I have rebuilt a SW server and added my devices using auto discover. I have configured a map using Network atlas by dragging and dropping the required devices onto the map. I tried linking the devices using the Connect Now feature but some of the devices will not connect automatically so I have manually linked the interfaces on the devices using the straight line tool provided. The link created auto changes to a red dotted line showing that it is down, the SW documentation states "A Red dashed line means that the Topology Calculator was unable to produce a connection drawn on the map. The drawn connection does not exist between nodes or there are not enabled Topology pollers on these nodes".
I have checked that there is a connection between these devices and it is UP. I have re-managed and rediscovered the devices but no joy. I then used the SW Orion Universal Device poller to try and updated the Topology pollers for the devices. One of the devices (Cisco ASA) shows an error "OID is not supported", this device and links was previously managed on the old system ?.
Any ideas how I can get these device links to display properly. The devices themselves are displaying ok ?
