Description: Juniper Networks MIB for monitoring mobile forwarding plane statistics on Serving Gateway (SGW) within the mobile gateway architecture.
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-GW-SGW-MFWD-MIB?
JUNIPER-MOBILE-GW-SGW-MFWD-MIB is a Juniper Networks MIB for mobile-network gateway platforms, specifically monitoring the Mobile Packet Forwarding Daemon (MFWD) component of the Serving Gateway (SGW) function in a mobile core (LTE/EPC-style) architecture. It exposes objects identifying the service PIC handling forwarding, a configurable buffer memory limit, and a notification/trap framework for forwarding-plane events. Its monitoring focus is software/process and resource-status on specialized mobile-gateway line cards: administrators track buffer memory limit usage on the forwarding daemon and rely on notifications to learn about forwarding-plane faults or resource exhaustion affecting subscriber data-plane traffic. As a Juniper mobile-gateway component MIB, it depends on the broader Juniper Mobile Gateway MIB family and Juniper's service-PIC architecture conventions. It is deployed on Juniper MX-series routers configured as mobile Serving Gateways in carrier LTE/EPC mobile core networks. Engineers can download the JUNIPER-MOBILE-GW-SGW-MFWD-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in JUNIPER-MOBILE-GW-SGW-MFWD-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 MX-series router (mobile Serving Gateway)
Monitoring Examples
An operator would poll jnxMbgSgwMfwdServicePicName to identify which service PIC is running the SGW forwarding daemon, and jnxMbgSgwMfwdBufMemLimit to confirm the configured buffer memory ceiling for that daemon, watching for approach-to-limit conditions that could cause packet drops under high subscriber load. Notifications defined under jnxMbgSgwMfwdNotifications (using jnxMbgSgwMfwdNotificationVars) would alert operations staff to forwarding-plane faults on the SGW without requiring continuous polling.
What Can Be Monitored
- service PIC identity
- forwarding daemon buffer memory limit
- forwarding-plane fault notifications
