82 Chapter 4: Network Integration and Interception

The command output for each physical interface is the same as it is without EtherChannel

conﬁgured, with the following exceptions:

• The SLAVE ﬂag is set, indicating that the interface is part of an EtherChannel group.

• The Ethernet address for each interface is the same, and matches the MAC address

used by the virtual EtherChannel interface.

Using the Standby Interface Feature

When you do not require increased interface bandwidth but desire interface redundancy,

you can use the standby interface feature. The standby interface feature conﬁgures both

physical interfaces on the WAE in an active/standby failover pair. At any point in time, only

one of the interfaces is active and passing trafﬁc. The second interface, or standby interface,

is passively waiting to take over in the event that the active interface fails. When the active

interface fails, the standby interface takes over the active role. When the previously active

interface recovers, it assumes the standby role. The interface with the highest priority is

preferred as the active interface. The priority is conﬁgurable.

The standby interface feature has become a popular choice for deployments because the

WAE can be physically connected to two different LAN switches. This prevents the failure

of a single LAN switch or switchport from disrupting the operation of the WAE. Figure 4-3

shows an example of a WAE connected using the standby interface feature.
