Description: The internal port number. A value of 0 is a wildcard.

This object is used as input to a request for establishing a policy rule as well as for indicating the properties of an established policy rule. It is relevant to the operation of the MIDCOM-MIB implementation only if the value of object midcomTransportProtocol in the same entry has a value other than 0.

If object midcomRuleOperStatus of the same entry has the value newEntry(1) or setting(2), then this object can be written by a manager in order to specify the internal port number for which a reserve policy rule or an enable policy rule is requested to be established. Writing to this object in any state other than newEntry(1) or setting(2) will always fail with an 'inconsistentValue' error.

Note that this error code is SNMP specific. If the MIB module is used with other protocols than SNMP, errors with similar semantics specific to those protocols should be returned.

If object midcomRuleOperStatus of the same entry has the value reserved(7) or enabled(8), then this object will have the value that it had before the transition to this state.

If object midcomRuleOperStatus of the same entry has a value other than newEntry(1), setting(2), reserved(7), or enabled(8), then the value of this object is irrelevant.
