Allied Telesis AT-9924T/4SP-A-20, AT-8948 Configure the master node switch A for the EPSR domain

Example 4: EPSR with Nested VLANs

1.Configure the master node (switch A) for the EPSR domain

Configure the EPSR control VLAN:

create vlan=vlan100 vid=100

add vlan=100 port=1-2 frame=tagged

Configure vlan50. This VLAN acts as both the nested VLAN and the EPSR data VLAN. The following commands create vlan50 and configure it as a nested VLAN:

create vlan=vlan50 vid=50 nested

add vlan=50 port=22 nestedtype=customer

add vlan=50 port=1-2 nestedtype=core

Remove the ring ports from the default VLAN:

delete vlan=1 port=1-2

Configure EPSR:

create epsr=example mode=master controlvlan=vlan100 primaryport=1 add epsr=example datavlan=vlan50

enable epsr=example

2.Configure the transit nodes (switches B, C and D) for the EPSR domain

Each of the transit nodes has the same EPSR configuration in this example.

Configure the EPSR control VLAN:

create vlan=vlan100 vid=100

add vlan=100 port=1-2 frame=tagged

Configure vlan50, which acts as both the nested VLAN and the EPSR data VLAN:

create vlan=vlan50 vid=50 nested

add vlan=50 port=22 nestedtype=customer

add vlan=50 port=1-2 nestedtype=core

Remove the ring ports from the default VLAN:

delete vlan=1 port=1-2

Configure EPSR:

create epsr=example mode=transit controlvlan=vlan100 add epsr=example datavlan=vlan50

enable epsr=example
