CLI Guide

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.
