Set up a read-only SNMP community on Junos-based EX and QFX switches.
Connect via SSH or console and enter the Junos CLI's configuration mode.
Set a community string scoped to read-only authorization, and optionally restrict it to the collector's IP with a client list.

Junos applies SNMP config immediately after commit. Verify with a local show command before testing remotely.

Add the device using SNMP v2c and the community string you configured. Juniper devices generally respond well to bulk-walk polling, so default polling intervals work fine even on larger chassis.
