Configure Details
◆
Domain Name – Name of a configured ERPS ring. (Range: 1-12 characters)
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. Up to 6 ERPS rings
can be configured on the switch.
◆
Domain ID – ERPS ring identifier used in R-APS messages. (Range: 1-255;
Default: None)
R-A PS 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 for the R-APS Def MAC parameter, then the
Domain ID will be used in R-APS PDUs.
◆
Admin Status – Activates the current ERPS ring. (Default: Disabled)
Before enabling a ring, the global ERPS function should be enabled see (“ERPS
Global Configuration” on page 412), the east and west ring ports configured on
each node, the RPL owner specified, and the control VLAN configured.
Once enabled, the RPL owner node and non-owner node state machines will
start, and the ring will enter idle state if no signal failures are detected.
