Usage Information
When you use the log option, the CP processor logs detail 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 packet details.
By default, 10 ACL logs are generated if you do not specify the threshold explicitly.
The default frequency at which ACL logs are generated is five minutes. By default,
flow-based monitoring is not enabled.
Use the monitor option only when you are using flow-based monitoring. For
more information, refer to the Port Monitoring chapter in the C9000 Series
Configuration Guide.
NOTE: When ACL logging and byte counters are configured simultaneously,
byte counters may display an incorrect value. Configure packet counters with
logging instead.

seq
To a deny or permit filter in a MAC access list while creating the filter, assign a sequence number.
C9000 Series
Syntax
seq sequence-number {deny | permit} {any | mac-source-address
[mac-source-address-mask]} [count [byte]] [log [interval
minutes] [threshold-in-msgs [count]] [monitor]
To remove this filter, use the no seq sequence-number command.
Parameters
sequence-
number
Enter a number from 0 to 65535.
deny Enter the keyword deny to configure a filter to drop packets
meeting this condition.
permit Enter the keyword permit to configure a filter to forward
packets meeting this criteria.
any Enter the keyword any to filter all packets.
mac-source-
address
Enter a MAC address in nn:nn:nn:nn:nn:nn format.
mac-source-
address-mask
(OPTIONAL) Specify which bits in the MAC address must
match. If no mask is specified, a mask of 00:00:00:00:00:00
is applied (in other words, the filter allows only MAC
addresses that match).
