Parameters • Use the no permit icmp {source mask | any | host ip-address} {destination mask | any | host ip-address} command. source mask any host ip-address destination dscp message-type count byte log order monitor fragments 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 non-contiguous. Enter the keyword any to specify that all routes are subject to the filter. Enter the keyword host followed by the IP address to specify a host IP address. Enter the IP address of the network or host to which the packets are sent. Enter this keyword to deny a packet based on DSCP value. Range: 0-63 (OPTIONAL) Enter an ICMP message type, either with the type (and code, if necessary) numbers or with the name of the message type (ICMP message types are listed in Table 7-2). Range: 0 to 255 for ICMP type; 0 to 255 for ICMP code (OPTIONAL) Enter the keyword count to count packets processed by the filter. (OPTIONAL) Enter the keyword byte to count bytes processed by the filter. (OPTIONAL, E-Series only) Enter the keyword log to have the information kept in an ACL log file. (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). (OPTIONAL) Enter the keyword monitor to monitor traffic on the monitoring interface specified in the flow-based monitoring session along with the filter operation. Enter the keyword fragments to use ACLs to control packet fragments. Defaults Command Modes Command History Not configured CONFIGURATION-STANDARD-ACCESS-LIST Version 8.3.1.0 Version 8.2.1.0 Version 8.1.1.0 Version 7.4.1.0 Version 6.5.10 Added dscp keyword. Allows ACL control of fragmented packets for IP (Layer 3) ACLs. Introduced on E-Series ExaScale Added support for non-contiguous mask and added the monitor option. Expanded to include the optional QoS order priority for the ACL entry. Usage The order option is relevant in the context of the Policy QoS feature only. See the "Quality of Service" Information 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. Access Control Lists (ACL) | 207
