Cisco IOS Software Packaging
The Enterprise Services image supports all Cisco Catalyst 4500 Series software features based on Cisco IOS Software, including enhanced routing.
The IP Base image supports Open Shortest Path First (OSPF) for Routed Access, Enhanced Interior Gateway Routing Protocol (EIGRP) "limited" Stub Routing, Nonstop Forwarding/Stateful Switchover (NSF/SSO), and RIPv1/v2. The IP Base image does not support enhanced routing features such as BGP, Intermediate System-to-Intermediate System (IS-IS), Internetwork Packet Exchange (IPX), AppleTalk, Virtual Routing Forwarding (VRF-lite), GLBP, and policy-based routing (PBR).
The LAN Base image complements the existing IP Base and Enterprise Services images. It is focused on customer access and Layer 2 requirements and therefore many of the IP Base features are not required. The IP upgrade image is available if at a later date you require some of those features.
Cisco IOS XE Release Strategy

Cisco IOS XE to Cisco IOS Version Number Mapping
As Table 8 shows, each version of Cisco IOS XE has an associated Cisco IOS version:
Limitations and Restrictions
These sections list the limitations and restrictions for the current release of Cisco IOS software on the Catalyst 4500E series switch.
- For the 10-slot chassis, (C4510R+E), slot 10 can only support 47xx linecards; older 46xx are not supported.
- Starting with Release IOS XE 3.3.0SG, the seven RP restriction was removed.
- More than 16K QoS policies can be configured in software. Only the first 16K are installed in hardware.
- Adjacency learning (through ARP response frames) is restricted to roughly 1000 new adjacencies per second, depending on CPU utilization. This should only impact large networks on the first bootup. After adjacencies are learned they are installed in hardware.
- Multicast fastdrop entries are not created when RPF failure occurs with IPv6 multicast traffic. In a topology where reverse path check failure occurs with IPv6 multicast, this may cause high CPU utilization on the switch.
- The SNMP ceImageFeature object returns a similar feature list for all the three license levels (LAN Base, IP Base, and EntServices). Although the activated feature set for a universal image varies based on the installed feature license, the value displayed by this object is fixed and is not based on the feature license level.
- Standard TFTP implementation limits the maximum size of a file that can be transferred to 32 MB. If ROMMON is used to boot an IOS image that is larger than 32 MB, the TFTP transfer fails at the 65,xxx datagram.
TFTP numbers its datagrams with a 16 bit field, resulting in a maximum of 65,536 datagrams. Because each TFTP datagram is 512 bytes long, the maximum transferable file is 65536 x 512 = 32 MB. If both the TFTP client (ROMMON) and the TFTP server support block number wraparound, no size limitation exists.
Cisco has modified the TFTP client to support block number wraparound. So, if you encounter a transfer failure, use a TFTP server that supports TFTP block number wraparound. Because most implementations of TFTP support block number wraparound, updating the TFTP daemon should fix the issue.
The outputs of certain commands, such as show ip route and show access-lists, contain non-deterministic text. While the output is easily understood, the output text does not contain strings that are consistently output. A general purpose specification file entry is unable to parse all possible output.
While a general purpose specification file entry may not be possible, a specification file entry might be created that returns the desired text by searching for text that is guaranteed to be in the output. If a string is guaranteed to be in the output, it can be used for parsing.
For example, the output of the show ip access-lists SecWiz_Gi3_17_out_ip command is this:
The first line is easily parsed because access list is guaranteed to be in the output:
The remaining lines all contain the term host. As a result, the specification file may report the desired values by specifying that string. For example, this line
will produce the following for the first and second rules
and the following for the third statement
Request the output of the show running-config command using NETCONF and parse that output for the desired strings. This is useful when the desired lines contain nothing in common. For example, the rules in this access list do not contain a common string and the order (three permits, then a deny, then another permit), prevent the spec file entry from using permit as a search string, as in the following example:
The XML output of show running-config command includes the following, which can then be parsed programmatically, as desired:
- When attaching a existing policy-map (that is already applied to a control-port) to another front-panel port, the following message displays:
Workaround: Define a policy-map with a different name and then reattach. CSCti26172
- If the number of unique FNF monitors attached to target exceeds 2048 (one per target), a switch responds slowly:
– Decrease the number of monitors.
