Cisco Systems 3750G manual Verifying Interface Settings and Port Operation

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.

		STP	Admin	Physical	Physical		Link	Link	Mcast
Pr	Type	Stat	Mode	Mode	Status		Status	Trap	Appliance	POE
--	-------	---- -------		----------	----------		------	-------	--------- -------
1	Normal	Forw Enable		Auto	1000	Full	Up	Enable	Enable	N/A
2	Normal	Forw Enable		Auto	1000	Full	Up	Enable	Enable	N/A

A link status of Up means that the controller ports are fully operational.
