Concept Guide

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 match.

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 processed by the lter.
byte (OPTIONAL) Enter the keyword byte to count bytes processed by the lter.
Defaults Not congured.

Command History
Version Description
9.9(0.0) Introduced on the FN IOM.
8.3.16.1 Introduced on the MXL 10/40GbE Switch IO Module.
Related Commands
permit — congures a MAC address lter to pass packets.
seq — congures a MAC address lter with a specied sequence number.
deny
To drop packets with a the MAC address specied, congure a lter.
Syntax
deny {any | mac-source-address [mac-source-address-mask]} [count [byte]] [log
[interval minutes] [threshold—in-msgs [count]] [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 deny {any | mac-source-address mac-source-address-mask} command.
Parameters
any Enter the keyword any to specify that all routes are subject to the lter.
