MrpInTest¶

Namespace: inet

class MrpInTest

MRP_InTest: Periodically sent by the Media Redundancy Interconnection Manager (MIM) on both of its interconnection ports to check the integrity of the interconnection between the two MRP rings. These frames are circulated among all interconnected MIMs and MICs, and must be received back at the originating MIM to confirm the integrity of the interconnection.
