Monitoring Licenses for the EX Series Switch
To enable and use some Junos OS features on the EX Series switch, you must purchase, install, and manage the appropriate software licenses. Each switch requires one license. For a Virtual Chassis deployment, two licenses are recommended for redundancy.
To monitor your installed licenses, perform the following tasks:
Displaying Installed Licenses and License Usage Details
