Discovery don't show cdp neighborship established between two Cisco switches

[Ivan Prikhodko]

Dear Experts,

Does anyone know what level of access and using which protocol (ssh, SNMP) I need to make it possible for Discovery get information about neighborship between Cisco switches (and other devices). For now, related list for neighbors is simply empty, while I have all bunch of information about two Cisco switches populated into CMDB.

I would much appreciate your idea and advises on this matter.

Ivan,

It uses SNMP access only.

How Layer 2 Discovery works

Did you ever find out more information on this? We are using SNMP but our discovery doesn't appear to be collecting the Cisco Discovery Protocol (CDP) data that it should be.

We had the same issue and opened a ticket for that.

When you go to the CI record there is a tab "Device Neighbors" where it shows the neighbors fund via CDP (so far so good).

When you want to "see" the relationships, you have to click on the "Show Dependency Views" button, go to the "Map Settings" and change the "Dependency Type" from "default" to "Physical Network Connection" and apply.

All already discovered neighbor CIs and their relation between them show up.

Hope that helps.
