Verifying Interface Settings and Port Operation
Follow these steps to verify that your interface configurations have been set properly and that the
controller ports are operational.
Step 1
Enter show interface summary, and press Enter. This display shows the controller interface
configurations:
Interface Name Port Vlan Id IP Address Type Ap Mgr
------------------------------ ---- -------- -------------- ------- -----
ap-manager LAG 10 10.91.104.99 Static Yes
management LAG 10 10.91.104.93 Static No
service-port N/A N/A 10.10.0.9 Static No
virtual N/A N/A 1.1.1.1 Static No
Link aggregation (LAG) is always enabled for the integrated wireless LAN controller and
cannot be disabled. LAG bundles all of the controller distribution system ports into a
single IEEE 802.3ad port channel. See the Cisco Wireless LAN Controller Configuration
Guide 4.0 or later for more information.
Step 2
Enter show port summary, and press Enter. This display shows the status of the controller
distribution system ports, which serve as the data path between the controller and the
Cisco lightweight access points and to which the controller management and AP-manager
interfaces are mapped.
