Configure SNMP on a Juniper (Junos) switch

Set up a read-only SNMP community on Junos-based EX and QFX switches.

What you'll need

  • Admin access to the device's CLI (console, SSH or Telnet)
  • Configuration-mode access
  • A Zynty account with Editor or Admin role
1

Enter configuration mode

Connect via SSH or console and enter the Junos CLI's configuration mode.

Configure a read-only community

Set a community string scoped to read-only authorization, and optionally restrict it to the collector's IP with a client list.

configure
set snmp community zyntyRO authorization read-only
set snmp community zyntyRO client-list-name ZYNTY-COLLECTOR
set snmp client-list ZYNTY-COLLECTOR 10.20.0.50/32
set snmp location "DC - Frankfurt"
set snmp contact netops@company.com
commit

Confirm the community is active

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

show snmp mib walk system

Add the switch in Zynty

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.
