My client using 2 x 6509 connecting through a layer-2 WAN link, the ISP company has restricted there are only 100 mac-address in that link.
My client recently has added more PC in the network and end up there are more than 100 mac-address in the links. My client would like to deny some PCs to pass through that layer-2 link.
Can I use Mac ACL to filter these MAC to 'outgoing' through that physical interface port? Or other way to do it?
Thanks in advance.
