Information
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 30, Port Monitoring.
permit tcp
c e s z
Configure a filter to pass TCP packets meeting the filter criteria.
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] | 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 or
• Use the no permit tcp {source mask | any | host ip-address} {destination mask | any |
host ip-address} command.
order (OPTIONAL) Enter the keyword order to specify the QoS priority for the ACL
entry.
Range: 0-254 (where 0 is the highest priority and 254 is the lowest; lower order
numbers have a higher priority)
Default: If the order keyword is not used, the ACLs have the lowest order by default
(255).
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.
fragments Enter the keyword fragments to use ACLs to control packet fragments.
Version 8.3.1.0
Added
dscp keyword.
Version 8.2.1.0 Allows ACL control of fragmented packets for IP (Layer 3) ACLs.
Version 8.1.1.0 Introduced on E-Series ExaScale
Version 7.4.1.0
Added support for non-contiguous mask and added the
monitor option.
Version 6.5.10
Expanded to include the optional QoS
order priority for the ACL entry.
Note: When ACL logging and byte counters are configured simultaneously, byte counters
may display an incorrect value. Configure packet counters with logging instead.
