Configuration Commands
Description Configures matching on ICMP code field in the ICMP header of an IP packet as a filter match
criterion. Note that an entry containing L4 match criteria will not match non-initial (2nd, 3rd, etc)

This option is only meaningful if the protocol match criteria specifies ICMP (1).
The no form of the command removes the criterion from the match entry.
Default
no icmp-code
Parameters icmp-code — The ICMP code values that must be present to match.
