JUNIPER-SUBSCRIBER-MIB

Description: Juniper Networks MIB for monitoring active subscriber session counts, states, and per-subscriber statistics 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.

JUNIPER-SUBSCRIBER-MIB is a Juniper Networks enterprise MIB for monitoring broadband subscriber sessions on Juniper E-series edge routers, tracking how many subscribers are connected and their per-subscriber accounting/interface details. It exposes aggregate subscriber counts (total and active), per-subscriber session tables, per-port subscriber counts, a hardware-index mapping table linking subscribers to physical interface hardware, and an accounting table for usage statistics. Its monitoring purpose is primarily software/session-state health: confirming the active subscriber count matches expectations, catching a sudden mass drop in sessions (which would indicate a card or line failure), and correlating subscribers to the physical interface hardware they're terminated on. It is Juniper-specific but conceptually parallels standard interface (IF-MIB) indexing for tying logical subscribers to physical hardware. It is deployed on Juniper E-series broadband edge routers used by ISPs for subscriber management (e.g. PPPoE/DHCP subscriber termination). Engineers can download the JUNIPER-SUBSCRIBER-MIB file directly to load it into their MIB browser.

An administrator polls jnxSubscriberTotalCount and jnxSubscriberActiveCount to track overall subscriber session health, alerting if jnxSubscriberActiveCount drops sharply, which would indicate a line card failure or upstream authentication outage. jnxSubscriberTable (jnxSubscriberEntry) is walked per subscriber, cross-referenced with jnxSubscriberInterfaceHardwareIndexTable (using jnxSubscriberInterfaceHardwareIndexHandleHiWord/LoWord) to identify exactly which physical port hardware a subscriber is terminated on. jnxSubscriberAccountingTable and jnxSubscriberPortCountTable are used to verify per-port subscriber density stays within provisioned limits.
