Description: Monitors and manages DHCP server and relay agent statistics and configuration on Ericsson routers.
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 ERICSSON-ROUTER-DHCP-MIB?
ERICSSON-ROUTER-DHCP-MIB is an Ericsson AB (Redback Networks heritage) proprietary MIB reporting DHCP server address-pool utilization for interfaces within a routing context. Its interface-threshold table, keyed by name/context, records pool size, available/in-use address counts, and falling/rising threshold values each with send-trap and log-message flags, while a range-threshold table extends the same detail per address range (start/end address). As a performance MIB it lets an administrator watch DHCP pool utilization and get alerted before a pool nears exhaustion on an Ericsson SmartEdge router. It is deployed on Ericsson (Redback Networks) SmartEdge/SM/SSR platforms. Engineers can download the ERICSSON-ROUTER-DHCP-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in ERICSSON-ROUTER-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
- Ericsson (Redback Networks) SmartEdge/SM/SSR platforms
Monitoring Examples
An administrator monitors eriRouterDhcpIntfThresholdInuse against eriRouterDhcpIntfThresholdRisingThreshold to catch a DHCP pool nearing exhaustion on an Ericsson SmartEdge router.
What Can Be Monitored
- DHCP address-pool utilization vs. configured thresholds

| eriRouterDhcpIntfThresholdTable | 1.3.6.1.4.1.193.218.2.30.1.1 | not-accessible | The purpose of this table is to allow monitoring of per interface DHCP server thresholds through SNMP. This table contains the objects which characterize DHCP server thresholds. Each row in the table corresponds to information about the leases in a DHCP server range for a particular interface and the corresponding capacity, usage and falling and rising thresholds. Objects defined in this table are only accessible within the context identified in the SNMP protocol (i.e. the community string in v1/v2c or the contextName in v3). | |

| U32 eriRouterDhcpIntfThresholdFallingThreshold | 1.3.6.1.4.1.193.218.2.30.1.1.1.6 | Unsigned32 | read-only | The falling threshold is a value which specifies that any enabled falling threshold events are to be generated when the value of the currently available leases drops to the falling threshold value via an allocation of a lease from the pool. The number of available leases is reported in eriRouterDhcpIntfThresholdAvailable. A falling threshold event is either a notification or a log message or both. Falling threshold events are enabled if either or both of eriRouterDhcpIntfThresholdFallingSendTrap and eriRouterDhcpIntfThresholdFallingLogMessage are true. Note, this is a falling threshold, so a falling threshold event will only be triggered on a transition of the value of eriRouterDhcpIntfThresholdAvailable dropping from (eriRouterDhcpIntfThresholdFallingThreshold+1) to eriRouterDhcpIntfThresholdFallingThreshold. |

| U32 eriRouterDhcpIntfThresholdRisingThreshold | 1.3.6.1.4.1.193.218.2.30.1.1.1.9 | Unsigned32 | read-only | The rising threshold is a value which specifies that any enabled rising threshold events are to be generated when the value of the currently available leases reaches the rising threshold value via a returning of a lease to the pool. The number of available leases is reported in eriRouterDhcpIntfThresholdAvailable. A rising threshold event is either a notification or a log message or both. Rising threshold events are enabled if either or both of eriRouterDhcpIntfThresholdRisingSendTrap and eriRouterDhcpIntfThresholdRisingLogMessage are true. Note, this is a rising threshold, so a rising threshold event will only be triggered on a transition of the value of eriRouterDhcpIntfThresholdAvailable increasing from (eriRouterDhcpIntfThresholdRisingThreshold-1) to eriRouterDhcpIntfThresholdRisingThreshold. |

When the sum of the all available DHCP leases in all interfaces of the context valid in the current view reaches the value of this object a falling threshold action of a trap, a log message, or both will be generated. This is a falling threshold, so the evaluation of whether to perform the action occurs upon allocation of a lease from the available pool of leases from any interface within the context. The action of whether to send a trap and/or log message is specified by the values of eriRouterDhcpCtxThresholdFallingSendTrap and eriRouterDhcpCtxThresholdFallingLogMessage. If there is no per context rising threshold, the value of this object will be zero and the values of eriRouterDhcpCtxThresholdFallingSendTrap and eriRouterDhcpCtxThresholdFallingLogMessage will be false. |

When the sum of the all available DHCP leases in all interfaces of the context valid in the current view reaches the value of this object a rising threshold action of a trap, a log message, or both will be generated. This is a rising threshold, so the evaluation of whether to perform the action occurs upon return of a lease to the available pool of leases defined in any interface within the context. The action of whether to send a trap and/or log message is specified by the values of eriRouterDhcpCtxThresholdRisingSendTrap and eriRouterDhcpCtxThresholdRisingLogMessage. If there is no per context rising threshold, the value of this object will be zero and the values of eriRouterDhcpCtxThresholdRisingSendTrap and eriRouterDhcpCtxThresholdRisingLogMessage will be false. |
