Description
This command is used to set the R-APS VLAN parameters. The ring_mel command is used to
configure the ring MEL for an R-APS VLAN. The ring MEL is one field in the R-APS PDU. Note that if
CFM (Connectivity Fault Management) and ERPS are used at the same time, R-APS PDU is one of a
suite of Ethernet OAM PDU. The behavior for forwarding of R-APS PDU should follow the Ethernet
OAM. If the ring MEL is not higher than the highest MEL of the MEPs on the ring ports, the R-APS
PDU cannot be forwarded on the ring.
The ring_port command is used to configure the port that participates in the ERPS ring. Restrictions
apply for ports that are included in a link aggregation group. A link aggregation group can be
configured as a ring port by specifying the master port of the link aggregation port. Only the master
port can be specified as a ring port. If the specified link aggregation group is eliminated, the master
port retains its ring port status. If the ring port is configured on a virtual channel, the ring that the port is
connected to will be considered as a sub-ring.
Note that modifying the ring port number may not take effect immediately when ERPS function is
enabled. The ring will run the old configuration's protocol if the follow conditions are not met:
1. The Ring port is a tagged member port of the R-APS VLAN.
2. The RPL port is not virtual channel.
3. The Ring port is the master port if it belongs to a link aggregation group.
The rpl command is used to configure the RPL port and the RPL owner.
1. RPL port - Specifies one of the R-APS VLAN ring ports as the RPL port. To remove an RPL
port from an R-APS VLAN, use the none designation for rpl_port.
2. RPL owner - Specifies the node as the RPL owner.
