Command History
Usage Guidelines
After enabling Layer 2 protocol tunneling on an access or IEEE 802.1Q tunnel port by using the l2protocol-tunnel interface configuration command, you can configure some or all of these parameters:
The showl2protocol-tunnel command displays only the ports that have protocol tunneling enabled.
The showl2protocol-tunnelsummary command displays the ports that have protocol tunneling enabled, regardless of whether the port is down or currently configured as a trunk.
Examples
The following example is an output from the show l2protocol-tunnel command:
Router# show l2protocol-tunnel COS for Encapsulated Packets: 5 Drop Threshold for Encapsulated Packets: 0
This example shows how to display a summary of Layer 2-protocol tunnel ports:

Description
Port
Port on which link bundling is configured.
Partner System ID
Peer’s LACP system identification (sys-id). It is a combination of the system priority and the MAC address of the peer device.
Partner Port Number
Port number on the peer device
Age
Number of seconds since the last LACP PDU was received on the port.
Flags
Indicators of device activity.
Port Priority
Port priority setting.
Admin Key
Defines the ability of a port to aggregate with other ports.
Oper Key
Determines the aggregation capability of the link.
Port State
Activity state of the port.
See the Port State description in the show lacp internal Field Descriptions table for state variables.
If no PDUs have been received, the default administrative information is displayed in braces.
show link state group
To display the link-state group information., use the showlinkstategroup command in user EXEC or privileged EXEC mode .
Usage Guidelines
Link State Ttracking (LST), also known as trunk failover, is a feature that binds the link state of multiple interfaces. When you configure LST for the first time, add upstream interfaces to the link state group before adding the downstream interface, otherwise the downstream interfaces would move into error-disable mode. The maximum number of link state groups configurable is 10.
Examples
The following example displays the link-state group information:
Router# enable Router# show link state group 1 Link State Group: 1 Status: Enabled, Down Router> show link state group detail (Up):Interface up (Dwn):Interface Down (Dis):Interface disabled Link State Group: 1 Status: Enabled, Down Upstream Interfaces : Gi3/5(Dwn) Gi3/6(Dwn) Downstream Interfaces : Gi3/1(Dis) Gi3/2(Dis) Gi3/3(Dis) Gi3/4(Dis) Link State Group: 2 Status: Enabled, Down Upstream Interfaces : Gi3/15(Dwn) Gi3/16(Dwn) Gi3/17(Dwn) Downstream Interfaces : Gi3/11(Dis) Gi3/12(Dis) Gi3/13(Dis) Gi3/14(Dis) (Up):Interface up (Dwn):Interface Down (Dis):Interface disabledshow mac-address-table dynamic
To display dynamic MAC address table entries only, use the showmac-address-tabledynamic command in privileged EXEC mode.

Usage Guidelines
Cisco 2600 Series, Cisco 3600 Series, and Cisco 3700 Series Routers
The showmac-address-tabledynamic command output for an EtherChannel interface changes the port-number designation (for example, 5/7) to a port-group number.
Catalyst Switches
The keyword definitions for the protocol argument are:
- ip --Specifies IP protocol
- ipx --Specifies Internetwork Packet Exchange (IPX) protocols
- assigned --Specifies assigned protocol entries
- other --Specifies other protocol entries
The showmac-address-tabledynamic command output for an EtherChannel interface changes the port-number designation (for example, 5/7) to a port-group number.
Catalyst 6500 Series Switches
The mac-addressis a 48-bit MAC address and the valid format is H.H.H.
The optional modulenum keyword and argument are supported only on DFC modules. The modulenumkeyword and argument designate the module number.
Examples
The following examples show how to display all dynamic MAC address entries. The fields shown in the various displays are self-explanatory.
