Someone did not log out of their session while editing the configuration on the switch

Entering configuration mode
Users currently editing the configuration:
root terminal d0 (pid 3112) on since 2023-04-05 02:18:53 CDT, idle 6w0d 05:47
{master:0}[edit]

To clear the session:

root@switch> show system users no-resolve

and then:

root@switch> request system logout user <item>

Where ‘<item>’ would be one of the following:

• all – all sessions owned by the named user
• pid – management session process ID
• terminal – terminal the user is logged into
• user – the name of the user

and you will be able to clear the session.
