6.5.10 Expanded to include the optional QoS order priority for the ACL entry.
Usage Information
The order option is relevant in the context of the Policy QoS feature only. For more information, refer to the
Quality of Service chapter of the FTOS Conguration Guide.
When you use the log option, the 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 ow-based monitoring only. For more information, refer to Port
Monitoring.
NOTE: When ACL logging and byte counters are congured simultaneously, byte counters may display
an incorrect value. Congure packet counters with logging instead.
permit tcp
To pass TCP packets meeting the lter criteria, congure a lter.
Syntax
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] [order] [fragments] [monitor [session-ID]] [no-drop]
