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 you configure the ACL logging and byte counters simultaneously, byte counters may
display an incorrect value. Configure packet counters with logging instead.

Commands
• deny — configure a filter to drop packets.
• permit — configure 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 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 filter criteria, configure a filter.
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.
