Configuring Rrpp Rings; Configuring Rrpp Ports - 3Com 4500G Family Configuration Manual

Configuring RRPP Rings

When configuring an RRPP ring, you must make some configurations on the ports connecting each
node to the RRPP ring before configuring the nodes.
RRPP ports, that is, ports connecting devices to an RRPP ring, must be Layer-2 GE ports, Layer-2
XGE ports, or Layer-2 aggregate interfaces and cannot be member ports of any aggregation group,
service loopback 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

Perform this configuration on each node's ports intended for accessing RRPP rings.
Follow these steps to configure RRPP ports:
To do...
Enter system view
Enter interface view
Configure the link type of the
interface as trunk
Configure the trunk port carries
the protected VLAN(s)
Disable STP
Configure the port to trust the
802.1p precedence of the
received packets
Use the command...
system-view
interface interface-type
interface-number
port link-type trunk
port trunk permit vlan
{ vlan-id-list | all }
undo stp enable
qos trust dot1p
