We recommend that you use the WAAS Central Manager instead of the WAAS CLI to configure network
settings, but if you want to use the CLI, see the following commands in the Cisco Wide Area Application
Services Command Reference: interface, ip address, port-channel, and primary-interface.
Network interfaces are named as follows on WAAS devices:
• WAVE-274/474—Have one built-in Ethernet interface named GigabitEthernet 1/0.
• WAE-512/612/7326/674/7341/7371 and WAVE-574—Have two built-in Ethernet interfaces named
GigabitEthernet 1/0 and GigabitEthernet 2/0.
• WAVE-294/594/694/7541/7571/8541—Have two built-in Ethernet interfaces named
GigabitEthernet 0/0 and GigabitEthernet 0/1. Additional interfaces on the Cisco Interface Module
and AppNav Controller Interface Module are named GigabitEthernet 1/0 to 1/11 or
TenGigabitEthernet 1/0 to 1/3, depending on the number and type of ports.
• NME-WAE devices—Have an internal interface to the router that is designated 1/0 and an external
interface that is designated 2/0.
• SM-SRE devices—Have an internal interface to the router that is designated 1/0 and an external
interface that is designated 2/0.
Note We strongly recommend that you do not use half-duplex connections on the WAE or on routers, switches,
or other devices. Half duplex impedes performance and should not be used. Check each Cisco WAE
interface and the port configuration on the adjacent device (router, switch, firewall, and WAE) to verify
that full duplex is configured.
When connecting an AppNav Controller to a Cisco Nexus 7000 Series switch, the interfaces on both
devices must be set to the same auto-negotiate setting: either both on or both off. If they are set
differently, switch link flapping can occur.
Note Layer 3 interfaces may drop bridge protocol data unit (BPDU) packets. This does not affect data traffic.
