SPANTREE-4-PORT_NOT_FORWARDING: [char] [char] [char] [char] 

Explanation    The specified interface is not in the forwarding state and forwarding packets.

Recommended Action    Contact your technical support representative.

SPANTREE-5

Error Message    SPANTREE-5-EXTENDED_SYSID:Extended SysId [char] for type [char]

Explanation    The extended system ID feature was either enabled or disabled for the given type of spanning tree. If the feature was enabled, the spanning tree instance identifier is stored in the lower portion of the bridge ID priority field; this will cause the allowed values for the bridge priority to be limited to the range of 0 to 61,440, in increments of 4096. If the feature was disabled, the bridge ID priority field consists entirely of the configured priority, but some spanning tree features might not be available on a given platform (for example, 4096 VLAN support).

Recommended Action    This is an informational message only. No action is required.

Error Message    SPANTREE-5-ROOTCHANGE: Root Changed for [char] [dec]:  New Root Port 
is [char]. New Root Mac Address is [mac-addr]

Explanation    The root changed for an instance of spanning tree.

Recommended Action    This is an informational message only. No action is required.

to [char]

Explanation    The spanning tree port changed to another state.

Recommended Action    This is an informational message only. No action is required.

SPANTREE-7

Error Message    SPANTREE-7-BLOCK_PORT_TYPE: Blocking [char] on [char]. Inconsistent 
port type.

Explanation    The listed interface is being held in spanning tree blocking state until the port type inconsistency is resolved. The port ID is [char].

Recommended Action    Verify that the configuration and operational state of the listed interface and that of the interface to which it is connected are in the same mode (access or trunk). If the mode is trunk, verify that both interfaces have the same encapsulation type (ISL or 802.1Q). When these parameters are consistent, spanning tree automatically unblocks the interface.

Error Message    SPANTREE-7-RECV_1Q_NON_TRUNK: Received 802.1Q BPDU on non trunk [char] 
[char].

Explanation    An SSTP BPDU was received on the listed interface, which is not an operational trunking interface. The interface ID is [char].

Recommended Action    Verify that the configuration and operational state of the listed interface and that of the interface to which it is connected are in the same mode (access or trunk). If the mode is trunk, verify that both interfaces have the same encapsulation type (none, ISL, or 802.1Q). Once these parameters are consistent, spanning tree automatically unblocks the interface.

Error Message    SPANTREE-7-PORTDEL_SUCCESS: [char] deleted from Vlan [dec]

Explanation    The interface was deleted from the specified VLAN.

Recommended Action    This is an informational message only. No action is required.
