byte counters may display an incorrect value. Configure packet counters with
logging instead.

Parameters
sequence-
number
Enter a number as the filter sequence number. The range is
from zero (0) to 65535.
deny Enter the keyword deny to drop any traffic matching this
filter.
permit Enter the keyword permit to forward any traffic matching
this filter.
any Enter the keyword any to filter all packets.
host mac-address Enter the keyword host and then enter a MAC address to
filter packets with that host address.
mac-source-
address
Enter a MAC address in nn:nn:nn:nn:nn:nn format.
The MAC ACL supports an inverse mask; therefore, a mask
of ff:ff:ff:ff:ff:ff allows entries that do not match and a mask
of 00:00:00:00:00:00 only allows entries that match
exactly.
mac-source-
address-mask
Specify which bits in the MAC address must be matched.
mac-destination-
address
Enter the destination MAC address and mask in
nn:nn:nn:nn:nn:nn format.
mac-destination-
address-mask
Specify which bits in the MAC address must be matched.
