Information
The monitor option is relevant in the context of flow-based monitoring only. See Chapter 46, Port
Monitoring.
The order option is relevant in the context of the Policy QoS feature only. The following applies:
• The seq sequence-number is applicable only in an ACL group.
• The order option works across ACL groups that have been applied on an interface via QoS policy
framework.
• The order option takes precedence over the seq sequence-number.
•If sequence-number is not configured, then rules with the same order value are ordered
according to their configuration order.
•If the sequence-number is configured, then the sequence-number is used as a tie breaker for
rules with the same order.
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.
host ip-address
Enter the keyword host followed by the IP address to specify a host IP address or
hostname.
count (OPTIONAL) Enter the keyword count to count packets processed by the filter.
byte (OPTIONAL) Enter the keyword byte to count bytes processed by the filter.
log (OPTIONAL, E-Series only) Enter the keyword log to enter ACL matches in the log.
dscp (OPTIONAL) Enter the keyword dcsp to match to the IP DCSCP values.
order (OPTIONAL) Enter the keyword order to specify the QoS order 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 when the rule is describing the traffic that
you want to monitor and the ACL in which you are creating the rule will be applied to
the monitored interface. For details, see the section “Flow-based Monitoring” in the
Port Monitoring chapter of the FTOS Configuration Guide.
fragments Enter the keyword fragments to use ACLs to control packet fragments.
Version 8.3.1.0 Add DSCP value for ACL matching.
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 7.6.1.0 Added support for S-Series
Version 7.5.1.0 Added support for C-Series
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.
