Description: Juniper Networks MIB for monitoring Tunnel Load Balancing (TLB) statistics across tunnel endpoints on Juniper router platforms.

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-TLB-MIB?

JUNIPER-TLB-MIB is a Juniper Networks proprietary MIB that models the Tunnel Load Balancing (TLB) feature used on Juniper routing platforms (e.g., MX-series with load-balancing PICs) to distribute traffic across pools of real servers behind virtual services. It exposes configuration and status data organized around load-balancer instances, real servers, real-server groups, virtual services, and health-check profiles. It is explicitly useful for monitoring software/service health: it reports the network monitor's CPU usage (tlbNetmonCpuUsage) and monitor mode, alongside real-server reachability implied by the IP/port bindings, making it central to confirming that the load-balancing control plane and its member servers are functioning correctly. It builds on Juniper's general chassis/PIC identification model (e.g., correlating tlbMultiservicePIC/tlbMultiserviceInterface to physical interfaces) rather than a formal external standard. It is deployed on Juniper MX-series edge/core routers configured for in-line server load balancing or traffic steering, where JUNIPER-TLB-MIB SNMP monitoring confirms real-server health across the load-balancing pool.

IPNetwork Monitor allows you to monitor SNMP objects defined in JUNIPER-TLB-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 MX-series router with Multiservices/load-balancing PIC

Monitoring Examples

An administrator would poll tlbRealServerIpAddress and tlbRealServerGroupName across the real-server table to verify which backend servers are currently members of a given group, and cross-reference tlbVirtualServiceIpAddr/tlbVirtualServicePort to confirm the front-end virtual service mapping. Watching tlbNetmonCpuUsage over time reveals whether the health-monitoring process on the multiservices PIC (tlbMultiServicePIC) is becoming overloaded, which could delay detection of a failed real server. A sudden drop in reachable real servers under a given tlbProfileName signals a load-balancing pool degradation that needs investigation.

What Can Be Monitored

real server pool membership
virtual service IP/port mapping
load balancer profile assignment
network monitor CPU usage
monitor mode configuration
tunnel instance status

How to Use in IPNetwork Monitor

Example using jnxTLBRSClientPacketForwardCount OID:

Select a Juniper Networks MX-series router with Multiservices/load-balancing PIC (Tunnel Load Balancing) 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 jnxTLBRSClientPacketForwardCount into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. It reports the forward Packet Count. 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 Counter64-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.