– Attach the same monitor to multiple targets. CSCti43798
- ciscoFlashPartitionFileCount object returns an incorrect file count for bootflash:, usb0:, slot0:, slaveslot0:, slavebootflash:, and slaveusb0:.
Workaround: Use the dir device command (for example, dir bootflash:) to obtain the correct file count. CSCti74130
- If multicast is configured and you make changes to the configuration, Traceback and CPUHOG messages are displayed if the following conditions exist:
– At least 10K groups and roughly 20K mroutes exist.
– IGMP joins with source traffic transit to all the multicast groups.
This is caused by the large number of updates generating SPI messages that must be processed by the CPU to ensure that the platform is updated with the changes in all the entries.
- When attaching a existing policy-map (that is already applied to a control-port) to another front-panel port, following message displays:
Workaround: Define a policy-map with a different name and then reattach. CSCti26172
- With traffic running, entering clear ip mroute * with larger number of mroutes and over 6 OIFs will cause Malloc Fail messages to display.
You cannot clear a large number of mroutes at one time when traffic is still running.
Workaround: Do not clear all mroutes at once.
- Although you can configure subsecond PIM query intervals on Catalyst 4500 platforms, such an action represents a compromise between convergence (reaction time) and a number of other factors (number of mroutes, base line of CPU utilization, CPU speed, processing overhead per 1 m-route, etc.). You must account for those factors when configuring subsecond PIM timers. We recommend that you set the PIM query interval to a minimum of 2 seconds. By adjusting the available parameters, you can achieve flawless operation; that is, a top number of multicast routes per given convergence time on a specific setup.
- With Cisco IOS Release XE 3.2.1SG, memory configuration is enabled:
This configuration had been removed erroneously in a prior release.
Workaround: Use the show version command. CSCtr30294
Workaround: Select an alternate destination or source port. CSCty05405
- When sup1 is in ROMMON and sup2 is in IOS, only sup2 can read the SEEPROM contents of the following chassis components:
– mux-buffer for each linecard slot
On sup1, when the sprom read.. command is entered for any of the above components, the SEEPROM contents are displayed as all “0”s.
When sup1 and sup2 are both in ROMMON (or both in IOS (SSO state)), they can read all SEEPROMs.
– 10/100/1000BaseT Premium POE E Series WS-X4648-RJ45V+E (JAE1348OY52)
the following restrictions apply:
– Sub-interfaces are not supported.
– Port-channel members do not support multiple classification criteria for a QoS policy.
– CEF is disabled automatically when uRFP is enabled and TCAM is fully utilized.
- While configuring an IPv6 access-list, if you specify "hardware statistics" as the first statement in v6 access-list mode (i.e. before issuing any other v6 ACE statement), it will not take effect. Similarly, your "hardware statistics" configuration will be missing from the output of the show running command.
Workaround: During IPv6 access-list configuration, configure at least one IPv6 ACE before the "hardware statistics" statement. CSCuc53234
- With IOS Release XE 3.3.0X0, ROMMON supports the Fa1 management interface at 10/100/1000Mbps full duplex mode only; 10/100/1000Mbps half-duplex is not supported. This prevents the FA1 management interface from operating when connected to a half-duplex hub.
- Supervisor Engine 8-E does not support USB port.
- Memory allocation failures can occur if more than 16K IPv6 multicast snooping entries are present.
These messages are cosmetic only, and no ssh services are available unless configured within IOS.
Caveats
Caveats describe unexpected behavior in Cisco IOS releases. Caveats listed as open in a prior release are carried forward to the next release as either open or resolved.
Note For the latest information on PSIRTS, refer to the Security Advisories on CCO at the following URL:
http://www.cisco.com/en/US/products/products_security_advisories_listing.html
Open Caveats for Cisco IOS XE Release 3.3.2XO
This section lists the open caveats for Cisco IOS XE Release 3.3.2XO:
- When more than one Equal Cost Multipath (ECMP) is available on the downstream switch, and Mediatrace is invoked to provide flow statistics, the dynamic policy does not show statistics for a flow.
Mediatrace cannot find the correct inbound interface and applies the dynamic policy on a different interface from the one used for media flow.
