Information
The monitor option is relevant in the context of flow-based monitoring only. See Chapter 44, 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.

Commands
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 Dell
Networking OS 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 7.4.1.0
Added support for non-contiguous mask and added the
monitor option.

permit Configure a filter to forward packets.
seq Assign a sequence number to a deny or permit filter in an IP access list while creating the
filter.
