How To Configure EPSR
This section first outlines, step-by-step, how to configure EPSR. Then it discusses changing
the settings for the control VLAN, if you need to do this after initial configuration.
Configuring EPSR
EPSR does not in itself limit the number of nodes that can exist on any given ring. Each switch
can participate in up to
1
6 rings.
If you already have a ring in a live network, disconnect the cable between any two of the
nodes before you start configuring EPSR, to prevent a loop.
On each switch, perform the following configuration steps. Configuration of the master node
and each transit node is very similar.
This step creates the control VLAN and adds the ring ports to it as tagged ports.
Enter the commands:
create vlan=control-vlan-name vid=control-vid
add vlan=control-vid port=ring-ports frame=tagged
Note that you can use trunk groups for the ring ports.
This step creates the data VLAN (or VLANs—you can have as many as you want) and
adds the ring ports as tagged ports.
Enter the commands:
create vlan=data-vlan-name vid=data-vid
add vlan=data-vid port=ring-ports frame=tagged
The two ring ports must belong to the control VLAN and all data VLANs.
1. Connect your switches into a ring
2. On each switch, configure EPSR
i. Configure the control VLAN
ii. Configure the data VLAN
