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.

Link-state tracking, also known as trunk failover, is a feature that binds the link state of multiple 
interfaces. Link-state tracking provides redundancy in the network when used with server network 
interface card (NIC) adapter teaming. When the server network adapters are configured in a primary or 
secondary relationship known as teaming and the link is lost on the primary interface, connectivity 
transparently changes to the secondary interface.

 shows a network configured with link-state tracking. To enable link-state 

tracking, create a link-state group, and specify the interfaces that are assigned to the link-state group. An 
interface can be an aggregation of ports (an EtherChannel), a single physical port in access or trunk 
mode, or a routed port. In a link-state group, these interfaces are bundled together. The downstream 
interfaces

 are bound to the upstream interfaces. Interfaces connected to servers are referred to as 

 interfaces, and interfaces connected to distribution switches and network devices are 

referred to as upstream interfaces. 

 [channel-group-number] dual-active

Displays the dual-active detection status.

 [channel-group-number] {counters | 

| neighbor}

Displays LACP information such as traffic information, the 
internal LACP configuration, and neighbor information.
