permit tcp (for IPv6 ACLs)Configure a filter to pass TCP packets that match the filter criteria.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’ssequence 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 triggeringof ACL log messages.threshold-inmsgs count(OPTIONAL) Enter the threshold-in-msgs keywordfollowed by a value to indicate the maximum number of ACLlogs that can be generated, exceeding which the generationof ACL logs is terminated. with the seq, permit, or denycommands. The threshold range is from 1 to 100.intervalminutes(OPTIONAL) Enter the keyword interval followed by thetime 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 isdescribing the traffic that you want to monitor and the ACLin which you are creating the rule is applied to the monitoredinterface.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.CommandModesACCESS-LISTCommandHistory 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.UsageInformationWhen the configured maximum threshold is exceeded, generation of logs isstopped. When the interval at which ACL logs are configured to be recordedexpires, the subsequent, fresh interval timer is started and the packet count for thatnew interval commences from zero. If ACL logging was stopped previouslybecause the configured threshold is exceeded, it is re-enabled for this new interval.Access Control Lists (ACL) 335
