deny icmp To drop all or specific internet control message protocol (ICMP) messages, configure a filter. C9000 Series Syntax deny icmp {source-ip-address mask | any | host ip-address} {destination mask | any | host ip-address} [log] [dscp] [[count [bytes]] [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 deny icmp {source-ip-address mask | any | host ipaddress} {destination mask | any | host ip-address} command. Parameters source-ip-address Enter the IP address of the network or host from which the packets were sent. mask 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. any Enter the keyword any to specify that all routes are subject to the filter. host ip-address Enter the keyword host then the IP address to specify a host IP address. destination Enter the IP address of the network or host to which the packets are sent. log (OPTIONAL) Enter the keyword log to include ACL matches in the log. dscp Enter this keyword dscp to deny a packet based on the DSCP value. The range is from 0 to 63. count (OPTIONAL) Enter the keyword count to count packets processed by the filter. bytes (OPTIONAL) Enter the keyword bytes to count bytes processed by the filter. order (OPTIONAL) Enter the keyword order to specify the QoS priority for the ACL entry. The range is from 0 to 254 (where 0 is the highest priority and 254 is the lowest; lower order numbers have a higher priority) If you did not use the keyword order, the ACLs have the lowest order by default (255).
