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 dscp message-type count byte log order 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. Enter the keyword dscp to deny a packet based on the DSCP value. The range is 0 to 63. (OPTIONAL) Enter an ICMP message type, either with the type (and code, if necessary) numbers or with the name of the message type. The range is 0 to 255 for ICMP type and 0 to 255 for ICMP code. (OPTIONAL) Enter the keyword count to count packets the filter processes. (OPTIONAL) Enter the keyword byte to count bytes the filter processes. (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. The range is 0 to 254 (where 0 is the highest priority and 254 is the lowest; lower-order numbers have a higher priority). If you do not use the keyword order, the ACLs have the lowest order by default (255). 247