- When you enable both Cisco TrustSec and RADIUS accounting, a disparity occurs between the RADIUS client (Cisco switch) and the RADIUS/CTS server in how the authenticator field in the header is computed for DOT1X/RADIUS accounting messages.
A Cisco IOS AAA client uses the PAC secret to compute the authenticator; Cisco Secure ACS 5.2 uses the shared secret. This behavior causes a mismatch that results in a rejection of the accounting message, and the client marks the server as unresponsive.
Workaround: None. You must disable 802.1X accounting. CSCts26844
- A device in a guest VLAN that is connected behind a phone that is capable of 2nd-port-notification experiences packet loss following a SSO failover. The device experiences an authentication restart after the first CDP frame arrives from the phone.
- When you add a "bfd" suffix to the snmp server host x.x.x.x configuration command, the BFD traps, ciscoBfdSessUp and ciscoBfdSessDown, are not generated.
Workaround: Do not specify a "bfd" suffix with the snmp-server host x.x.x.x configuration command. CSCtx51561
- IPv6 access-list counters do not increment when a policy-map associated with a class-map that matches a v6 ACL is applied to a physical interface and matching traffic is sent.
- If you configure a Qos srTCM policer with actions (traffic conform, traffic exceed, and traffic violated), the marking action for exceed traffic remains inactive.
Workaround: Configure a policer with only conform-action and exceed-action and not with violate-action. CSCug49778.
This error is informational only.
- The match application name and collect application name commands appear available for flow record configuration when you use the ? help listings. However, the following configuration is otherwise unsupported: show flow monitor i monitor-name i cache displays the application name as “unknown;” and the application table is not exported. So, the application name field cannot be decoded when exported.
Workaround: Do not configure the application name field as a key or non-key field of a flow record.
Workaround: Use PEAP-GTC or any other method. CSCud66899
- Immediately following an SSO, the following error message may be logged by the new active route processor:
The error message is information only.
- During either a system- or user-initiated reload operation, the following message is observed when the system shuts down:
This message is not observed during a system bootup.
Workaround: None required. This message is information only. CSCtz15738
- When a switchover is created on the Mediatrace responder, the dynamic access list created for a monitored flow tuple is not deleted. Although the Mediatrace initiator creates another set of dynamic access lists after the switchover, the old ones remain in the configuration.
The impact of stale dynamic access lists is to monitor unwanted traffic.
– If the switchover is scheduled, remove the scheduled session on the initiator. Reschedule the session after the new active supervisor engine boots on the responder.
– If the Mediatrace responder SSO is not planned, after the new active supervisor engine boots, manually delete the stale dynamic access lists. CSCty75070
- If you perform an OIR on a line card, several %C4K_RKNOVA-4-INVALIDTOKENEXPIRED messages appear in the logs.
Workaround: Increase the queue limit to at least 256. CSCto57602
– Links flap for various Layer 3 protocols.
– A traffic loss of several seconds is observed during the upgrade process.
Workaround: Do not use the quick option with the issu changeversion command. CSCto51562
Workaround: Shut then no shut the interface.
Applying the workaround preemptively (i.e., entering shut then no shut on the interfaces after first switchover) prevents a failure on the subsequent switchover. CSCui49000
Workaround: Shut then no shut the interface.
Applying the workaround preemptively (i.e., entering shut then no shut on the interfaces after first switchover) prevents a failure on the subsequent switchover. CSCui49000
- If you reboot a switch, the configured value of the interface MTU size for the elements of the port channel interface does not work for IPv6 traffic.
Workaround: After the switch reloads, enter shut and no shut on the port-channel interface.
- When either the RADIUS-server test feature is enabled or RADIUS-server dead-criteria is configured, and either RADIUS-server deadtime is set to 0 or not configured, the RADIUS-server status is not properly relayed to AAA.
Workaround: Configure both dead-criteria and deadtime.
- The show ipv6 access-list command displays incorrect match counts when multicast traffic is matched to an IPv6 access list that is attached to an SVI.
- On IOS Release 15.2(1)E, the DUT MAC learn rate (4700 MAC sec) is lower than the rate (8000 MAC/sec) on IOS Release 3.4.0SG. When the macro auto monitor command is disabled on IOS Release 15.2(1)E, the rate is 13800 MAC/sec.
