ERPS Configuration
C OMMAND U SAGE
◆ Configure one control VLAN for each ERPS ring. First create the VLAN to
be used as the control VLAN ( vlan , page 1114 ), add the ring ports for
the east and west interface as tagged members to this VLAN
( switchport allowed vlan , page 1117 ), and then use the control-vlan
command to add it to the ring.
◆ 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), 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.
◆ 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.
