no src-port
Context config>filter>ip-filter>entry>match
Description
This command configures a source TCP or UDP port number or port range for an IP filter match

fragments of a fragmented packet since only the first fragment contains the L4 information.
The no form of the command removes the source port match criterion.
Default
no src-port
Parameters
lt | gt | eq — Specifies the operator to use relative to src-port-number for specifying the port number
src-port-number — The source port number to be used as a match criteria expressed as a decimal