Resolved Caveats for Cisco IOS XE Release 3.3.2XO
This section lists the resolved caveats for Cisco IOS XE Release 3.3.2XO:
- WS-X4248 or WS-X4548- PoE modules reset PoE causing all connected PDs to lose power precipitating an outage. The following error log is observed:
*Feb 4 10:05:46.648: %C4K_CHASSIS-5-PORTSPOERESTARTED: Poe restarted for interfaces on slot 5 (count=1)
- If a GRE tunnel is configured with ip unnumbered and you write this configuration, after reloading the system, the FIA table is not reloaded (i.e., all packets for that tunnel are dropped under "UnconfiguredIpv4Fia").
Workaround: Unconfigure the reconfigure the ip unnumbered command. CSCtb14871
Workaround: Issue either sh run or write memory. CSCui35423
- When Performance Monitor feature is configured with threshold-crossing-alarms, the SNMP query FlowMetrics,FlowMonitor,Alarm returns the wrong values. Note the following MIBs:
- When you connect GLC-GE-100FX in WS-X4624-SFP-E, WS-X4640-CSFP-E or WS-X4612-SFP-E, the link doesn’t come up.
GLC-GE-100FX was tested with WS-X4624-SFP-E(HW 1.2(VID V02) and HW 2.0(VID V03)), the problem happened on GLC-GE-100FX V02 only. There was no problem with GLC-GE-100FX V01.
This issue is triggered by one of the following:
– consistent rapid flapping of mroute(s)
– constant traffic toward a group on a VLAN where SVI is configured with PIM sparse mode but an RP is disallowed [for the group]
– For flapping mroutes, find the source of the flapping mroute and prevent it.
– For a missing RP scenario, either turn off PIM on the VLAN or allow the multicast group associate with an RP. CSCul44174
- A switch crashes reliably when you issue the following command (under a VLAN) to enable unicast RPF:
- After every reboot, the SNMPv2 configuration is lost; it is present in the startup-config but not in the running config. The config doesn't work after reboot:
With a different community or without snmp-server host 192.168.131.13 vrf mgmtVrf version 2c, the config line remains intact.
Workaround: Re-apply this configuration. CSCsh92025
- A switch running cat4500e-universalk9.SPA.03.04.00.SG.151-2.SG.bin that points to an NTP server will observe forward clock shifting although NTP status shows that the sync is working.
Removing or adding the NTP configuration doesn't fix the issue.
In the following example, show clock is executed on ASR, then on a Catalyst 4500 switch. Notice that the Catalyst 4500 switch is nearly eight second behind:
- A PoE device connected to a interface on module WS-X4748-UPOE+E with WS-X45-SUP7-E will not power UP. The interface remains down or unconnected.
test cable-diagnostics tdr interface <int> CSCui45222
- A standby switch in VSS (or a redundant supervisor engine outside VSS) reboots due to config-sync failure when moving VLAN names:
New: (VLAN 1024 is renamed with the old name for VLAN 1022)
Workaround: Exit the VLAN config mode before changing the second VLAN name. CSCuj42720
This means that NMS systems cannot gather information about files on the other partitions.
- A switch may experience a low memory condition due to increased utilization under the "Chunk Manager" process.
If performance monitoring is configured with the service-policy type performance-monitor input/output < > command, your will notice that the memory held by Chunk Manager / List Headers continues to grow:
- If you configure dot1x for host-mode multi-host, phones that are in a voice VLAN do not acquire an IP address and are unable to be t registered to call manager
Workaround: Change to multi-domain or single host with CDP bypass (enable cdp/lldp on the switch). CSCuo79422
- A switch crashes with Critical software exception during config push as 'Critical software exception'
- During an HA setup, the active supervisor engine reload does not complete within the allocated time and the following error message is displayed
- High CPU is observed when sending multicast traffic provided the switch is directly connected to the source and PIM SSM is configured but no receiver exists.
Workaround: Configure control plane policy to deny Multicast SSM traffic hitting CPU.
1. Apply ACL on ingress interface deny the non-interested PIM SM multicast stream:
2. Have a dummy loopback interface enabled with PIM-SM. Configure ip igmp static-group x.x.x.x on this Loopback interface (where x.x.x.x is non-interested multicast group ip address). CSCui64652
- When PIM is enabled on an SVI interface, multicast traffic is dropped in certain scenario where it requires Layer 2 switching (Router on which Multicast (*, G) or (S, G) entry is not present for Group).
