Creating and linking a probe

Use this task to create a probe and link it to devices.

When you link a probe to a network entity, traffic sent from or received by the entity is forwarded to the probe. You can then use host utitilies like tcpdump to monitor the traffic.

Enter the create probe command.
```
(vsh) create probe PB2
```
Enter the required create link command.
```
(vsh) create link -probe PB1 RT3 1/4
```

Example

(vsh) create probe PB2
vsh) create link -probe PB1 RT3 1/4
(vsh) show link
