2. Enter the port-channel sub-mode.

switch(conf-if-te-0/1)#interface port-channel 63

3. Configure the minimum links.

switch(conf-if-po-63)#minimum-links 3

Configuring interface tracking

The track interface command lets you track one or more external ports on your switch. Only external physical interfaces and port-channel interfaces can be tracked. The show output for internal interfaces is enhanced to include the information of which external interfaces are being tracked. Additionally, there is a command provided to enable (or disable) the tracking under internal interface sub-mode. This command is track enable. External interfaces can be tracked only if tracking is enabled by means of this command.

The semantics of track interface are as follows:

•One internal interface can track one or more external interfaces.

•Multiple internal interfaces can track the same external interface.

•If multiple external interfaces are being tracked by one internal interface, only if all of them go DOWN, the internal interface should go DOWN.

•Only the operational status of the external interface is tracked – not the admin state.

•If multiple internal interfaces are tracking a single external interface and if the external interface goes DOWN, all those internal interfaces should go DOWN.

•A maximum of eight external interfaces can be tracked from an internal interface.

•Forward referenced port-channels (non-existing port-channels) are tracked.

In the following procedure, tracking is enabled and the internal interface 0/8 is tracking external interfaces 0/15,0/16, and 0/17. Perform the following steps from global configuration mode.

1. Select the internal interface to use as the tracking monitor.

switch(config)#interface intengigabitethernet 0/8

2. Enable tracking.

switch(conf-if-int-0/8)#track enable

3. Select one or more external interfaces to be tracked.

switch(conf-if-int-0/8)# switch(conf-if-int-0/8)# switch(conf-if-int-0/8)#

track interface extengigabitethernet 0/15 track interface extengigabitethernet 0/16 track interface extengigabitethernet 0/17

Clearing LACP counter statistics on a LAG

To clear LACP counter statistics, perform the following task from Privileged EXEC mode.

1.Enter the clear command to clear the LACP counter statistics for the specified LAG group number.

switch#clear lacp 42 counters
