Authentication MAC using ACS

ariantow123 — Sun, 10 Mar 2019 23:12:12 GMT

hi,

I need some help to implement authentication of device's MAC Address (PC, laptop, IP Phone, printer) using ACS.

My goal is to create VMPS like, but using ACS as authenticator of any devices connect to the network.

Just connect devices to the network, and based on MAC address ACS define the proper VLAN.

I'm using ACS for Windows v4.1 and catalyst 2950(WS-2950T-24) 12.1-22 EA12.

thanks for any respond.

You may want to consult a 802.1x guide...

We use ACS to authenticate wireless users through MAC method.

I guess same principle applies.

What you do is create internal ACS user accounts using the MAC address as username AND password.

For some reason our deployment only works w/ lower case letters and not capital ones.

hi,

Yes you're correct.

I have read this (dot1x) article too.

For development and test I used wired PC. And it seem doesn't support for dot1x.

Another solution using MAB, but the switch doesn't support for the command ..

thx

We don't do wired dot1x, but for our WLAN, one thing our techs overlook is in the Authentication tab of the LAN properties window, they forgot to check "Enable dot1x", and/or define the EAP type correctly. (PEAP in our case)
