caAclIPV4ACESourcePortOperator
1.3.6.1.4.1.9.9.808.1.1.2.1.7
This object defines the operation to be performed to the layer
source port field. Source port fields are present only for
IGMP, ICMP, SCTP, TCP, and UDP protocols.
If caAclIPV4ACEProtocol is none of the ones listed above, this
field should set to noOperator(1), which means not comparison
is to be performed.
If this field is set to range(5) then two port numbers are
necessary. I.e., Both caAclIPV4ACESourcePort and
caAclIPV4ACESourcePortUpper need to be provided.
