IP (v4/v6) Filter Entry Commands
eq — Specifies the operator to use relative to dst-port-number for specifying the port number match
dst-port-number — The destination port number to be used as a match criteria expressed as a decimal
range start end — Specifies an inclusive range of port numbers to be used as a match criteria. The
fragment
Syntax
IPv4:
fragment {true|false}
no fragment
IPv6:
fragment {true|false|first-only|non-first-only}
no fragment
config>filter>ip-filter>entry>match
Context
config>filter>ipv6-filter>entry>match
This command specifies fragmented or non-fragmented IP packets as an IP filter match criterion.
Description
Note that an entry containing Layer 4 match criteria will not match non-initial (2nd, 3rd, etc)
fragments of a fragmented packet since only the first fragment contains the Layer 4 information.
This command enables match on existence of IPv6 Fragmentation Extension Header in the IPv6 filter
policy. To match first fragment of an IP fragmented packet, specify additional Layer 4 matching
criteria in a filter policy entry. The no version of this command ignores IPv6 Fragmentation
Extension Header presence/absence in a packet when evaluating match criteria of a given filter policy
entry.
The no form of the command removes the match criterion.
Default
no fragment
true — Specifies to match on all fragmented IP packets. A match will occur for all packets that have
Parameters
false — Specifies to match on all non-fragmented IP packets. Non-fragmented IP packets are packets
first-only — For IPv6: Matches if a packet is an initial fragment of the fragmented IPv6 packet.
non-first-only — For IPv6: Matches if a packet is a non-initial fragment of the fragmented IPv6
