Command Usage
◆ The Control VID must be included in one of inclusion VLAN groups.
◆ Configure one control VLAN for each ERPS instance. First create the VLAN to be
used as the control VLAN (vlan, page 587), add the VLAN to an ERPS VLAN
group (erps vlan-group), add the ring ports for the east and west interface as
tagged members to this VLAN (switchport allowed vlan, page 590), and then
use the control-vlan command to add it to the ERPS instance.
◆ The following restrictions are recommended to avoid creating a loop in the
network or other problems which may occur under some situations:
■
The Control VLAN must not be configured as a Layer 3 interface (with an IP
address), nor as a dynamic VLAN (with GVRP enabled).
■
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.
◆ Once the instance has been activated with the enable (instance) command, the
configuration of the control VLAN cannot be modified. Use the no enable (ring)
command to stop the ERPS instance before making any configuration changes
to the control VLAN.
