Hi, I've got som issues concering an ESW 520 Switch - we need to use Mac Auth Bypass (only) but it seems that it won't work!
Only works when you apply 802.1x!!
Hi Lin Lundh,
The IEEE 802.1X standard and MAC Auth Bypass allows the dynamic configuration of access ports as well as implementing the corporate security
policy on the port level.MAB functions as a port-based feature. It is primarily used as a fallback mechanism to 802.1X, although it is optionally available as a stand-alone authentication method with CatOS.MAB provides customers who do not or cannot do 802.1X, but who also want port security with configured MAC addresses, with more options, and also provides a migration path to customers running URT or VMPS technologies. MAB also works with any standard RADIUS server, with a default timeout of 30 seconds with three retries.
