the channel group. The EtherChannel interface uses the MAC address from one of the physical

interfaces in the group. The same MAC address is used persistently for the EtherChannel

interface, even if the physical interface associated with that MAC address goes down. The

formation of an EtherChannel in WAAS is based purely on device conﬁguration. WAAS

does not support Cisco Port Aggregation Protocol (PAgP) or 802.3ad Link Aggregation

Control Protocol (LACP). When conﬁguring EtherChannel between a WAE and a LAN

switch, the channel mode on the LAN switch should be set to On for the WAE EtherChannel.

By default, the WAE load balances packets across all available interfaces in the channel

group using a round-robin algorithm. WAAS also supports load balancing using destination

IP address or destination MAC address.

Figure 4-2 shows a WAE connected to a single LAN switch using EtherChannel.

EtherChannel Conﬁguration

Conﬁguring EtherChannel in WAAS involves the following steps:

Step 1 Create a virtual PortChannel interface.

Step 2 Conﬁgure an IP address and subnet mask for the PortChannel interface.

Step 3 Assign the physical interfaces to the PortChannel.