Workaround: Disable PIM SSM on the interface. CSCum47920
Moreover, mroute is improperly programmed on the switch, which is connected to multicast source.
– Apply ACL on ingress interface denying the non-interested multicast stream. Below is the example.
– Use a dummy loopback interface enabled with PIM-SM. Configure ip igmp static-group x.x.x.x on this Loopback interface (where x.x.x.x is the non-interested multicast group ip address).
Open Caveats for Cisco IOS XE Release 3.3.1XO
This section lists the open caveats for Cisco IOS XE Release 3.3.0XO:
- When an SNMP query includes the cpmCPUProcessHistoryTable, the query time is very slow, and CPU utilization of the os_info_p process (OS Info provider) increases substantially. The time required for a full walk of an almost fully populated table is 68 minutes.
- The show ipv6 access-list command displays incorrect match counts when multicast traffic is matched to an IPv6 access list that is attached to an SVI.
- When either the RADIUS-server test feature is enabled or RADIUS-server dead-criteria is configured, and either RADIUS-server deadtime is set to 0 or not configured, the RADIUS-server status is not properly relayed to AAA.
Workaround: Configure both dead-criteria and deadtime.
- If you reboot a switch, the configured value of the interface MTU size for the elements of the port channel interface does not work for IPv6 traffic.
Workaround: After the switch reloads, enter shut and no shut on the port-channel interface.
Workaround: Increase the queue limit to at least 256. CSCto57602
– Links flap for various Layer 3 protocols.
– A traffic loss of several seconds is observed during the upgrade process.
Workaround: Do not use the quick option with the issu changeversion command. CSCto51562
- A device in a guest VLAN that is connected behind a phone that is capable of 2nd-port-notification experiences packet loss following a SSO failover. The device experiences an authentication restart after the first CDP frame arrives from the phone.
- If you perform an OIR on a line card, several %C4K_RKNOVA-4-INVALIDTOKENEXPIRED messages appear in the logs.
- When you enable both Cisco TrustSec and RADIUS accounting, a disparity occurs between the RADIUS client (Cisco switch) and the RADIUS/CTS server in how the authenticator field in the header is computed for DOT1X/RADIUS accounting messages.
A Cisco IOS AAA client uses the PAC secret to compute the authenticator; Cisco Secure ACS 5.2 uses the shared secret. This behavior causes a mismatch that results in a rejection of the accounting message, and the client marks the server as unresponsive.
Workaround: None. You must disable 802.1X accounting. CSCts26844
- When more than one Equal Cost Multipath (ECMP) is available on the downstream switch, and Mediatrace is invoked to provide flow statistics, the dynamic policy does not show statistics for a flow.
Mediatrace cannot find the correct inbound interface and applies the dynamic policy on a different interface from the one used for media flow.
- When a switchover is created on the Mediatrace responder, the dynamic access list created for a monitored flow tuple is not deleted. Although the Mediatrace initiator creates another set of dynamic access lists after the switchover, the old ones remain in the configuration.
The impact of stale dynamic access lists is to monitor unwanted traffic.
– If the switchover is scheduled, remove the scheduled session on the initiator. Reschedule the session after the new active supervisor engine boots on the responder.
– If the Mediatrace responder SSO is not planned, after the new active supervisor engine boots, manually delete the stale dynamic access lists. CSCty75070
- When you add a "bfd" suffix to the snmp server host x.x.x.x configuration command, the BFD traps, ciscoBfdSessUp and ciscoBfdSessDown, are not generated.
Workaround: Do not specify a "bfd" suffix with the snmp-server host x.x.x.x configuration command. CSCtx51561
- During either a system- or user-initiated reload operation, the following message is observed when the system shuts down:
This message is not observed during a system bootup.
Workaround: None required. This message is information only. CSCtz15738
- Immediately following an SSO, the following error message may be logged by the new active route processor:
The error message is information only.
- On IOS Release 15.2(1)E, the DUT MAC learn rate (4700 MAC sec) is lower than the rate (8000 MAC/sec) on IOS Release 3.4.0SG. When the macro auto monitor command is disabled on IOS Release 15.2(1)E, the rate is 13800 MAC/sec.
