How To Configure EPSR

iii. Remove the ring ports from the default VLAN

If you leave all the ring ports in the default VLAN (vlan1), they will create a loop, unless vlan1 is part of the EPSR domain. To avoid loops, you need to do one of the following:

•

•

make vlan1 a data VLAN, or

remove the ring ports from vlan1, or

•remove at least one of the ring ports from vlan1 on at least one of the switches. We do not recommend this option, because the action you have taken is less obvious when maintaining the network later.

In this How To Note, we remove the ring ports from the default VLAN. Use the command:

delete vlan=1 port=ring-ports

iv. Configure the EPSR domain

This step creates the domain, specifying whether the switch is the master node or a transit node. It also specifies which VLAN is the control VLAN, and on the master node which port is the primary port.

Enter one of the following commands:

On the master node:

create epsr=name mode=master controlvlan=control-vlan-nameprimaryport=port-number

On each transit node:

create epsr=name mode=transit controlvlan=control-vlan-name

This step also adds the data VLAN to the domain. Enter the command:

add epsr=name datavlan=data-vlan-name

v. Enable EPSR

This step enables the domain on each switch. Enter the command:

enable epsr=name

3.Configure other ports and protocols as required

On each switch, configure the other ports and protocols that are required for your network.
