HP E4510-48G Command Reference Manual page 883

Parameters
ring-id: RRPP ring ID, in the range 1 to 64.
master: Specifies the device as the master node of the RRPP ring.
transit: Specifies the device as the transit node of the RRPP ring.
primary-port: Specifies the port as a primary port.
interface-type interface-number: Specifies a port by its type and number. The port can be a Layer-2 GE
port, Layer-2 XGE port, or Layer-2 aggregate port, and cannot be member ports of any aggregation
group, or smart link group.
secondary-port: Specifies the port as a secondary port.
level-value: RRPP ring level, with 0 representing primary ring and 1 representing subring.
edge: Specifies the device as the edge node of the RRPP ring.
assistant-edge: Specifies the device as the assistant edge node of the RRPP ring.
edge-port: Specifies the edge port for the node.
Description
Use the ring command to configure the node mode of the device, the role of the specified RRPP port,
and the level of the RRPP ring.
Use the undo ring command to remove the configuration.
Note that:
Before configuring rings for an RRPP domain, configure the control VLANs and protected VLANs
for the RRPP domain first.
The ID of an RRPP ring in a domain must be unique.
The maximum number of rings that can be configured on a device in all RRPP domains is 16.
If a device resides on multiple RRPP rings in an RRPP domain, only one primary ring exists within
these rings. The device plays a role of either edge node or assistant edge node on other subrings.
When an RRPP is enabled, you cannot configure its RRPP ports.
When configuring the edge node and the assistant-edge node, you must first configure the
primary ring, and then the subrings.
The node mode, RRPP port role, and ring level settings of an RRPP ring cannot be modified once
they are configured. To modify the settings, you must first remove the present settings.
You must remove all subring configurations before deleting the primary ring configuration of the
edge node or the assistant-edge node. However, an active RRPP ring cannot be deleted.
Related command: ring enable.
Examples
# Specify the device as the master node of primary ring 10 in RRPP domain 1, GigabitEthernet 1/0/1
as the primary port and GigabitEthernet 1/0/2 as the secondary port.
