HP A5120 EI - Configuring RRPP Nodes

65
To do…
Use the command…
Remarks
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 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 ( 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.
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…
Use the command…

master node of the ring, and

secondary port
