Dell Converged Enhanced Ethernet Administrator’s Guide 7153-1002116-01LACP configuration and management 72. Enter the port-channel sub-mode.switch(conf-if-te-0/1)#interface port-channel 633. Configure the minimum links.switch(conf-if-po-63)#minimum-links 3Configuring interface trackingThe track interface command lets you track one or more external ports on your switch. Onlyexternal physical interfaces and port-channel interfaces can be tracked. The show output forinternal interfaces is enhanced to include the information of which external interfaces are beingtracked. Additionally, there is a command provided to enable (or disable) the tracking underinternal interface sub-mode. This command is track enable. External interfaces can be tracked onlyif 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 goDOWN, 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 externalinterface 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 externalinterfaces 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 0/82. Enable tracking.switch(conf-if-int-0/8)#track enable3. Select one or more external interfaces to be tracked.switch(conf-if-int-0/8)#track interface extengigabitethernet 0/15switch(conf-if-int-0/8)#track interface extengigabitethernet 0/16switch(conf-if-int-0/8)#track interface extengigabitethernet 0/17Clearing LACP counter statistics on a LAGTo 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 groupnumber.switch#clear lacp 42 counters
