We're standing up a new network and I'm not having any luck getting Radius to work on my switches. It seems like the switch isn't even attempting to contact the Radius server, because when I attempt to ssh into the switch, then do a "show radius statistics", I don't see the counters incrementing at all. For example, there are counters for packets with and without responses, and both of them have been sitting at 0 ever since I installed the switch, even though I've tried several times to log in with my Radius credentials (my Windows AD login). The Radius config on my switch is as follows:
The following is the config I'm using on the switch:
aaa new-model
aaa authentication login RadiusGroup group radius local
aaa authorization exec RadiusGroup group radius local
!
username backup privilege 15 password xxx
!
ip domain-name xxxx.xxx.xxx
!
interface Vlan100
ip address x.x.x.x x.x.x.x
!
ip radius source-interface Vlan100
radius-server host x.x.x.x auth-port 1645 acct-port 1646 key xxxxx
radius-server retransmit 3
!
line vty 0 4
exec-timeout 15 0
authorization exec RadiusGroup
logging synchronous
transport input ssh
!
Any help is appreciated, thanks.
