Context config>system>security>cpm-filter>ip-filter>entry>match
Description
This command configures fragmented or non-fragmented IP packets as an IP filter match criterion.
The no form of the command removes the match criterion.
This command applies to IPv4 filters only.
Default
false
Parameters
true — configures a match on all fragmented IP packets. A match will occur for all packets that
have either the MF (more fragment) bit set or have the Fragment Offset field of the IP header
set to a non-zero value.
false — configures a match on all non-fragmented IP packets. Non-fragmented IP packets are
packets that have the MF bit set to zero and have the Fragment Offset field also set to zero.

The no form of the command removes the criterion from the match entry.
Default
no icmp-code
Parameters
icmp-code — specifies the ICMP code values that must be present to match
Values

binary – DHB)
