CLI
– This shows that the entries in the mask override the precedence in
which the rules are entered into the ACL. In the following example,
packets with the source address 10.1.1.1 are dropped because the “deny
10.1.1.1 255.255.255.255” rule has the higher precedence according the
“mask host any” entry.
Configuring a MAC ACL Mask
This mask defines the fields to check in the packet header.

port.
