Command Syntax

Parameters

Parameter	Description
ring <ring-id>	Specifies the ID of the ring. The value is an integer that ranges from 1 to 8.
instance <instance-id>	Specifies the instance ID for a ring. The value is an integer that ranges from 1 to 2.
protected-instance <msti>	Specifies the MSTP instance of VLANs that are protected by this ring instance. The value is an integer that ranges from 1 to 16.

Usage Guidelines

protected-instance <msti> is the MSTP instance that are protected by the ring instance, so MSTP instance and VLAN mapping needs to be configured before configure ERPS by using command: set protocols spanning-tree mstp msti <msti> vlan <vlan-id>.

Make sure that the control VLAN and data VLANs of the ERPS ring have all been mapped to the MSTP instance.

The traffic of MSTP instance 0 is blocked by ERPS ring.

Multiple protected-instance (protected MSTP instance) can be added to one ERPS instance.

Example

Configure the MSTP instance that is protected by this ring instance.
