Command Usage
◆ Service Instances within each ring are based on a unique maintenance
association for the specific users, distinguished by the ring name, maintenance
level, maintenance association’s name, and assigned VLAN. The maximum
number of ERPS instances that can be configured on the switch is equal to the
total number of physical ports.
◆ R-APS information is carried in an R-APS PDUs. The last octet of the MAC
address is designated as the Ring ID (01-19-A7-00-00-[Ring ID]). If use of the
default MAC address is disabled with the no raps-def-mac command, then the
Ring ID configured by the erps instance command will be used in R-APS PDUs.
◆ You must disable a running instance before modifying a Ring ID.
