ADD EPSR=epsr-name DATAvlan={vlan-name|1..4094}

This command adds a data VLAN to the selected EPSR instance, in order to 
provide protection against network loops in that VLAN.

The following configuration rules apply when adding an EPSR data VLAN:

■

The maximum number of data VLANs that can be added to an EPSR 
instance is 512.

■

The VLAN must not already be in the EPSR instance as either a control 
VLAN or data VLAN.

■

A VLAN cannot be added to an EPSR instance if it is already a control 
VLAN for another EPSR instance.

■

A VLAN cannot be added to an EPSR instance if it is already a data VLAN 
for another instance, and that instance has a ring port that is also in this 
instance.

■

The VLAN need not contain the ring ports in order to be added to an EPSR 
instance. Also, adding the VLAN to the EPSR instance before adding the 
ports to the data VLAN reduces the possibility of creating loops while 
configuring the ring.

To add the vlan2 VLAN to the EPSR instance called blue use the command:

add epsr=blue vlan=vlan2

delete epsr datavlan
show epsr
