I am using CISCOWORKS Campus Manager 3.3 and recently having a discovering issue with one device on the network.
when I go to campus manager-> topology services-> network views-> layer2 view and click on display view, one 6503 switch is not appearing on that. It was appearing previously and this happened after restarting the switch. But this switch is operational and didn't do any configuration changes on it.
I did following troubleshooting steps on the switch device.
1. Verified if CDP is enabled on the missing device.
2. Verified that it listed using the show cdp neighbor command on the neighboring device.
3. Verified that the remote IP address is correct in the neighbor device.
4. device is not listed in the Campus Manager -> Topology Services -> Network Views -> Unconnected Devices View.
Further some links between devices in the layer 2 view are also breaking in between and intermediately connecting to a horizontal line called "Ethernet 1000m"
Kindly help me to get this resolved.
