SNMP enables you to monitor network devices from a central location. Many network management systems (NMS) are based on SNMP, and support for this protocol is a key feature of most network devices.


Juniper Networks provides many different platforms that support SNMP on Junos OS. Junos OS includes an onboard SNMP agent that provides remote management applications with access to detailed information about the devices on the network.


Junos OS supports:

  • version 1 (SNMPv1)
  • version 2 (SNMPv2c)
  • version 3 (SNMPv3)
