I am trying to set up Network Sonar Discoveries and when I try to add a Seed router (Cisco 6509-E runing L3) it says Error: unable to find subnets. THis is a node that is already in both NPM and NCM but I want to run regualar scans going forward and since we have a lot of networks I would prefer to use seed routers instead and individually typing out subnets.
I can run switch port mapper on this switch with no trouble.
