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 time 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 five minutes. By default,
flow-based monitoring is not enabled.

History
Version 9.5(0.1)
Introduced on the Z9500.
Version 9.4(0.0)
Added support for flow-based monitoring on the S4810,
S4820T, S6000, and Z9000 platforms.
Version 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
new interval commences from zero. If ACL logging was stopped previously
because the configured threshold is exceeded, it is re-enabled for this new interval.
If ACL logging is stopped because the configured threshold is exceeded, it is re-
enabled after the logging interval period elapses. ACL logging is supported for
standard and extended IPv4 ACLs, IPv6 ACLs, and MAC ACLs. You can configure
