Description: Juniper Networks MIB for managing tunneled subscriber session parameters in the Juniper E-series tunneled subscriber management framework.

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-TSM-MIB?

Juniper-TSM-MIB is a Juniper Networks enterprise MIB for the Tunnel Server Management (TSM) framework used on Juniper E-series routers to manage tunneled subscriber sessions such as L2TP or PPP tunnels terminating on dedicated tunnel server hardware. It exposes configuration and status data about tunnel server ports, including port location and type, hardware presence, and the number of available versus provisioned subscriber interfaces, plus an application registry mapping interface types to registered applications. It supports monitoring of hardware presence and interface capacity, letting operators verify tunnel server port cards are physically installed and that provisioned subscriber interface counts have not exceeded available capacity. As part of Juniper's E-series enterprise MIB family, it depends on Juniper's broader enterprise MIB structure and standard IF-MIB interface conventions for indexing. It is deployed in broadband/ISP access networks using Juniper E-series routers configured as tunnel servers for subscriber session termination. Network engineers evaluating or troubleshooting this functionality can download the Juniper-TSM-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in Juniper-TSM-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 E-series routers configured as tunnel servers

Monitoring Examples

An operator would poll juniTsmPortTable entries -- juniTsmPortHwPresent, juniTsmPortAvailableInterfaces, and juniTsmPortProvisionedInterfaces -- to confirm a tunnel server port card is physically present and check whether provisioned interfaces are approaching the available capacity, signaling the port is nearing subscriber capacity. The juniTsmAppRegistryTable (juniTsmAppRegistryIfType) can also be checked to confirm which application/interface types are registered on a given port.

What Can Be Monitored

tunnel server port hardware presence
available vs. provisioned subscriber interfaces per port
port location and type
registered application/interface types

How to Use in IPNetwork Monitor

Example using juniTsmApplicationActiveInterfaces OID:

Select a Juniper Networks E-series router configured as tunnel server (TSM) 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 juniTsmApplicationActiveInterfaces 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 number of application interfaces in use on the port. 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 Gauge32-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.

OIDs

OID symbolic	OID numeric	Type	Access	Description
juniTsmMIB	1.3.6.1.4.1.4874.2.2.72			The Tunnel Server Management (TSM) MIB for the Juniper Networks enterprise.

JUN juniTsmLocationType	1.3.6.1.4.1.4874.2.2.72.1.1.1	JuniTsmLocationType	read-only	Describes the interpretation of JuniTsmLocationValue object values into platform-dependent interface location components, e.g., 'slot.port'.
juniTsmPortTable	1.3.6.1.4.1.4874.2.2.72.1.1.2		not-accessible	This table allows dynamic server ports to be configured and also provides information about static ports available in the system. This table represents all ports known to the system. The presence of a port in this table does not guarantee that a card with this port is present in the chassis.
juniTsmPortEntry	1.3.6.1.4.1.4874.2.2.72.1.1.2.1		not-accessible	Configuration data.
JUN juniTsmPortLocation	1.3.6.1.4.1.4874.2.2.72.1.1.2.1.1	JuniTsmLocationValue	not-accessible	The value of a port location.
INT juniTsmPortType	1.3.6.1.4.1.4874.2.2.72.1.1.2.1.2	INTEGER	read-only	The port type: generalPurposeStatic - statically configured (always on) port, generalPurposeDynamic - dynamic port, which could be both configured with different maximum number of interfaces and unconfigured, securityStatic - static port equipped with encryption (IPSEC) hardware. securityDynamic - dynamic port with encryption (IPSEC) hardware, which could be both configured with different maximum number of interfaces and unconfigured.
T/F juniTsmPortHwPresent	1.3.6.1.4.1.4874.2.2.72.1.1.2.1.3	TruthValue	read-only	The port hardware is inserted.

If port is static this value cannot be changed. If the number of provisioned interfaces is decreased it may require a lengthy 'draining' process to bring number of allocated interfaces into compliance.

Applications allocate interfaces from a common pool, so this is not the only limit of application level interfaces. This value could be greater than juniTsmPortProvisionedInterfaces when the port is draining interfaces.
