Implementing Unidirectional and Bidirectional Virtual Wire Links
In this section you configure a single bidirectional Virtual Wire link using the port-association-create command with the option virtual-wire to create a single bidirectional Virtual Wire link. This can be implemented in two ways that are functionally equivalent:
Configuring Virtual Wire direction individually - or
Configuring a Virtual Wire link using the bidir parameter
1. To configure a unidirectional Virtual Wire link from device A to device B, enter the following command:
CLI network-admin@Leaf1 > port-association-create name A-to-B virtual-wire master-ports 10 slave-ports 20
REST API - POST http://<switch-ip>/vRest/port-associations
{
“name”: “A-to-B”,
“virtual-wire”:”true”,
“master-ports”: “10”,
“slave-ports”: “20”
}
* 
Informational Note: Please note that the parameter “mode(?) must be set to “true”. This is the case when the switch is running in Virtual Wire mode and you are configuring Virtual Wire features.
1. To configure a unidirectional Virtual Wire link from device B to device A, enter the following command:
REST API - POST http://<switch-ip>/vRest/port-associations
{
“name”: “B-to-A”,
“virtual-wire”:”true”,
“master-ports”: “20”,
“slave-ports”: “10”
}
1. To configure a bidirectional Virtual Wire link from device A to device B, enter the following command:
CLI network-admin@Leaf1 > port-association-create name A-to-B bidir virtual-wire master-ports 10 slave-ports 20
REST API - POST http://<switch-ip>/vRest/port-associations
{
“name”: “A-to-B”,
“bidir”,
“virtual-wire”:”true”,
“master-ports”: “20”,
“slave-ports”: “10”
}
To display existing Virtual Wire links, use the port-association-show command:
CLI network-admin@Leaf1 > port-association-show
switch          name        master-ports  slave-ports  policy       virtual-wire bidir
---------       ------      -----------   -----------  -----------  ------------ -----
vw-switch       A-to-B      10            20           all-masters  true         true
 
REST API - GET http://<switch-ip>/vRest/port-associations
To delete an existing Virtual Wire link, use the port-association-delete command with the name string parameter:
CLI network-admin@Leaf1 > port-association-delete name A-to-B
REST API - DELETE http://<switch-ip>/vRest/port-associations/A-to-B