This error is informational only.
- If you configure a Qos srTCM policer with actions (traffic conform, traffic exceed, and traffic violated), the marking action for exceed traffic remains inactive.
Workaround: Configure a policer with only conform-action and exceed-action and not with violate-action. CSCug49778.
- The match application name and collect application name commands appear available for flow record configuration when you use the ? help listings. However, the following configuration is otherwise unsupported: show flow monitor i monitor-name i cache displays the application name as “unknown;” and the application table is not exported. So, the application name field cannot be decoded when exported.
Workaround: Do not configure the application name field as a key or non-key field of a flow record.
- IPv6 access-list counters do not increment when a policy-map associated with a class-map that matches a v6 ACL is applied to a physical interface and matching traffic is sent.
Workaround: Use PEAP-GTC or any other method. CSCud66899
Workaround: Shut then no shut the interface.
Applying the workaround preemptively (i.e., entering shut then no shut on the interfaces after first switchover) prevents a failure on the subsequent switchover. CSCui49000
There is no functional impact when this message is printed.
– Apply ACL on an ingress interface to deny the non-interested multicast stream, as follows:
– Enable PIM-SM on a dummy loopback interface by configuring ip igmp static-group x.x.x.x (where x.x.x.x is the non-interested multicast group IP address)
- A device in a guest VLAN that is connected behind a phone that is capable of 2nd-port-notification experiences packet loss following a SSO failover. The device experiences an authentication restart after the first CDP frame arrives from the phone.
- When more than one Equal Cost Multipath (ECMP) is available on the downstream switch, and Mediatrace is invoked to provide flow statistics, the dynamic policy does not show statistics for a flow.
Mediatrace cannot find the correct inbound interface and applies the dynamic policy on a different interface from the one used for media flow.
Resolved Caveats for Cisco IOS XE Release 3.3.1XO
This section lists the resolved caveats for Cisco IOS XE Release 3.3.1XO:
- If you are running "cat4500e-universalk9.SPA.03.05.00.E.152-1.E.bin c3750e-universalk9-mz.152-1.E.bin" SNMP could cause the device to suddenly crash:
When polling the device to get an instance for CafSessionEntry object, as follows:
In redundant scenarios, switchover occurs repeatedly.
Workaround: Create SNMP view and exclude the OID, as follows:
- If you are using dot1x and dACL and the same dACL is applied on multiple ports, one device per port, so device tracking is not substituting "ANY" with the "IP address in dACL," the dACL is either not applied on the port or deactivated on the ports on which it was previously applied.
The following error message is observed in the output of the debug ip admission api command:
Workaround: Assign different names for the ACLs on each port. CSCuj88557
- When the same ACL is installed on two ports, ACS-configured Dynamic ACLs are neither applied nor removed from the hardware.
– Configured tags (anywhere in topology) are received by a router operating with EIGRP Rel. 12 and later.
– Query received for the route updated with tags.
- On a switch running "ct5760-ipservicesk9.bin cat3k_caa-universalk9.bin cat4500e-universalk9.bin" configured with device-originated UDP services (includes but not limited to the features: TFTP, Energywise, DNS, and Cisco TrustSec, UDP based entries are not deleted from the flowmgr table resulting in a crash or poor system response, and CPU hog messages display.
To confirm that you are affected by this bug, issue the following:
The output lists the entries in the flowmgr table. When this issue is seen, the flowmgr entries continue to increment (i.e., flow details are still present even after the connection is closed.)
Reloading is required to clean up the flowmgr entries that are present in the flowmgr table. Replace tftp with ftp, if possible. CSCuh09324
- Removing the default configuration resulting from the monitor session id filter packet-type good rx command from an active SPAN session triggers HSRP and EIGRP flaps making the switch unreachable from directly connected peers.
Workaround: Restore the default config of the monitor session id filter packet-type good rx command and issue shut then no shut on the 'err-disabled' ports. CSCui56867
- A vulnerability in the implementation of the IP version 6 (IPv6) protocol stack in Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause I/O memory depletion on an affected device that has IPv6 enabled. The vulnerability is triggered when an affected device processes a malformed IPv6 packet.
Cisco has released free software updates that address this vulnerability. There are no workarounds to mitigate this vulnerability.
