Configuring Rrpp Nodes - 3Com 4500G Family Configuration Manual

For detailed information about the port link-type trunk command and port trunk permit vlan
{ vlan-id-list | all } command, refer to VLAN Commands in the Access Volume.
For detailed information about the undo stp enable command, refer to MSTP Commands in the
Access Volume.
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.
Do not enable OAM remote loopback function on an RRPP port. Otherwise, this may cause
temporary broadcast storm.
You are recommended not to configure physical-link-state change suppression time on a port
accessing an RRPP ring to accelerate topology convergence. For details, refer to Ethernet Port
Configuration in the Access Volume.

Configuring RRPP Nodes

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
Specifying a transit node
Perform this configuration on a device to be configured as a transit node.
Follow these steps to specify a transit node:
Use the command...
system-view
rrpp domain domain-id
ring ring-id node-mode master
[ primary-port interface-type
interface-number ] [ secondary-port
interface-type interface-number ] level
level-value
1-13
