Description: Defines objects for configuring proxy forwarding of SNMP messages between different management domains.

IPNetwork Monitor uses several OIDs from this MIB in network discovery and polling the applicable devices. Start monitoring SNMP-PROXY-MIB with a free 30-day trial of IPNetwork Monitor.

What Is SNMP-PROXY-MIB?

SNMP-PROXY-MIB, defined in RFC 3413, is a vendor-neutral IETF standard MIB module providing objects for remotely configuring an SNMP proxy-forwarding application that relays SNMP messages between different management domains or contexts. It exposes configuration data — proxy entries specifying source/target contexts, engine IDs, and forwarding parameters — rather than performance counters or hardware status. Its monitoring relevance centers on the management infrastructure itself: confirming that proxy forwarding rules are correctly provisioned and active (via row status) so management traffic reaches the right target, rather than reporting on CPU, memory, or environmental sensors. It depends on and is designed to work with the broader SNMP Management Architecture (RFC 3411-3418), particularly SNMP-TARGET-MIB for the target parameters referenced by its proxy entries. It is typically deployed on SNMP mid-level managers or gateway agents that need to bridge management traffic across security or administrative domain boundaries. Engineers implementing or auditing this functionality typically reference the SNMP-PROXY-MIB RFC/standard documentation for the authoritative specification.

IPNetwork Monitor allows you to monitor SNMP objects defined in SNMP-PROXY-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

vendor-neutral, standards-based MIB, not tied to a specific manufacturer
SNMP proxy/gateway agents and mid-level managers

Monitoring Examples

An admin would walk snmpProxyTable/snmpProxyEntry, examining snmpProxyType, snmpProxyContextEngineID, and snmpProxyContextName to confirm which proxy relationships are configured, and check snmpProxyRowStatus to verify a given proxy entry is active rather than notReady or notInService. If snmpProxySingleTargetOut or snmpProxyMultipleTargetOut references a snmpProxyTargetParamsIn value that no longer matches a valid target, forwarded requests would silently fail, which the row status and target references help diagnose.

What Can Be Monitored

proxy forwarding entry configuration
proxy type (read/write/trap/inform)
target context engine ID and name
row status of proxy entries
target parameters used for forwarding

OIDs

OID symbolic	OID numeric	Type	Access	Description
snmpProxyMIB	1.3.6.1.6.3.14			This MIB module defines MIB objects which provide mechanisms to remotely configure the parameters used by a proxy forwarding application. Copyright (C) The Internet Society (2002). This version of this MIB module is part of RFC 3413; see the RFC itself for full legal notices.
snmpProxyObjects	1.3.6.1.6.3.14.1
snmpProxyTable	1.3.6.1.6.3.14.1.2		not-accessible	The table of translation parameters used by proxy forwarder applications for forwarding SNMP messages.
snmpProxyEntry	1.3.6.1.6.3.14.1.2.1		not-accessible	A set of translation parameters used by a proxy forwarder application for forwarding SNMP messages. Entries in the snmpProxyTable are created and deleted using the snmpProxyRowStatus object.
STR snmpProxyName	1.3.6.1.6.3.14.1.2.1.1	SnmpAdminString	not-accessible	The locally arbitrary, but unique identifier associated with this snmpProxyEntry.
INT snmpProxyType	1.3.6.1.6.3.14.1.2.1.2	INTEGER	read-create	The type of message that may be forwarded using the translation parameters defined by this entry.
SNM snmpProxyContextEngineID	1.3.6.1.6.3.14.1.2.1.3	SnmpEngineID	read-create	The contextEngineID contained in messages that may be forwarded using the translation parameters defined by this entry.
STR snmpProxyContextName	1.3.6.1.6.3.14.1.2.1.4	SnmpAdminString	read-create	The contextName contained in messages that may be forwarded using the translation parameters defined by this entry. This object is optional, and if not supported, the contextName contained in a message is ignored when selecting an entry in the snmpProxyTable.
STR snmpProxyTargetParamsIn	1.3.6.1.6.3.14.1.2.1.5	SnmpAdminString	read-create	This object selects an entry in the snmpTargetParamsTable. The selected entry is used to determine which row of the snmpProxyTable to use for forwarding received messages.
STR snmpProxySingleTargetOut	1.3.6.1.6.3.14.1.2.1.6	SnmpAdminString	read-create	This object selects a management target defined in the snmpTargetAddrTable (in the SNMP-TARGET-MIB). The selected target is defined by an entry in the snmpTargetAddrTable whose index value (snmpTargetAddrName) is equal to this object. This object is only used when selection of a single target is required (i.e. when forwarding an incoming read or write request).
SNM snmpProxyMultipleTargetOut	1.3.6.1.6.3.14.1.2.1.7	SnmpTagValue	read-create	This object selects a set of management targets defined in the snmpTargetAddrTable (in the SNMP-TARGET-MIB). This object is only used when selection of multiple targets is required (i.e. when forwarding an incoming notification).
STO snmpProxyStorageType	1.3.6.1.6.3.14.1.2.1.8	StorageType	read-create	The storage type of this conceptual row. Conceptual rows having the value 'permanent' need not allow write-access to any columnar objects in the row.
ROW snmpProxyRowStatus	1.3.6.1.6.3.14.1.2.1.9	RowStatus	read-create	The status of this conceptual row. To create a row in this table, a manager must set this object to either createAndGo(4) or createAndWait(5). The following objects may not be modified while the value of this object is active(1): - snmpProxyType - snmpProxyContextEngineID - snmpProxyContextName - snmpProxyTargetParamsIn - snmpProxySingleTargetOut - snmpProxyMultipleTargetOut
snmpProxyConformance	1.3.6.1.6.3.14.3
snmpProxyCompliances	1.3.6.1.6.3.14.3.1
snmpProxyCompliance	1.3.6.1.6.3.14.3.1.1			The compliance statement for SNMP entities which include a proxy forwarding application.
snmpProxyGroups	1.3.6.1.6.3.14.3.2
snmpProxyGroup	1.3.6.1.6.3.14.3.2.3			A collection of objects providing remote configuration of management target translation parameters for use by proxy forwarder applications.
