I have been having 2 issues, first the management IP was changing for my core switches everytime a data collection was done, this messed up, the 2 Core would be read and then the links to the edge devices also read. this is only happening on these 2 Core switches. I did the change management IP under tolopogy services but this didnt help. I still had the same issue. i rediscovered the network, still although the management IP was the right looopback IP i had configured, it still had the Core switches in Red.
Then, i think i did what i shouldnt have done, i right clicked the core switches and deleted them in topology services. i ran the data collection but nothing came up in the topology, restarted the processes,, still nothing. i have noted though, that all my devices are under the unconnected View, as reachable... there is nothing in Layer 2 view
So, how do i make sure that the i get back the layer 2 view, displaying my topology ? and, how do i make sure that the management IP doesnt change ?
Thanks in Advance
