Figure 7-10. Add ACE to MAC Based ACL
The
Add ACE to MAC Based ACL
page contains the following fields:
ACL Name
— User-defined ACL.
New ACE Priority
— ACE priority, which determines which ACE is matched to a packet on a first-
match basis.
Source MAC Address
—Matches the source MAC address from which packets are addressed to the
ACE.
Wild Card Mask
— The source MAC address wildcard mask. Wild cards are used to mask all or
part of a source MAC address. Wild card masks specify which bits are used and which bits are
ignored. A wild card mask of FF:FF:FF:FF:FF:FF indicates that no bit is important. A wildcard of
00.00.00.00.00.00 indicates that all the bits are important.
For example, if the source MAC address E0:3B:4A:C2:CA:E2 and the wildcard mask is
00:3B:4A:C2:CA:FF, the first two bits of the MAC are used, while the last two bits are ignored.
Destination MAC Address
— Matches the destination MAC address to which packets are
addressed to the ACE.
Wild Card Mask
— The destination MAC address wildcard mask. Wild cards are used to mask all
or part of a destination MAC address.
