Command
show etherchannel [channel-group-number {detail |
port | port-channel | protocol | summary}] {detail |
load-balance | port | port-channel | protocol |
summary}
show pagp [channel-group-number] {counters |
internal | neighbor}
show pagp [channel-group-number] dual-active
show lacp [channel-group-number] {counters |
internal | neighbor}
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
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.
Note An interface can be an aggregation of ports (an EtherChannel), or a single physical port in access or trunk
mode.
