I am trying to do a subnet discovery in IPAM on our Nexus 7700, but it doesn't seem to be working. I have confirmed I am able to make snmp queries to the Nexus from the IPAM host using the SNMPWalk tool. Whenever I do a subnet discovery, the discovery window pops up for about 3 seconsd and immediately goes to a screen that tells me 0 subnets have been found. Is there something I am doing wrong or is subnet discovery not possible on a Nexus?
