Cisco switches configured with SNMP v3 are not displaying connections.

There is a known issue with Cisco switches configured to SNMP v3 where they are not able to display the connections between devices.

This is due to Cisco disabling the display in their SNMP v3 protocol. 

The resolution for this issue is to either add SSH credentials to UVexplorer for the Cisco switches. The SSH credentials will be able to provide the full forwarding information for the device. 

Another alternative is to configure SNMPv2 on the Cisco switches and add the SNMPv2 credentials to UVexplorer.

Each of these resolutions will provide a detailed map of your network.
