Devices FAQs and Troubleshooting

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 manager automatically runs periodic inventories for relevant functionality.

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.You cannot use CDP to discover the APs, but you can import them from a file or enter them all as seed devices in the WLSE. Alternatively, if you have configured Wireless Domain Services, the APs may automatically be discovered if they are within the range of the participating APs.

Q.Can I register an access point as an AAA server to be monitored by the WLSE?

A.Yes, you can register an AP 1100 or AP 1210 as an AAA server. However, if you register an AP as an AAA server, you can no longer use the WLSE to manage that AP as a wireless device.

Q.How does the WLSE handle duplicate IP addresses on APs?

A.The WLSE must be able to handle situations in which an AP is assigned an address that is already assigned to another device that has been discovered by the WLSE. The WLSE handles these situations by sending appropriate internal events, placing the device that previously had the address in the Duplicate IP folder and updating the database. Detection of duplicate addresses occurs during periodic checking for rebooted APs and during discovery.

For information on how you should handle devices in the Duplicate IP folder, see the online help for the Devices tab or the section called “Handling Duplicate IP Addresses on Access Points” in the User Guide for the CiscoWorks Wireless LAN Solution Engine, Release 2.13 on Cisco.com.

Q.Will the WLSE discover a router or switch that has no access points connected to it?

A.The WLSE does not discover a router or switch that has no supported access point or bridge attached to it.
