Extended MAC ACL Commands
When an access-list is created without any rule and then applied to an interface, ACL behavior reects implicit permit. The following
commands congure Extended MAC ACLs.
The platform supports both Ingress and Egress MAC ACLs.
NOTE: For more information, also refer to the Commands Common to all ACL Types and Common MAC Access List Commands
sections.
deny
To drop packets that match the lter criteria, congure a lter.
Syntax
deny {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 [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 | host mac-address | mac-source-address mac-source-
address-mask} {any | host mac-address | mac-destination-address mac-
destination-address-mask} command.
Parameters
any Enter the keyword any to drop all packets.
host mac-address Enter the keyword host and then enter a MAC address to drop packets with that host
address.
mac-source-
address
Enter a MAC address in nn:nn:nn:nn:nn:nn format.
mac-source-
address-mask
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 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.
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
