RRPP Configuration Commands
1-7
Parameters
ring-id: Ethernet ring network ID, in the range of 1 to 64.
master: Defines the current switch as the master node on the Ethernet ring network.
transit: Defines the current switch as the transit node on the Ethernet ring network.
primary-port pri-port: Specifies a primary port.
secondary-port sec-port: Specifies a secondary port.
level-value: RRPP ring level, 0 for primary ring and 1 for secondary ring.
edge: Specifies the current switch as an edge node on the Ethernet ring network.
assistant-edge: Specifies the current switch as an assistant edge node on the
Ethernet ring network.
common-port comm-port: Specifies a common port.
edge-port edge-port: Specifies an edge port.
Description
Use the ring command to configure the node role for the current switch and the port
role for the port connecting to the Ethernet ring.
Use the undo ring command to remove the role configuration.
For an edge node or an assistant edge node, make sure you have removed the
secondary ring configuration before removing the primary ring configuration.
I. Node roles
z Master node: The node that initiates loop detection and prevents data loops. Each
ring has one and only one master node.
z Transit node: Nodes on a ring other than the master node are all transit nodes.
z Edge node: A node on the primary ring and a secondary ring at the same time is
an edge node. An edge node serves as a transit node on a primary ring and an
edge node on a secondary ring. In an RRPP domain, a secondary ring has two
edge nodes. You must specify one of them as an assistant edge node.
 Note:
In the same RRPP domain, different rings must have different Ring IDs.
II. Port roles
Of the two ports that connect the master node and a transit node to an Ethernet ring,
one is the primary port and the other the secondary port. The port roles are determined
by user configuration.
