FAQ and Troubleshooting Guide for the CiscoWorks Wireless LAN Solution Engine
Q.
Why is hostname (device name), sysContact, and sysLocation information
not updated in the WLSE after I change these parameters on the access point?
A.
The hostname (device name), sysContact, and sysLocation parameters are
updated during discovery, not during inventory. Make sure you schedule a
periodic discovery under Administration > Discover > Scheduled Discovery.
Q.
What is an invalid CDP seed?
A.
An invalid seed is a device that does not run Cisco Discovery Protocol (CDP),
such as a PC or workstation). Such a device does not function as a seed
because it does not allow the WLSE to traverse the network and find other
devices. In the discovery run log, invalid seeds are shown as SNMP
unreachable.
Q.
Can I discover devices if CDP is disabled?
A.
If CDP is disabled on network devices, you can still discover access points by
entering the IP addresses of all of them on the WLSE as seed values.
However, the WLSE cannot discover switches directly attached to such
access points, and switch-related reports will be empty.
Q.
What are the extra inventories listed in the Run Now folder?
A.
The radio management module runs periodic immediate inventories.
Q.
What are the results of adding or removing an interface from an access point?
A.
If you physically remove an interface (for example, removing 11b from a
dual-interface AP 1200), the WLSE will automatically detect the change
during the next inventory cycle. If you physically add an interface, you must
delete the device and rediscover it. Otherwise, the inventory data might be
invalid.
Q.
Can the WLSE discover access points that are connected to non-Cisco
switches?
A.
The APs cannot be discovered through CDP, but you can import the APs from
a file or enter them all as seeds in the WLSE UI.
