When ring nodes running ERPSv1 and ERPSv2 co-exist on the same
•
ring, the Ring ID of each ring node must be configured as "1".
•
If this command is disabled, the following strings are used as the node
identifier:
ERPSv1: 01-19-A7-00-00-01
•
ERPSv2: 01-19-A7-00-00-[Ring ID]

This command terminates the R-APS channel at the primary ring to sub-

A sub-ring may be attached to a primary ring with or without a virtual
•
channel. A virtual channel is used to connect two interconnection points
on the sub-ring, tunneling R-APS control messages across an arbitrary
Ethernet network topology. If a virtual channel is not used to cross the
intermediate Ethernet network, data in the traffic channel will still flow
across the network, but the all R-APS messages will be terminated at
the interconnection points.
Sub-ring with R-APS Virtual Channel – When using a virtual channel to
•
tunnel R-APS messages between interconnection points on a sub-ring,
the R-APS virtual channel may or may not follow the same path as the
traffic channel over the network. R-APS messages that are forwarded
