Wireless LAN Solution Engine: discover fails !!!

f49713 · ‎01-16-2004

I tried to discover 3550-Switche with our Cisco WLSE V2.5. Two 3550 devices working fine (V12.2.(8)EA1)+(V12.2.(9)EA1).

Other 3550 devices with V12.2.(13)EA1 didn't respond. I don't know why. (same config)

-I checked the SNMP-connection with the WLSE query

tool. Works fine!

-ACL ist activ but the WSLE IP-Address ist permited.

Works fine with two devices.

Thank you in advance

From your WLSE GUI, under Administration->Appliance->Connectivity Tools->Network Tools, run the SNMP Reachable Test for the device in question. If it fails with a timeout error etc, then we know that SNMP between the WLSE and this device is not working.

I checked the switch with the snmp query tool.(IP and hostname.domain-name) -works fine-.

All switches I'am interrested can be reached with the tool.cdp an snmp is enabled on all switches.

I discovered two switches:

Try increasing the CDP Distance/Hop Count in WLSE from 1 to 3 or 4 and then run the discovery again.