This advisory is available at the following link:
http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20140326-ipv6
Note: The March 26, 2014, Cisco IOS Software Security Advisory bundled publication includes six Cisco Security Advisories. All advisories address vulnerabilities in Cisco IOS Software. Each Cisco IOS Software Security Advisory lists the Cisco IOS Software releases that correct the vulnerability or vulnerabilities detailed in the advisory as well as the Cisco IOS Software releases that correct all Cisco IOS Software vulnerabilities in the March 2014 bundled publication.
Individual publication links are in Cisco Event Response: Semiannual Cisco IOS Software Security Advisory Bundled Publication at the following link: http://www.cisco.com/web/about/security/intelligence/Cisco_ERP_mar14.html
Workaround: See published Cisco Security Advisory CSCui59540
- A vulnerability in the Internet Key Exchange Version 2 (IKEv2) module of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause a reload of the affected device that would lead to a denial of service (DoS) condition.
The vulnerability is due to how an affected device processes certain malformed IKEv2 packets. An attacker could exploit this vulnerability by sending malformed IKEv2 packets to an affected device to be processed. An exploit could allow the attacker to cause a reload of the affected device that would lead to a DoS condition.
Although IKEv2 is automatically enabled on a Cisco IOS Software and Cisco IOS XE Software devices when the Internet Security Association and Key Management Protocol (ISAKMP) is enabled, the vulnerability can be triggered only by sending a malformed IKEv2 packet.
Only IKEv2 packets can trigger this vulnerability.
Cisco has released free software updates that address this vulnerability. There are no workarounds to mitigate this vulnerability.

Workaround: See published Cisco Security Advisory CSCui88426
- A switch may leak memory in the I/O pool due to mDNS traffic. The pool in which the leak is seen is dependent on the size of the incoming packet
Alternatively, the input queue on the interface may be stuck at the maximum size and starts to drop further traffic. This can cause pings to fail and protocols like HSRP,OSPF etc to not establish.
This symptom occurs when mDNS traffic is sent to the switch.
Workaround: Apply an ACL to the inbound interface. This will drop the traffic and buffers will not leak. CSCuj58950
- Multiple iterations of the show platform cpu packet driver command cause ARP, IGMP and other control protocols to stop processing and displays the following:
– When the switch boots, toggle "ipv6 snooping" under "vlan configuration 1" soon after switch bootup CSCuj73571
- A vulnerability exists in Cisco IOS software where an unauthenticated attacker could bypass access control policies when the Object Groups for Access Control Lists (ACLs) feature is used. Cisco has released free software updates that address this vulnerability. There are no workarounds for this vulnerability other than disabling the Object Groups for ACLs feature.
This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20090923-acl.shtml.
Note: The September 23, 2009, Cisco IOS Security Advisory bundled publication includes eleven Security Advisories. Ten of the advisories address vulnerabilities in Cisco IOS Software, and one advisory addresses a vulnerability in Cisco Unified Communications Manager.

- When you issue either the device-sensor accounting or access-session accounting attributes command, subscriber accounting is not propagated from the switch to the ISE.
Workaround: Don’t enable the device-sensor accounting. :CSCuj56845
Workaround: Apply the following SNMP view to restrict polling of the MIB:
- When authentication control direction in and mab are configured together on the interface, a MAB session is not triggered.
Workaround: Use either the authentication control-direction both or authentication open command. CSCuo50590
- Very rarely, the following error message displays on the active supervisor engine before the standby supervisor engine achieves standby hot in SSO operating mode:
This error does not impact functionality. However, the uplink ports of the standby supervisor engine loses functionality if the standby supervisor engine becomes the active supervisor engine.
Workaround: Reinsert the standby supervisor engine. CSCui25419
Open Caveats for Cisco IOS XE Release 3.3.0XO
This section lists the open caveats for Cisco IOS XE Release 3.3.0XO:
- When an SNMP query includes the cpmCPUProcessHistoryTable, the query time is very slow, and CPU utilization of the os_info_p process (OS Info provider) increases substantially. The time required for a full walk of an almost fully populated table is 68 minutes.
- The show ipv6 access-list command displays incorrect match counts when multicast traffic is matched to an IPv6 access list that is attached to an SVI.
