MAC Addres

to the ACE.
–
Wild Card Mask
— Indicates the source MAC Address wild card mask. Wildcards are
used to mask all or part of a source MAC Address. Wild card masks specify which
octets are used and which octets are ignored. A wild card mask of ff: ff:ff:ff:ff:ff
indicates that no octet is important. A wildcard of 00:00:00:00:00:00 indicates that all
the octets are important. For example, if the source MAC address 09:00:07:A9:B2:EB
and the wildcard mask is 00:ff:00:ff:00:ff, the 1st, 3rd, and 5th octets of the MAC
address are checked, while the 2nd, 4th, and 6th octets are ignored.

to the ACE.
–
