www.dell.com | support.dell.com deny icmp e Configure a filter to drop all or specific ICMP messages. Syntax deny 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 syntax if you know the filter's sequence number or • Use the no deny icmp {source mask | any | host ip-address} {destination mask | any | host ip-address} command. Parameters 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 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. Enter the keyword fragments to use ACLs to control packet fragments.
