Configuring Rrpp Nodes - HP A5120 EI Configuration Manual

To do...
Assign the trunk port to the
protected VLANs of the RRPP
domain
Disable STP
Configure the port to trust the
802.1p precedence of the
received packets
NOTE:

RRPP ports always allow packets of the control VLANs to pass through.

For more information about the port link-type trunk and port trunk permit vlan commands, see the
LAN Switching Command Reference

For more information about the undo stp enable command, see the
Reference
.

The 802.1p priority of trusted packets on the RRPP ports must be configured, so that RRPP packets take higher
precedence than data packets when passing through the RRPP ports. For more information about the qos trust
dot1p command, see the

Do not enable OAM remote loopback function on an RRPP port. Otherwise, it may cause a temporary broadcast
storm.

Do not configure physical-link-state change suppression time on a port accessing an RRPP ring to accelerate
topology convergence. For more information, see the undo link-delay command (

Configuring RRPP nodes

NOTE:

The maximum number of rings that can be configured on a device in all RRPP domains is 16.

If a device carries multiple RRPP rings in an RRPP domain, only one ring can be configured as the primary ring
on the device, and the role of the device on a subring can only be an edge node or an assistant-edge node.
Specifying a master node
Perform this configuration on a device to be configured as a master node.
Follow these steps to specify a master node:
To do...
Enter system view
Enter RRPP domain view
Specify the current device as the
master node of the ring, and
specify the primary port and the
secondary port
Use the command...
port trunk permit vlan { vlan-id-list
| all }
undo stp enable
qos trust dot1p
