auth-proxy with RADIUS on 3750

[jobrien9291]

I'm trying to set up auth-proxy on a 3750 running 12.5(55). The config seems to proceed normally until I try to configure the interface itself. I get this:

colo2-sw(config)#int vlan6
colo2-sw(config-if)#ip auth-proxy PROX_NAME
% This config is not supported on this platform. Try configuring a new rule.

I found an old post with the same issue and the last entry was:

"answer from Cisco: webauth or auth-proxy supported only via RADIUS or TACACs.

Not supported via local authentication ...."

...but I am using RADIUS

aaa authentication login default group WINDOWS-RADIUS local
aaa authorization auth-proxy default group radius
aaa accounting auth-proxy default start-stop group radius

If anyone knows what the magic is to get this to work I'd sure like to hear it.

Thanks.
