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.
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.
ethertype
operator
(OPTIONAL) To filter based on protocol type, enter one of
the following Ethertypes:
• ev2 - is the Ethernet II frame format.
• llc - is the IEEE 802.3 frame format.
• snap - is the IEEE 802.3 SNAP frame format.
count (OPTIONAL) Enter the keyword count to count packets the
filter processes.
byte (OPTIONAL) Enter the keyword byte to count bytes the filter
processes.
log (OPTIONAL) Enter the keyword log to include ACL
messages in the log.
threshold-in
msgs count
(OPTIONAL) Enter the threshold-in-msgs keyword
followed by a value to indicate the maximum number of ACL
logs that can be generated, exceeding which the generation
of ACL logs is terminated with the seq, permit, or deny
commands. The threshold range is from 1 to 100.
