protected-vlan

Use protected-vlan to configure the protected VLANs for the RRPP domain.
Use undo protected-vlan to remove the protected VLAN configuration of the RRPP domain.
Syntax
protected-vlan reference-instance instance-id-list
undo protected-vlan [ reference-instance instance-id-list ]
Default
No protected VLAN is specified for an RRPP domain.
Views

Default command level
2: System level
Parameters
reference-instance instance-id-list: Specifies the Multiple Spanning Tree Instances (MSTIs) you want to
reference in the form of instance-id-list = { instance-id [ to instance-id ] }&<1- 1 0>, where instance-id is an
MSTI ID that ranges from 0 to 128. instance-id 0 represents the common internal spanning tree (CIST).
&<1- 1 0> means that you can specify up to 10 MSTI IDs or ID ranges. You can use the display stp
region-configuration command to display the instance-to-VLAN mappings. (A device operating in PVST
mode automatically maps VLANs to MSTIs.)
Usage guidelines
To be compatible with old-version RRPP, which does not support protected VLAN configuration, an RRPP
domain protects all VLANs on a device started with an old-version configuration file.
If the reference-instance instance-id-list option is specified, the undo protected-vlan command removes
configuration of VLANs mapped to the specified MSTIs. Otherwise, the command removes configuration
of all protected VLANs.
You can delete or modify the protected VLANs configured for an RRPP domain before and after you
configure rings for it. However, you cannot delete configuration of all protected VLANs configured for the
domain.
When the VLAN-to-MSTI mappings change, the protected VLANs of an RRPP domain also changes
according to the MSTIs configured for the domain.
Examples
# Map VLANs 1 through 30 to MSTI 1, activate the MST region configuration, configure VLAN 100 as
the control VLAN of RRPP domain 1, and configure VLANs mapped to MSTI 1 as the protected VLANs
of RRPP domain 1.
