show queueing interface
To display queueing information, use the show queueing interface command.
show queueing interface {{interface interface-number} | {null interface-number} | {vlan vlan-id}}
Syntax Description

12.2(18)ZY |
Support for this command was introduced. |
Usage Guidelines
The interface-number argument designates the module and port number. Valid values for interface-number depend on the specified interface type and the chassis and module that are used. For example, if you specify a Gigabit Ethernet interface and have a 48-port 10/100BASE-T Ethernet module that is installed in a 13-slot chassis, valid values for the module number are from 1 to 13 and valid values for the port number are from 1 to 48.
The show queueing interface command does not display the absolute values that are programmed in the hardware. Enter the show qm-sp port-data command to verify the values that are programmed in the hardware.
Examples
This example shows how to display queueing information:
Router# show queueing interface fastethernet 5/1

show running-config
To display the status and configuration of the module, Layer 2 VLAN, or interface, use the show running-config command.

Support for this command was introduced. |
Usage Guidelines
In some cases, you might see a difference in the duplex mode that is displayed between the show interfaces command and the show running-config command. In this case, the duplex mode that is displayed in the show interfaces command is the actual duplex mode that the interface is running. The show interfaces command shows the operating mode for an interface, while the show running-config command shows the configured mode for an interface.
The show running-config command output for an interface might display the duplex mode but no configuration for the speed. This output indicates that the interface speed is configured as auto and that the duplex mode shown becomes the operational setting once the speed is configured to something other than auto. With this configuration, it is possible that the operating duplex mode for that interface does not match the duplex mode that is shown with the show running-config command.
Examples
This example shows how to display the module and status configuration for all modules:
Router#

Usage Guidelines
The show snmp mib ifmib ifindex command allows you to display SNMP interface index identification numbers (ifIndex values) that are assigned to interfaces and subinterfaces using the CLI. This command allows you to view these values without using a Network Management Station.
If a specific interface is not specified using the optional interface-type, slot, port-adapter, and port arguments, the ifDescr and ifIndex pairs of all interfaces and subinterfaces present on the system are shown.
Use the show snmp mib ifmib ifindex ? command to determine the options available on your system. Typical interface-types values include async, dialer, ethernet, fastEthernet, and serial.
Examples
This example shows how to display the ifIndex for a specific interface:
Router# show snmp mib ifmib ifIndex Ethernet2/0
Ethernet2/0: Ifindex = 2
This example shows how to display the ifIndex for all interfaces:
Router# show snmp mib ifmib ifindex

Usage Guidelines
The pos, atm, and ge-wan keywords are supported on Catalyst 6500 series switches that are configured with a Supervisor Engine 2 only.
The port-channel number values from 257 to 282 are supported on the CSM and the FWSM only.
The interface-number argument designates the module and port number. Valid values for interface-number depend on the specified interface type and the chassis and module that are used. For example, if you specify a Gigabit Ethernet interface and have a 48-port 10/100BASE-T Ethernet module that is installed in a 13-slot chassis, valid values for the module number are from 2 to 13 and valid values for the port number are from 1 to 48.
When checking spanning tree-active states and you have a large number of VLANs, you can enter the show spanning-tree summary total command. You can display the total number of VLANs without having to scroll through the list of VLANs.

Prio.Nbr |
Port ID that consists of the port priority and the port number. |
Status |
Status information; valid values are as follows: •P2p/Shr—The interface is considered as a point-to-point (resp. shared) interface by the spanning tree. •Edge—PortFast has been configured (either globally using the default command or directly on the interface) and no BPDU has been received. •*ROOT_Inc, *LOOP_Inc, *PVID_Inc, and *TYPE_Inc—The port is in a broken state (BKN*) for an inconsistency. The port would be Root inconsistent, Loopguard inconsistent, PVID inconsistent, or Type inconsistent. •Bound(type)—When in MST mode, identifies the boundary ports and specifies the type of the neighbor (STP, RSTP, or PVST). •Peer(STP)—When in PVRST rapid-pvst mode, identifies the port connected to a previous version of the 802.1D bridge. |

To display the information about the MST protocol, use the show spanning-tree mst command.