- When either the RADIUS-server test feature is enabled or RADIUS-server dead-criteria is configured, and either RADIUS-server deadtime is set to 0 or not configured, the RADIUS-server status is not properly relayed to AAA.
Workaround: Configure both dead-criteria and deadtime.
- If you reboot a switch, the configured value of the interface MTU size for the elements of the port channel interface does not work for IPv6 traffic.
Workaround: After the switch reloads, enter shut and no shut on the port-channel interface.
Workaround: Increase the queue limit to at least 256. CSCto57602
– Links flap for various Layer 3 protocols.
– A traffic loss of several seconds is observed during the upgrade process.

Resolved Caveats for Cisco IOS XE Release 3.3.0XO
This section lists the resolved caveats for Cisco IOS XE Release 3.3.0XO:
- When a port connected to a CDP speaker goes down, a small memory leak occurs (typically less than 300 bytes).
Workaround: Disable CDP on interfaces that may flap frequently. CSCub85948
Troubleshooting
These sections provide troubleshooting guidelines for the Catalyst 4500 series switches running IOS supervisor engines:
- Netbooting from ROMMON, page 39
- Troubleshooting at the System Level, page 40
- Troubleshooting Modules, page 40
- Troubleshooting MIBs, page 40
Netbooting from ROMMON
Netbooting using a boot loader image is not supported. Instead, use one of the following options to boot an image:
1. Boot from an SD card by entering the following command:
The ROMMON TFTP boot is very similar to the BOOTLDR TFTP boot, except that:
– the BOOTLDR variable should not be set
– the TFTP server must be accessible from the Ethernet management port on the supervisor engine.
To boot from ROMMON, perform the following tasks while in ROMMON mode:
a. Ensure that the Ethernet management port on the supervisor engine is physically connected to the network.
b. Verify that bootloader environment is not set by entering the unset bootldr command.
c. Set IP address of the Ethernet management port on the supervisor engine by entering the following command: set interface fa1 ip_address ip_mask
For example, to set the supervisor engine Ethernet port with an IP address 172.16.1.5 and IP mask 255.255.255.0, enter the following command:
d. Set default gateway for the Ethernet management port on the supervisor engine by entering the following command: set ip route default gateway_ip_address. The default gateway should be directly connected to the supervisor engine Ethernet management port subnet.
e. Ping the TFTP server to ensure that there is connectivity to the server from the Ethernet management port on the supervisor engine by entering the following command: ping tftp_server_ip_address.
f. Once the ping is successful, boot the image from the TFTP server by entering the following command: boot tftp:// tftp_server_ip_address / image_path_and_file_name
For example, to boot the Cisco IOS XE image cat4500e-universalk9.03.01.00.SG.150-1.XO.bin located on the TFTP server 172.16.1.8, enter the following command:
Troubleshooting at the System Level
This section contains troubleshooting guidelines for system-level problems:
- When the system is booting and running power-on diagnostics, do not reset the switch.
- Ensure that you do not mix the serial and Ethernet cables plugged into the supervisor engine. The Fast Ethernet port (10/100 MGT) on the supervisor engine is inoperative. An Ethernet cable plugged into the Fast Ethernet port is active only in ROMMON mode.
Troubleshooting Modules
This section contains troubleshooting guidelines for modules:
- When you hot insert a module into a chassis, always use the ejector levers on the front of the module to seat the backplane pins properly. Inserting a module without using the ejector levers might cause the supervisor engine to display incorrect messages about the module. For module installation instructions, refer to the Catalyst 4500 Series Module Installation Guide.
- Whenever you connect an interface that has duplex set to autonegotiate to an end station or another networking device, ensure that the other device is configured for autonegotiation as well. If the other device is not set to autonegotiate, the port set to autonegotiate will remain in half-duplex mode, which can cause a duplex mismatch resulting in packet loss, late collisions, and line errors on the link.
Troubleshooting MIBs
For general information on MIBs, RMON groups, and traps, refer to the Cisco public MIB directory ( http://www.cisco.com/public/sw-center/netmgmt/cmtk/mibs.shtml). For information on the specific MIBs supported by the Catalyst 4500 series switches, refer to the Catalyst 4000 MIB Support List located at ftp://ftp.cisco.com/pub/mibs/supportlists/cat4000/cat4000-supportlist.html.
