Description: Defines managed objects for Session Manager IP pool allocation and utilization on Juniper Networks Mobile Gateway 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-MOBILE-GATEWAY-SM-IP-POOL-MIB?

JUNIPER-MOBILE-GATEWAY-SM-IP-POOL-MIB is a Juniper Networks, Inc. proprietary MIB reporting IP-address-pool utilization for Mobile-Edge Subscriber Management (mobile gateway) services. Its pool table, keyed by ID/logical-system/routing-instance, records name, type, free/in-use address counts and utilization percent, a range sub-table breaks the same down by address range, and a parallel SM-IP-pool table covers subscriber-management-specific pools. As a performance MIB it lets a mobile-core administrator watch IP-pool exhaustion risk for subscriber sessions on a Juniper mobile gateway. It is deployed on Juniper Networks mobile-gateway (packet-core) platforms. Engineers can download the JUNIPER-MOBILE-GATEWAY-SM-IP-POOL-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in JUNIPER-MOBILE-GATEWAY-SM-IP-POOL-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 mobile-gateway (packet-core) platforms

Monitoring Examples

A mobile-core administrator monitors jnxMbgIPPoolUtil to catch an IP address pool approaching exhaustion on a Juniper mobile gateway serving subscriber sessions.

How to Use in IPNetwork Monitor

Example using jnxMbgIPPoolFree OID:

Select a Juniper Networks mobile-gateway platform (subscriber IP pool utilization) 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 jnxMbgIPPoolFree 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 total number of free addresses in this pool. 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.
