Configuring control VLANs
Restrictions and guidelines
Perform this task on all nodes on an ERPS ring.
The control VLAN must be a VLAN that has not been created on the device.
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.
Do not enable 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 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.
