Hi All,
Would very much appreciate any feedback or suggestions on the following. I have a C25 and LPA successfully managed in NetSight via SNMPv3. What I am trying to do is create a single NAC VNS that allows access for Authenticated and Unauthenticated, (Guest) devices.
802.1x authenticated users connect to the VNS and can be remediated, no problem.
Unauthenticated users should connect to the VNS and then find themselves directed to NAC's login page when they open a browser. I am seeing in NAC that the connection attempt is, "Accept", but MAC-to-IP Address resolution fails. There are ip helper-addresses on the relevant Core switches VLAN GW that point to the DHCP server, the Layer-3 interface created for the NAC VNS and even the management IP address of the Controller.
I've set debugging for DHCP, IP resolution and SNMP to Verbose and in the tag.log and I am seeing the following error...
DEBUG [SnmpManager] Unable to get SnmpSwitch for IP: 127.0.0.1 sw: null
Has anybody seen this error before and/ or are there any suggestions on what might be causing it?
Kind regards,
Simon Read
