Extended MAC ACL Commands
When an access-list is created without any rule and then applied to an interface, ACL behavior reflects
implicit permit. The following commands configure Extended MAC ACLs.
The Z9500 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 filter criteria, configure a filter.
Z9500
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 filter, you have two choices:
• Use the no seq sequence-number command if you know the filter’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
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.
