deny
To drop packets with a the MAC address specified, configure a filter.
Syntax
deny {any | mac-source-address [mac-source-address-mask]} [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 | mac-source-address mac-source-address-mask} command.
Parameters
any Enter the keyword any to specify that all routes are subject to the filter.
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).
count (OPTIONAL) Enter the keyword count to count packets processed by the filter.
byte (OPTIONAL) Enter the keyword byte to count bytes processed by the filter.
log (OPTIONAL) Enter the keywordlog to enable the triggering of ACL log messages.
threshold-in-msgs
count
(OPTIONAL) Enter thethreshold-in-msgs keyword followed by a value to indicate
the maximum number of ACL logs that can be generated, exceeding which the
generation of ACL logs is terminated. with the seq, permit, or deny commands. The
threshold range is from 1 to 100.
interval minutes (OPTIONAL) Enter the keyword interval followed by the time period in minutes at
which ACL logs must be generated. The threshold range is from 1 to 10 minutes.
monitor (OPTIONAL) Enter the keyword monitor when the rule is describing the traffic that
you want to monitor and the ACL in which you are creating the rule is applied to the
monitored interface.
Defaults 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.

Version Description
9.9(0.0) Introduced on the FN IOM.
9.4(0.0) Added support for flow-based monitoring on the MXL 10/40GbE Switch IO Module
platform.
9.3(0.0) Added support for logging of ACLs on the MXL 10/40GbE Switch IO Module platform.
8.3.16.1 Introduced on the MXL 10/40GbE Switch IO Module platform.
Usage Information
When the configured maximum threshold is exceeded, generation of logs is stopped. When the interval at which
ACL logs are configured to be recorded expires, the subsequent, fresh interval timer is started and the packet
