Multiple RADIUS servers for Multiple subnets on same switch

[vaishalin]

Dear Team,

I have one switch with multiple LANs/VLANs.

My requirement is i want these LANs to be authenticated with three different servers with 802.1x.

On single switch what configuration can be made to point different servers for each VLAN.

Please suggest.

Regards

There's not a way that I'm aware of that would allow you to do this. The radius servers are defined locally, and in my testing, can hit any one of them. I use two servers for redundancy, and I've seen them both randomly be hit. My only suggestion would be make sure that you have the same database across radius servers so you can account for a user should they hit any one of the three servers that you have.

HTH,
John
