Configuring control VLANs
Follow these guidelines when you configure control VLANs:
Configure the same control VLAN for all nodes in an ERPS instance.
Do not configure the default VLAN of an ERPS ring member port as the control VLAN, and do not enable QinQ or VLAN mapping on control VLANs. If you do, ERPS packets cannot be correctly forwarded and received.
Make sure the ERPS instance has been configured. After the ERPS instance is enabled, the control VLAN cannot be changed.
For a device that connects two rings to forward Flush packets correctly, make sure only the ports that connect to the ERPS rings are configured with the control VLAN.
For a device not configured with ERPS to transparently transmit ERPS packets, make sure only the two ports accessing the ERPS ring permit packets from the control VLAN. If other ports on the device permit packets from the control VLAN, the packets from other VLANs might enter the control VLAN and strike the ERPS ring.
To configure a control VLAN:
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter ERPS ring view. | erps ring ring-id | N/A |
3. Enable ERPS instance view. | instance instance-id | N/A |
4. Configure a control VLAN. | control-vlan vlan-id | By default, an ERPS instance does not have control VLANs. |
