• seq — configure a MAC address filter with a specified sequence number.
deny (for Extended MAC ACLs)
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.
• 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.

log (OPTIONAL) Enter the keyword log to enable the triggering
of ACL log messages.
threshold-in msgs
count
(OPTIONAL) Enter the threshold-in-msgs keyword
