permit tcp (for IPv6 ACLs)
Configure a filter to pass TCP packets that match the filter criteria.
C9000 Series
Syntax
permit tcp {source address mask | any | host ipv6-address}
[operator port [port]] {destination address | any | host ipv6-
address} [bit] [operator port [port]] [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 tcp {source address mask | any | host ipv6-
address} {destination address | any | host ipv6-address}
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.
