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 MAC ACL filter to drop packets.
seq — configure a MAC ACL filter with a specified sequence number.
seq
Configure a filter with a specific sequence number.
Z9000
Syntax
seq sequence-number {deny | permit} {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 delete a filter, use the no seq sequence-number command.
Parameters
sequence-
number
Enter a number as the filter sequence number. The range is from zero
(0) to 65535.
deny Enter the keyword deny to drop any traffic matching this filter.
permit Enter the keyword permit to forward any traffic matching this filter.
any Enter the keyword any to filter all packets.
host mac-
address
Enter the keyword host and then enter a MAC address to filter
packets with that host address.
mac-source-
address
Enter a MAC address in nn:nn:nn:nn:nn:nn format.
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.
