host ipv6–
address
Enter the keyword host then the IPv6 address to specify a host IP address.
operator (OPTIONAL) Enter one of the following logical operand.
● eq = equal to
● neq = not equal to
● gt = greater than
● lt = less than
● range = inclusive range of ports (you must specify two ports for the port
command)
port Enter the application layer port number. Enter two port numbers if using the range
logical operand. The range is from 0 to 65535. The following list includes some
common TCP port numbers:
● 23 = Telnet
● 20 and 21 = FTP
● 25 = SMTP
● 169 = SNMP
count (OPTIONAL) Enter the keyword count to count the packets that filter the
processes.
byte (OPTIONAL) Enter the keyword byte to count the bytes that filter the processes.
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 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.
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.
