Information
The order option is relevant in the context of the Policy QoS feature only. Refer to 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. Refer to the Port Monitoring chapter.
You cannot include IP, TCP or UDP filters in an ACL configured with ARP filters.
permit icmp
e
Configure a filter to allow all or specific ICMP messages.
Syntax
permit icmp {source mask | any | host ip-address} {destination mask | any | host
ip-address} [dscp] [message-type] [count [byte] | log] [order] [monitor] [fragments]
To remove this filter, you have two choices:
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 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,
refer to the section “Flow-based Monitoring” in the Port Monitoring
chapter of the FTOS Configuration Guide.
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
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.
