Configuring Protected Vlans - HP 5130 EI Series Configuration Manual

secondary control VLAN ID. For the control VLAN configuration to succeed, make sure the IDs of the two
control VLANs are consecutive and have not been previously assigned.
Follow these guidelines when you configure control VLANs:
Do not configure the default VLAN of a port accessing an RRPP ring as the control VLAN, and do
•
not enable QinQ or VLAN mapping on control VLANs. If you do, RRPPDUs cannot be correctly
forwarded.
• After you configure RRPP rings for an RRPP domain, you cannot delete or modify the primary control
VLAN of the domain. You can only use the undo control-vlan command to delete a primary control
VLAN.
To transparently transmit RRPPDUs on a device not configured with RRPP, make sure only the two
•
ports accessing the RRPP ring permit packets from the control VLANs. Otherwise, the packets from
other VLANs might enter the control VLANs in transparent transmission mode and strike the RRPP
ring.
Perform this task on all nodes in the RRPP domain to be configured.
To configure control VLANs:
Step
1. Enter system view.
2. Enter RRPP domain view.
3. Configure the primary control
VLAN for the RRPP domain.

Configuring protected VLANs

Before you configure RRPP rings in an RRPP domain, configure the same protected VLANs for all nodes
in the RRPP domain. All VLANs to which the RRPP ports are assigned must be protected by the RRPP
domains.
Protected VLANs are configured by referencing Multiple Spanning Tree Instances (MSTIs). The protected
VLAN configuration method varies by the spanning tree mode:
In STP, RSTP, or MSTP mode, you must manually configure the mappings between VLANs and
•
MSTIs.
In PVST mode, the device automatically maps each VLAN to an MSTI. When the spanning tree
•
protocol is disabled globally, all VLANs are automatically mapped to MSTI 0.
For more information about spanning tree, see Layer 2—LAN Switching Configuration Guide.
IMPORTANT:
When you configure load balancing, you must configure different protected VLANs for different RRPP
domains.
Perform this task on all nodes in the RRPP domain to be configured.
To configure protected VLANs:
Command
system-view
rrpp domain domain-id
control-vlan vlan-id
