I've started having an odd issue with 802.1x authentication some new 4208vl's that we recently got. I'm pretty sure I narrowed the is down to the switch.
Essentially what is happening is that if I plug a single device into a switch port it will authenticate (works for mitel voip phones and XP with SP3). However if I connect a computer to the pass through port on the voip phone the computer will not authenticate but the phone does. It's almost like the switch is not paying attention to the client-limit setting.
In that scenario XP will say that authentication failed with an event ID 15514 in the event log (that event has a reason 327685). Googling has returned very little so far on reason 327685.
My dot1x config for the switch is setup as follows.
gvrp
aaa authentication port-access eap-radius
radius-server key mysecrete
radius-server host 10.x.y.z
aaa port-access gvrp-vlans
aaa port-access authenticator A1
aaa port-access authenticator A1 unauth-vid 12
aaa port-access authenticator A1 client-limit 3
aaa port-access authenticator active
aaa port-access A1
I've also ruled out the phones from this issue. I currently have a phone with attached computer connected to a 2650 without issue.
Anyone have any thoughts? Did I miss something simple in my config? Thanks in advance.
