COMMAND USAGE
â—† 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.
â—† 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 domain command
will be used in R-APS PDUs.

COMMAND MODE
ERPS Configuration
COMMAND USAGE
â—† Configure one control VLAN for each ERPS ring. First create the VLAN to
be used as the control VLAN (vlan, page 1124), add the ring ports for
the east and west interface as tagged members to this VLAN
(switchport allowed vlan, page 1126), and then use the control-vlan
command to add it to the ring.
â—† The following restrictions are recommended to avoid creating a loop in
the network or other problems which may occur under some situations:
â–
The Control VLAN must not be configured as a Layer 3 interface
(with an IP address), a dynamic VLAN (with GVRP enabled), nor as
a private VLAN.
â–
In addition, only ring ports may be added to the Control VLAN. No
other ports can be members of this VLAN.
â–
Also, the ring ports of the Control VLAN must be tagged.
