Usage
Information
When you use the log option, the CP processor logs details about the packets that match.
Depending on how many packets match the log entry and at what rate, the CP may become
busy as it has to log these packets’ details.
NOTE: When ACL logging and byte counters are configured simultaneously, byte counters
may display an incorrect value. Configure packet counters with logging instead.

Commands
deny — configures a filter to drop packets.
permit — configures a filter to forward packets.
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 Z9000 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.
Z9000
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] [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.
