Hello,
we have a network with about 200 2920-48 PoE switches running well. We have enabled MAC-Authentication against Windows NPS. This is working for the most of our devices.
But some of them are unable to authenticate. The Problem is, i cant see anything in the Aruba LOGs. No request is reaching the NPS. No MAC-Address is shown on the Switchport. If i disable MAC-Auth the device gets active.
The config looks like:
interface 1/xx
untagged vlan 11xx
aaa port-access mac-based
aaa port-access mac-based unauth-vid 1
loop-protect
exit
As i said, most of our devices (where we use MAC-Based authentication) are working well. They get authenticated by the NPS.
Any ideas ?
Thanks,
Ralph
