Using a dscp session

Before you can view, add, or modify server entries, you must open a session so that you can interact with the interfaces file.

You can have multiple sessions open at one time.

To open a session with the interfaces file

Enter:
```
open InterfacesDriver
```
When you open a session, dscp provides the session’s number. For example, if you open a session using the open InterfacesDriver command, dscp displays the following message:
```
ok
```
```
Session 1 InterfacesDriver>>
```

To list all open sessions

Enter:
```
sess
```

To switch to another open session

Enter the following, where sess is the session number:
```
switch sess
```
For example, you are switched to session 3 if you enter:
```
switch 3
```
The switch keyword is optional. For example, entering “3” also switches you to session 3.

To close a session

Enter the following, where sess is the session number:
```
close sess
```
For example, session 3 closes if you enter:
```
close 3
```
If you do not specify a session number, dscp closes the current session.
