Configuration Procedure; Configuring Protected Vlans - H3C S5120-EI Series Configuration Manual

Configuration procedure

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 configuring RRPP rings in an RRPP domain, configure the same protected VLANs for all nodes in
the RRPP domain first. All VLANs that the RRPP ports are assigned to should be protected by the RRPP
domains.
You can configure protected VLANs through referencing Multiple Spanning Tree Instances (MSTIs).
Before configuring protected VLANs, configure the mappings between MSTIs and the VLANs to be
protected. (A device working in PVST mode automatically maps VLANs to MSTIs.) For more information
about MSTIs and PVST, see Layer 2—LAN Switching Configuration Guide.
Perform this configuration on all nodes in the RRPP domain to be configured.
To configure protected VLANs:
Step
1. Enter system view.
2. Enter MST region view.
3. Configure the
VLAN-to-instance mapping
table.
4. Activate MST region
configuration manually.

Remarks
N/A
Not required if the device is
operating in PVST mode.
For more information about the
command, see Layer 2—LAN
Switching Command Reference.
Optional.
Use either approach.
All VLANs in an MST region are
mapped to MSTI 0 (the CIST) by
default.
Not required if the device is
operating in PVST mode.
