Instances

An ERPS ring supports multiple ERPS instances. An ERPS instance is a logical ring to process service and protocol packets. Each ERPS instance has its own owner node and maintains its own state and data. An ERPS instance is uniquely identified by the ring ID and VLAN ID of ERPS packets. The ring ID indicates the ring of ERPS packets. It can be represented by the last byte in the destination MAC address of the packets. The VLAN ID indicates the ERPS instance of the packets.
