When using the show etherchannel command, the number option specifies the port
channel or channel group number of the channel you want to view. The show interfaces
command enables you to specify individual members of the channel and view the
EtherChannel parameters for those interfaces.

Feature Example

The following example shows the configuration of interfaces Gigabit Ethernet 1/1 and
Gigabit Ethernet 2/1 on Distribution_Switch_A as a Layer 3 channel. This interface acts as
the gateway for all the clients connected to Access_Switch_A. Figure 5-2 shows the net-
work topology for this configuration example.
