mac acl on native vlan (trunk port)?

Hi there

How can this be achieved?

E.g. an MAC-ACL on a trunk where an accesspoint is connected. So, that only a defined MAC (AP) is allowed to connect through the native VLAN.

Thanks,

Norbert

Hi,

you can configure port-security on a trunk port per vlan but the port must be an unconditional port( the output from operational and administrative mode must be trunk in sh int switchport command).

Hi,

you can't use a MAC ACL as it only works for non IP traffic but you  can use port security( for Vlan 1) as long as the port is an unconditional trunk( switchport mode trunk).

Hi,

Thanks for the reply.

I'll get a try on my lab, but I've found this.

..Cisco does not allow you to configure port security in trunk ports cause trunk ports may learn many mac addresses which will defeat the use of port security feature...

Hi,

I tried the configuration on a trunk port with an access point. The problem is, that the roaming doesn't work with a couple of access points.
