permit (for Standard MAC ACLs)
To forward packets from a specific source MAC address, configure a filter.
Syntax permit {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 permit {any | mac-source-address mac-source-
address-mask} command.
Parameters 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
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 interval 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 5 minutes. By default,
flow-based monitoring is not enabled.
Command
History Version Description
9.7(0.0) Introduced on the S6000–ON.
9.4(0.0) Added support for flow-based monitoring on the S4810,
S4820T, S6000, and Z9000 platforms.
9.3(0.0) Added support for logging of ACLs on the S4810, S4820T,
and Z9000 platforms.
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 count for that
