The value of tmnxMobGwSysGroupRowStatus specifies the row status
of this entry. It is used for the creation and deletion of this system
group.
In order for the row creation to succeed, values for
tmnxMobGwSysGroupRed and tmnxMobGwSysGroupGateway must be included in
the same SNMP SET PDU as tmnxMobGwSysGroupRowStatus. Otherwise,
the SET request will fail with an 'inconsistentValue' error.
