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-DHCP-MIB?
JUNIPER-MOBILE-GATEWAY-DHCP-MIB is a vendor-specific MIB from Juniper Networks, Inc. that defines objects for Mobile-Edge DHCP services on its Mobile Gateway platform, registered under jnxMobileGatewayMibRoot as jnxMbgDhcpMib. Rather than exposing a polled table of counters, this compact module is built around notification variables (jnxMbgDhcpServerIP, jnxMbgDhcpLogicalSystemName, jnxMbgDhcpRoutingInstanceName, jnxMbgDhcpProfileName, jnxMbgDhcpPoolName, jnxMbgDhcpReachability) that accompany two NOTIFICATION-TYPE traps: jnxMbgDhcpServerReachability and jnxMbgDhcpAddrPoolExhaust. This lets an NMS receive asynchronous alerts when a configured DHCP server becomes unreachable or when an address pool within a DHCP profile runs out of addresses to assign to mobile subscribers, which is critical for mobile-edge/GGSN-style gateway deployments that lease IP addresses per logical system and routing instance. It depends on JUNIPER-SMI for its enterprise OID root and INET-ADDRESS-MIB/SNMPv2-SMI for common types, and administrators can download the JUNIPER-MOBILE-GATEWAY-DHCP-MIB file to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in JUNIPER-MOBILE-GATEWAY-DHCP-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 (mobile-edge DHCP services)
Monitoring Examples
An operator subscribes to jnxMbgDhcpAddrPoolExhaust traps, which carry jnxMbgDhcpPoolName and jnxMbgDhcpProfileName; receiving this trap indicates a specific DHCP address pool has been exhausted and new mobile subscribers in that profile cannot obtain an IP address.
What Can Be Monitored
- DHCP server reachability (jnxMbgDhcpReachability, jnxMbgDhcpServerReachability trap)
- address pool exhaustion events (jnxMbgDhcpAddrPoolExhaust trap)
- DHCP server identity per notification (jnxMbgDhcpServerIP)
- logical-system and routing-instance context of DHCP events (jnxMbgDhcpLogicalSystemName, jnxMbgDhcpRoutingInstanceName)
- DHCP profile and pool identification (jnxMbgDhcpProfileName, jnxMbgDhcpPoolName)
