Description: Provides management objects for IP address pool allocation and utilization tracking on Juniper Networks E-series broadband access 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 Juniper-ADDRESS-POOL-MIB?

Juniper-ADDRESS-POOL-MIB is a Juniper Networks enterprise MIB for the E-series broadband access router family that manages and monitors IP address pools used for subscriber address assignment (e.g., via DHCP or PPP). It exposes configuration objects (pool name, start/end address, size) alongside operational utilization data (addresses in use, utilization percentage, and high/abated utilization thresholds). Its main monitoring value is software/service-level capacity status: administrators track address pool exhaustion risk by watching juniAddressPoolInUse and juniAddressPoolUtilPct against configured thresholds, catching pools nearing depletion before new subscribers fail to get an address. It is a self-contained address-pool management MIB with no strong dependency on other MIBs beyond standard SNMP conventions. It is deployed on Juniper E-series broadband edge routers serving large numbers of DHCP/PPP subscriber sessions. Engineers can download the Juniper-ADDRESS-POOL-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in Juniper-ADDRESS-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.

Monitoring Examples

An operator would poll juniAddressPoolTable/juniAddressPoolEntry to check juniAddressPoolInUse and juniAddressPoolUtilPct against juniAddressPoolSize for each juniAddressPoolName; a utilization percentage crossing juniAddressPoolHighUtilThreshold indicates the pool is nearing exhaustion and new subscriber sessions may soon be unable to obtain an address. juniAddressPoolAbatedUtilThreshold defines the lower bound at which a previously-triggered high-utilization alarm would clear. juniAddressPoolStart and juniAddressPoolEnd define the address range being tracked, and juniAddressPoolTraps would notify when thresholds are crossed.

What Can Be Monitored

address pool utilization percentage
addresses in use
pool size
high utilization threshold crossing
abated utilization threshold
pool name and address range

IP juniAddressPoolStart	1.3.6.1.4.1.4874.2.2.21.1.1.1.1.4	IpAddress	read-create	The starting IP address for the range of addresses comprising the 'first' pool profile entry. This object is deprecated in favor of juniAddressPoolProfileStart because it applies to a single address range and can only show one of possibly many address ranges found in the newer juniAddressPoolProfileTable. The value in this table maps to the value in the juniAddressPoolProfileTable for the entry with juniAddressPoolProfileIndex equal to 1.

A GET of this object returns the next available juniAddressPoolProfileIndex value to be used to create an entry in the associated juniAddressPoolProfileTable; or zero, if no valid juniAddressPoolProfileIndex is available. This object returns a value of zero when it is the lexicographic successor of a varbind presented in an SNMP GETNEXT or GETBULK request, for which circumstance it is assumed that a new index allocation is unintended.

juniAddressAliasTable	1.3.6.1.4.1.4874.2.2.21.1.1.4		not-accessible	A table of IP address alias entries. An alias is an alternate name for an existing local address pool within a virtual router. It is comprised of an alias name and a pool name. Multiple aliases may be configured for each virtual router. They will be stored in an alias table that will be managed by the virtual router's local address server. A maximum number of 32 aliases may be configured per virtual router. When an AAA Server requests an IP address from a specific local address pool within a virtual router, the local address server will first search its alias table for a matching alias name. If an alias exists, the IP address would be allocated from the pool specified by the alias. If no alias exists, the IP address would be allocated from the pool specified in the request. If a pool is not specified in the request, the local address server would disregard its alias table and allocate the first available IP address from its pools.
juniAddressAliasEntry	1.3.6.1.4.1.4874.2.2.21.1.1.4.1		not-accessible	An IP address alias entry.

Represents textual information taken from the NVT ASCII graphics character set (codes 32 through 126).
juniAddressSharedPoolTable	1.3.6.1.4.1.4874.2.2.21.1.1.5		not-accessible	A table of shared address pool configuration entries. These pools rely on DHCP for address allocations.

ROW juniAddressSharedPoolRowStatus	1.3.6.1.4.1.4874.2.2.21.1.1.5.1.2	RowStatus	read-create	Controls creation/deletion of address pools. Only value 'active' will be observed with GET. Only values 'createAndGo' and 'destroy' are supported for SET. To create an entry in this table, the following entry objects MUST be explicitly configured: juniAddressSharedPoolName, juniAddressSharedPoolDhcpPoolName. Once created, the objects in this table can not be modified.
OCT juniAddressSharedPoolName	1.3.6.1.4.1.4874.2.2.21.1.1.5.1.3	OCTET STRING	read-create	The name of this address pool. Represents textual information taken from the NVT ASCII graphics character set (codes 32 through 126). Values for this object are mutually exclusive with juniAddressPoolName.
