Configuring RRPP rings
When you configure an RRPP ring, you must make some configurations on the ports connecting each
node to the RRPP ring before configuring the nodes.
NOTE:
•
RRPP ports (connecting devices to an RRPP ring) must be Layer-2 Ethernet ports, Layer-2 GE ports,
Layer-2 XGE ports, or Layer-2 aggregate interfaces and cannot be member ports of any aggregation
group or smart link group.
• After configuring a Layer-2 aggregate interface as an RRPP port, you can still assign ports to or remove
ports from the aggregation group corresponding to the interface.
Configuring RRPP ports
CAUTION:
Do not enable OAM remote loopback function on an RRPP port. Otherwise, it might cause temporary
broadcast storms.
Perform this configuration on each node's ports intended for accessing RRPP rings.
To configure RRPP ports:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter interface view.
interface interface-type
interface-number
N/A
3. Configure the link type of the
interface as trunk.
port link-type trunk
Access by default.
For more information about the
command, see Layer 2—LAN
Switching Command Reference.
4. Assign the trunk port to the
protected VLANs of the RRPP
domain.
port trunk permit vlan { vlan-id-list
| all }
By default, a trunk port allows only
packets from VLAN 1 to pass
through.

command, see Layer 2—LAN
Switching Command Reference.
