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
} [

[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.
