Description: Juniper Networks MIB for managing SNMP agent parameters, community strings, and access control on Juniper E-series routers.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is Juniper-SNMP-MIB?

Juniper-SNMP-MIB manages SNMP-based management access itself on Juniper E-series routers, covering agent parameters such as maximum PDU size, community/access permissions, proxy status, and interface-specific SNMP data compression options. It exposes a compression settings table controlling compressed, enhanced, and restricted display modes per interface, alongside general SNMP access-control objects. Its monitoring value is meta-level software configuration status: confirming the SNMP agent itself is correctly sized and permissioned (juniSnmpMaxPduSize, juniSnmpAccessPermission) and that proxy forwarding (juniSnmpProxyStatus) is functioning, which matters when other MIB data appears incomplete or inaccessible. It is a self-contained enterprise MIB layered on top of standard SNMPv2 framework concepts (communities, access control) rather than IETF SNMP-FRAMEWORK-MIB directly. The Juniper SNMP MIB is used on Juniper E-series routers wherever SNMP management access needs vendor-specific tuning or interface-level compression.

IPNetwork Monitor allows you to monitor SNMP objects defined in Juniper-SNMP-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

  • Juniper E-series router

Monitoring Examples

An administrator checks juniSnmpMaxPduSize and juniSnmpAccessPermission to confirm the agent is configured to handle large polling requests and that the querying community has appropriate access. If SNMP responses are being truncated on a low-bandwidth link, juniSnmpIntfCompTable/juniSnmpIntfCompEntry settings (juniSnmpIntfCompCompressed, juniSnmpIntfCompEnhanced, juniSnmpIntfCompRestricted) reveal whether per-interface compression modes are enabled. juniSnmpProxyStatus is checked when SNMP requests are being proxied to another management context and appear to be failing or timing out.

What Can Be Monitored

  • SNMP max PDU size setting
  • SNMP access permission/community configuration
  • SNMP proxy status
  • per-interface SNMP compression mode
  • SNMP interface mode setting

How to Use in IPNetwork Monitor

Example using juniSnmpTrapGlobalDiscards OID:

Select a Juniper E-series router (SNMP management access configuration) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type juniSnmpTrapGlobalDiscards into the Find box to locate it in the OID tree, then select it and click OK. The number of trap requests that were discarded. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases between polls, since a rising count of errors, failures, or discards often points to a real underlying problem. Click Finish to create the monitor; you can adjust any parameter later.
