Description: Defines managed objects for the Juniper Networks local DHCPv6 server, supporting IPv6 prefix delegation and address assignment.

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-JDHCPV6-MIB?

JUNIPER-JDHCPV6-MIB is a Juniper Networks proprietary MIB module (part of the JUNOS DHCP MIB set) for managing the local DHCPv6 server function on Juniper routers, supporting IPv6 address assignment and prefix delegation. It belongs to Juniper's JUNOS enterprise MIB family focused on DHCP services. It exposes primarily performance/fault counters for the DHCPv6 server process: total and reason-coded dropped-packet counts (bad SAFD, bad send, short packet, bad message type, bad options, bad source address, relay hop count exceeded, no client ID) and message-type counters (DECLINE, SOLICIT, INFORMATION-REQUEST received), which together reveal the software health of the DHCPv6 service. Rising drop counters in specific categories point directly to malformed client/relay traffic or misconfiguration, making this a diagnostic MIB for DHCPv6 service reliability rather than hardware sensors. It conceptually depends on the DHCPv6 protocol standard (RFC 3315) for its message semantics, and is deployed on Juniper routers acting as local DHCPv6 servers in IPv6 access/edge networks. Engineers can download the JUNIPER-JDHCPV6-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in JUNIPER-JDHCPV6-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 Networks routers running JUNOS (DHCPv6 local server role)

Monitoring Examples

An administrator would poll jnxJdhcpv6LocalServerTotalDropped alongside the reason-specific counters like jnxJdhcpv6LocalServerBadOptionsDropped, jnxJdhcpv6LocalServerNoClientIdDropped, or jnxJdhcpv6LocalServerRelayHopCountDropped to pinpoint why DHCPv6 requests are being rejected. jnxJdhcpv6LocalServerSolicitReceived and jnxJdhcpv6LocalServerDeclineReceived would be tracked to gauge client request volume and address-conflict (DECLINE) rates. A sudden rise in jnxJdhcpv6LocalServerBadSrcAddressDropped, for example, would flag misconfigured relay agents or spoofed traffic hitting the DHCPv6 server.

What Can Be Monitored

total DHCPv6 packets dropped
drop reason breakdown (bad options, bad message type, no client ID, relay hop count exceeded)
DECLINE messages received

How to Use in IPNetwork Monitor

Example using jnxJdhcpv6LocalServerTotalDropped OID:

Select a Juniper Networks router running JUNO (local DHCPv6 server role) 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 jnxJdhcpv6LocalServerTotalDropped into the Find box to locate it in the OID tree, then select it and click OK. It reports the total DHCP v6 packets dropped. 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.
