Chapter 37 Configuring EtherChannels and Link-State Tracking
Displaying EtherChannel, PAgP, and LACP Status
To return the LACP port priority to the default value, use the no lacp port-priority interface
configuration command.
Displaying EtherChannel, PAgP, and LACP Status
You can clear PAgP channel-group information and traffic counters by using the clear pagp
{channel-group-number counters | counters} privileged EXEC command.
You can clear LACP channel-group information and traffic counters by using the clear lacp
{channel-group-number counters | counters} privileged EXEC command.
For detailed information about the fields in the displays, see the command reference for this release.
Understanding Link-State Tracking
Note To use Link-state tracking, the switch must be running the LAN Base image.
Link-state tracking, also known as trunk failover, is a feature that binds the link state of multiple
interfaces. For example, link-state tracking provides redundancy in the network when used with server
NIC adapter teaming. When the server network adapters are configured in a primary or secondary
relationship known as teaming, if the link is lost on the primary interface, connectivity is transparently
changed to the secondary interface.
