Problem logging into switch using RADIUS authentication

[Vince Butler]

Figured out what it was! Turns out it was just a routing mistake on my part.

The 5400 at the District Office has a default route to a Cisco router, which is what all of our sites connect to via their T1's (except for the one school that has been giving me the problem, which is directly connected to the 5400 via fiber and routing via OSPF). All of the devices at the District Office use the Cisco router as their default gateway. The Cisco had a route for 10.2.0.0, forwarding that traffic to the 5400 which then forwarded on via OSPF.

The problem switch has two IP's assigned - a 10.2.x.x address for the local subnet and a 10.88.2.x address for the VLAN connecting it to the 5400. Traffic generated by the problem switch was using the 10.88 address, and when District Office devices received communication from the switch they were replying back to the 10.88 address via the Cisco gateway, which didn't have a route back to that network. I added one and now everything's peachy.

Closed, answer above.
