Example 5: EPSR with management stacking

1.Configure stacking on the master node for the EPSR domain (host1)

The following commands must be entered into the CLI of this particular switch.

First, give the switch a host ID number so that the stack can identify it:

set system hostid=1 serialnumber=12345678

set system name=host1

Create the stacking VLAN and add the ring ports to it. Note the port numbering notation— these are ports 1 and 2 on stacking host 1. Because this VLAN will also be the EPSR control VLAN, this step also adds the ring ports to the control VLAN. Use the commands:

create vlan=stack vid=1000

add vlan=1000 port=1.0.1-1.0.2 frame=tagged

delete vlan=1 port=1.0.1-1.0.2

Add the stacking VLAN to the stack and enable stacking:

add stack interface=vlan1000

enable stack

2.Configure stacking on the first transit node (host2)

These commands must be entered into the CLI of this particular switch.

set system hostid=2 serialnumber=23456789 set system name=host2

create vlan=stack vid=1000

add vlan=1000 port=2.0.1-2.0.2 frame=tagged delete vlan=1 port=2.0.1-2.0.2

add stack interface=vlan1000 enable stack

3.Configure stacking on the second transit node (host3)

These commands must be entered into the CLI of this particular switch.

set system hostid=3 serialnumber=34567890 set system name=host3

create vlan=stack vid=1000

add vlan=1000 port=3.0.1-3.0.2 frame=tagged delete vlan=1 port=3.0.1-3.0.2

add stack interface=vlan1000 enable stack
