Syntax option-present {true | false}
no option-present
Context config>system>security>cpm-filter>ip-filter>entry>match
Description This command configures matching packets that contain the option field or have an option field of 0
in the IP header as an IP filter match criterion.
The no form of the command removes the checking of the option field in the IP header as a match
criterion.
This command applies to IPv4 filters only.
Parameters true — specifies matching on all IP packets that contain the option field in the header. A match
will occur for all packets that have the option field present. An option field of 0 is considered
as no option present.
false — specifies matching on IP packets that do not have any option field present in the IP header
(an option field of 0)

Syntax src-ip {ip-address/mask | ip-address netmask}
no src-ip
