Command History Usage Information Version 8.2.1.0 Version 8.1.1.0 Version 7.4.1.0 Version 6.5.10 Allows ACL control of fragmented packets for IP (Layer 3) ACLs. Introduced on the E-Series ExaScale. Added the monitor option. Expanded to include the optional QoS order priority for the ACL entry. 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 Configuration Guide. NOTE: When ACL logging and byte counters are configured simultaneously, byte counters may display an incorrect value. Configure packet counters with logging instead. 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 flow-based monitoring only. For more information, refer to Port Monitoring. You cannot include IP, TCP, or UDP filters in an ACL configured with ARP filters. permit icmp Configure a filter to allow all or specific ICMP messages. E-Series 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: • Use the no seq sequence-number command if you know the filter's sequence number. • Use the no permit icmp {source mask | any | host ip-address} {destination mask | any | host ip-address} command. Parameters source mask any host ip-address destination Enter the IP address of the network or host from which the packets were sent. Enter a network mask in /prefix format (/x) or A.B.C.D. The mask, when specified in A.B.C.D format, may be either contiguous or noncontiguous. Enter the keyword any to match and drop specific Ethernet traffic on the interface. Enter the keyword host and then enter the IP address to specify a host IP address. Enter the IP address of the network or host to which the packets are sent. 268
