How To Configure EPSR
If you leave all the ring ports in the default VLAN (vlan
1
), they will create a loop, unless
vlan
1
is part of the EPSR domain. To avoid loops, you need to do one of the following:
• make vlan
1
a data VLAN, or
• remove the ring ports from vlan
1
, or
• remove at least one of the ring ports from vlan
1
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
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-name
primaryport=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
This step enables the domain on each switch. Enter the command:
enable epsr=name
On each switch, configure the other ports and protocols that are required for your network.

iv. Configure the EPSR domain
v. Enable EPSR
3. Configure other ports and protocols as required