Support for this command was introduced. |
Usage Guidelines
The valid values for interface depend on the specified interface type and the chassis and module that are used. For example, if you specify a Gigabit Ethernet interface and have a 48-port 10/100BASE-T Ethernet module that is installed in a 13-slot chassis, valid values for the module number are from 2 to 13 and valid values for the port number are from 1 to 48.
The number of valid values for port-channel number are a maximum of 64 values ranging from 1 to 282. The port-channel number values from 257 to 282 are supported on the CSM and the FWSM only.
The number of valid values for vlan are from 1 to 4094.
Valid values for instance-id are from 0 to 4094.
In the output display of the show spanning-tree mst configuration command, a warning message may display. This message appears if you do not map secondary VLANs to the same instance as the associated primary VLAN. The display includes a list of the secondary VLANs that are not mapped to the same instance as the associated primary VLAN. The warning message is as follows:
These secondary vlans are not mapped to the same instance as their primary:
-> 3
In the output display of the show spanning-tree mst configuration digest command, if the output applies to both standard and prestandard bridges at the same time on a per-port basis, two different digests are displayed.
If you configure a port to transmit prestandard BPDUs only, the prestandard flag displays in the show spanning-tree commands. The variations of the prestandard flag are as follows:
•Pre-STD (or prestandard in long format)—This flag displays if the port is configured to transmit prestandard BPDUs and if a prestandard neighbor bridge has been detected on this interface.
•Pre-STD-Cf (or prestandard (config) in long format)—This flag displays if the port is configured to transmit prestandard BPDUs but a prestandard BPDU has not been received on the port, the autodetection mechanism has failed, or a misconfiguration, if there is no prestandard neighbor, has occurred.
•Pre-STD-Rx (or prestandard (rcvd) in long format)—This flag displays when a prestandard BPDU has been received on the port but it has not been configured to send prestandard BPDUs. The port will send prestandard BPDUs, but we recommend that you change the port configuration so that the interaction with the prestandard neighbor does not rely only on the autodetection mechanism.
If the configuration is not prestandard compliant (for example, a single MST instance has an ID that is greater than or equal to 16), the prestandard digest is not computed and the following output is displayed:
Router# show spanning-tree mst configuration digest
Name [region1]
Revision 2 Instances configured 3
Digest 0x3C60DBF24B03EBF09C5922F456D18A03

MST BPDUs include an MST configuration identifier (MSTCI) that consists of the region name, region revision, and an MD5 digest of the VLAN-to-instance mapping of the MST configuration.

Support for this command was introduced. |
Usage Guidelines
This command is supported on Fast Ethernet, Gigabit Ethernet, and 10-Gigabit Ethernet ports only.
When you enter a TopN request, a round of polling is performed, the counters for all the applicable ports in the Catalyst 6500 series switch are read, and the information is saved. The TopN process then sleeps for the specified interval. After wakeup, another round of polling is performed and the counter information from the ports is read. The difference between the two sets of data is stored. The ports are then sorted, the ports choose from one of the seven types of statistics information, and a TopN report is generated.
The port statistics will not be displayed in the following cases:
•If a port is not present during the first poll.
•If a port is not present during the second poll.
•If a port's speed or duplex changes during the polling interval.
•If a port's type changes from Layer 2 to Layer 3 or Layer 3 to Layer 2 during the polling interval.
Note For the report display format, due to the 80 characters per line limitation, only 10 spaces are reserved for the Tx/Rx-okts, Tx/Rx-bcst, and Tx/Rx-mcst columns. When these columns are larger than 10 digits, the display wraps around to the next line.
When you start the TopN processes from a Telnet session and the Telnet session is terminated before the TopN processes are completed, all the backgound TopN processes continue and generate the TopN reports, but the foreground TopN processes are terminated once the Telnet session is terminated.
When the TopN report is being generated against a large number of ports (for example, 13 slot x 96 ports/slot) in a very short interval (10 seconds), the actual interval time between the first and second polling may be longer than the specified interval time because polling takes time.

Usage Guidelines
Each Ethernet switch port and Ethernet repeater group belong to only one VLAN. Trunk ports can be on multiple VLANs.
If you shut down a VLAN using the state suspend or the state active command, these values appear in the Status field:
•suspended—VLAN is suspended.
•active—VLAN is active.
If you shut down a VLAN using the shutdown command, these values appear in the Status field:
•act/lshut—VLAN status is active but shut down locally.
•sus/lshut—VLAN status is suspended but shut down locally.
If a VLAN is shut down internally, these values appear in the Status field:
•act/ishut—VLAN status is active but shut down internally.
•sus/ishut—VLAN status is suspended but shut down internally.
If a VLAN is shut down locally and internally, the value that is displayed in the Status field is act/ishut or sus/ishut. If a VLAN is shut down locally only, the value that is displayed in the Status field is act/lshut or sus/lshut.
Separate VLAN ranges with a hyphen, and separate VLANs with a comma and no spaces in between. For example, you can enter the following:
Router#
show vlan id 1-4,3,7,5-20

|
|
---|---|
12.2(18)ZY |
Support for this command was introduced. |
Usage Guidelines
The show vlan filter map-name interface command accepts only ATM, POS, or serial interface types. If your system is not configured with any of these interface types, the interface interface interface-number keyword and arguments are not provided.
The interface-number argument designates the module and port number. Valid values for interface-number depend on the specified interface type and the chassis and module that are used. For example, if you specify a Gigabit Ethernet interface and have a 48-port 10/100BASE-T Ethernet module that is installed in a 13-slot chassis, valid values for the module number are from 2 to 13 and valid values for the port number are from 1 to 48.
If you do not specify an optional keyword and argument, all mappings are displayed. If you enter access-map map_name, all the VLANs and interfaces that are associated with the specified map are shown. If you enter vlan vlan-id or interface interface interface-number, its associated access map, if existing, is shown.
In the output for VACLs on VLANs, the following applies:
•Configured on VLANs—User configured
•Active on VLANs—VLAN list on which the VACL is active
Examples
This example shows how to display mappings between the VACLs and the VLANs and the VACLs and the interfaces:
Router# show vlan filter
