• permit
• seq
deny
c e s
Configure a filter to drop packets that match the filter criteria.

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] [order] [monitor]] [log] [monitor]

the traffic that you want to monitor and the ACL in which you are
creating the rule will be applied to the monitored interface. For details,
