EtherChannel Link Failover

If a link within an EtherChannel fails, traffic previously carried over that failed link moves to the remaining
links within the EtherChannel. If traps are enabled on the switch, a trap is sent for a failure that identifies the
switch, the EtherChannel, and the failed link. Inbound broadcast and multicast packets on one link in an
EtherChannel are blocked from returning on any other link of the EtherChannel.

Channel Groups and Port-Channel Interfaces
An EtherChannel comprises a channel group and a port-channel interface. The channel group binds physical
ports to the port-channel interface. Configuration changes applied to the port-channel interface apply to all
the physical ports bound together in the channel group.
