Access Control Lists (ACL)
Version 7.4.1.0
Added support for non-contiguous mask and added the
Version 6.5.10
Expanded to include the optional QoS
The order option is relevant in the context of the Policy QoS feature only. See the "Quality of
Service" chapter of the FTOS Configuration Guide for more information.
When you use the log option, CP processor logs details about the packets that match. Depending on
how many packets match the log entry and at what rate, the CP may become busy as it has to log these
packets' details.
The monitor option is relevant in the context of the flow-based monitoring feature only. See
Chapter 44, Port
Monitoring.
Note:
When ACL logging and byte counters are configured simultaneously, byte counters
may display an incorrect value. Configure packet counters with logging instead.
Configure a filter to pass TCP packets meeting the filter criteria.
permit tcp {source mask | any | host ip-address} [bit] [operator port [port]] {destination mask
| any | host ip-address} [bit] [dscp] [operator port [port]] [count [byte] | log] [order] [monitor]
[fragments]
To remove this filter, you have two choices:
Use the no seq sequence-number command syntax if you know the filter's sequence number
•
