To configure the vSRX Virtual Firewall instance using the CLI:

Verify that the instance is powered on.
Log in using the username and password credentials for your vSRX Virtual Firewall VM deployment.
Start the CLI.
```
root#cli
root@>
```
Enter configuration mode.
```
configure 
[edit]
root@#
```
Set the root authentication password by entering a cleartext password, an encrypted password, or an SSH public key string (DSA or RSA).
```
[edit]
root@# set system root-authentication plain-text-password
New password: password 
Retype new password: password 
```
Configure the traffic interfaces.
```
[edit]
root@# set interfaces ge-0/0/0 unit 0 family inet address assigned_ip/netmask
root@# set interfaces ge-0/0/1 unit 0 family inet address assigned_ip/netmask
```
Note:
Configuration of the management interface fxp0 for the vSRX Virtual Firewall is not necessary, because it is configured during vSRX Virtual Firewall VM deployment. Do not change the configuration for interface fxp0 and the default routing table or you will lose connectivity.

Configure routing interfaces to isolate management network and traffic network.

Optionally, use the show command to display the configuration to verify that it is correct.

Note:

Certain Junos OS software features require a license to activate the feature. To enable a licensed feature, you need to purchase, install, manage, and verify a license key that corresponds to each licensed feature. To conform to software feature licensing requirements, you must purchase one license per feature per instance. The presence of the appropriate software unlocking key on your virtual instance allows you to configure and use the licensed feature.

See Managing Licenses for vSRX for details.
