Syntax
control-vlan vlan-id
undo control-vlan
View
RRPP domain view
Default Level
2: System level
Parameters
vlan-id
: Control VLAN ID, in the range 2 to 4093.
Description
Use the
control-vlan
command to specify a control VLAN for an RRPP domain.
Use the
undo control-vlan
command to remove the control VLAN configured for an RRPP domain.
Note that:
z
The control VLAN must be a new one.
z
You need only configure a control VLAN for the primary ring. However, the control VLAN of a
subring is assigned automatically by the system and its VLAN ID is the control VLAN ID of the
primary ring plus 1. So, you should select two consecutive new VLANs. Otherwise, the
configuration fails.
z
Before configuring rings for an RRPP domain, make sure the RRPP domain is configured with a
control VLAN.
z
Before configuring RRPP rings for an RRPP domain, you can delete or modify the control VLAN
configured for the RRPP domain. However, after configuring RRPP rings for an RRPP domain, you
cannot delete or modify the control VLAN of the domain.
z
Deleting an RRPP domain deletes its control VLAN at the same time.
z
You cannot use the
undo vlan all
command to delete a control VLAN.
z
Do not enable QinQ or VLAN mapping on the control VLAN. Otherwise, RRPPDUs cannot be
forwarded properly.
