• mac access-list standard — congure a standard MAC access list.
• show mac accounting access-list — display MAC access list congurations and counters (if congured).
permit
To pass packets matching the criteria specied, congure a lter.
Syntax
permit {any | host mac-address | mac-source-address mac-source-address-mask}
{any | host mac-address | mac-destination-address mac-destination-address-mask}
[ethertype operator] [count [byte]] | [log] [monitor]
To remove this lter, you have two choices:
• Use the no seq sequence-number command if you know the lter’s sequence number.
•
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 ::::: 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 ::::: 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 lter 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 lter processes.
byte (OPTIONAL) Enter the keyword byte to count bytes the lter processes.
log (OPTIONAL, E-Series only) Enter the keyword log to log the packets.
monitor (OPTIONAL) Enter the keyword monitor when the rule is describing the trac that you
want to monitor and the ACL in which you are creating the rule is applied to the
monitored interface.
