Information
The C-Series cannot count both packets and bytes, so when you enter the count byte options,
only bytes are incremented.
permit tcp
c e s
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] [monitor]
To remove this filter, you have two choices:
• Use the
no seq sequence-number command syntax if you know the filter’s
sequence number or
• 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 have the information kept in an
ACL log file.
monitor
(OPTIONAL) Enter the keyword monitor to monitor traffic on the
monitoring interface specified in the flow-based monitoring session
along with the filter operation.
