Reference Guide

• Use the no permit {any | host mac-address | mac-source-address
mac-source-address-mask} {any | mac-destination-address mac-
destination-address-mask} command.
Parameters
any Enter the keyword any to forward all packets.
host Enter the keyword host then a MAC address to forward
packets with that host address.
mac-source-
address
Enter a MAC address in nn:nn:nn:nn:nn:nn format.
mac-source-
address-mask
(OPTIONAL) Specify which bits in the MAC address must
match.
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-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.
