•
Source MAC Address:
-
MAC Addres
are addressed to the ACE.
-
Wildcard Mask
Wildcards are used to mask all or part of a source MAC Address.
Wildcard masks specify which octets are used and which octets are
ignored. A wildcard 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.

Wildcard Mask
mask. Wildcards are used to mask all or part of a destination MAC
