The Control VLAN must not be configured as a Layer 3 interface (with
an IP address), a dynamic VLAN (with GVRP enabled), nor as a private
VLAN. In addition, only ring ports may be added to the Control VLAN.
No other ports can be members of this VLAN. Also, the ring ports of the
Control VLAN must be tagged. Failure to observe these restrictions can
result in a loop in the network.
Once the ring has been activated with the enable command, the
configuration of the control VLAN cannot be modified. Use the no
enable command to stop the ERPS ring before making any
configuration changes to the control VLAN.

Before enabling a ring, the global ERPS function should be enabled with
the erps command, the east and west ring ports configured on each
node with the ring-port command, the RPL owner specified with the rpl
owner command, and the control VLAN configured with the control-vlan
command.
Once enabled, the RPL owner node and non-owner node state machines
will start, and the ring will enter idle state if no signal failures are
detected.
