Configuring RRPP ports
Perform this configuration on each node’s ports intended for accessing RRPP rings.
Follow these steps to configure RRPP ports:

Configure the link type of the port
as trunk
port link-type trunk
Required
By default, the link type of a port is
access.
Assign the trunk port to the
protected VLANs of the RRPP
domain
port trunk permit vlan
{
vlan-id-list
|
all
}
Required
By default, a trunk port allows only
packets of VLAN 1 to pass through
Disable STP
undo stp enable
Required
Enabled by default
Configure the port to trust the
802.1p precedence of the
received packets
qos trust
dot1p
Required
By default, the port priority is
trusted.
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
Layer 2—LAN Switching Command Reference.
•
For more information about the
undo stp enable
command, see the
Layer 2—LAN Switching Command
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
ACL and QoS Command Reference.
•
Do not enable OAM remote loopback function on an RRPP port. Otherwise, it may cause 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
(Layer
2—LAN Switching Command Reference).
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.
