Description: Provides managed objects for DHCPv6 server address assignment and prefix delegation on Juniper Networks E-series broadband 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-DHCPv6-MIB?

Juniper-DHCPv6-MIB is a Juniper Networks enterprise MIB for the E-series broadband access router family that provides statistics and status for the local DHCPv6 server component, covering address assignment and prefix delegation to subscribers. It exposes memory usage, active binding counts, and detailed per-message-type counters (solicits, advertises, requests renews, declines, releases, informs, confirms, rebinds, reconfigures). Its monitoring value spans both software resource health and service activity: juniDhcpv6LocalServerMemUsage indicates DHCPv6 server memory consumption (a software health indicator), while juniDhcpv6LocalServerNumBindings and the various Rx/Tx message counters reveal DHCPv6 service load and potential client-side problems such as spikes in declines or an absence of expected renews. It is a self-contained statistics MIB specific to Juniper's DHCPv6 implementation, without strong dependency on external standard MIBs. It is deployed on Juniper E-series edge routers acting as a DHCPv6 server for IPv6 broadband subscriber provisioning. Engineers can download the Juniper-DHCPv6-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in Juniper-DHCPv6-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.

Monitoring Examples

An operator would poll juniDhcpv6LocalServerMemUsage and juniDhcpv6LocalServerNumBindings to track DHCPv6 server memory pressure and the number of active subscriber address/prefix bindings, watching for memory growth or bindings dropping unexpectedly. juniDhcpv6LocalServerRxSolicits, juniDhcpv6LocalServerRxRenews, and juniDhcpv6LocalServerRxDeclines reveal client request patterns, where a surge in RxDeclines relative to RxSolicits could indicate address conflicts or a misconfigured pool. juniDhcpv6LocalServerTxAdvertises and juniDhcpv6LocalServerTxReconfigures show server responsiveness; a low advertise count despite high solicit volume would suggest the DHCPv6 server is failing to respond to client requests.

What Can Be Monitored

DHCPv6 server memory usage
active DHCPv6 bindings count
solicit/advertise message counters
renew/rebind message counters
decline/release message counters
reconfigure message counter

How to Use in IPNetwork Monitor

Example using juniDhcpv6LocalServerMemUsage OID:

Select a Juniper E-series broadband access router (local DHCPv6 server) 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 juniDhcpv6LocalServerMemUsage into the Find box to locate it in the OID tree, then select it and click OK. The amount (in bytes) of memory currently allocated to this local server. 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 sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.
