Description: Extreme Networks MIB providing vendor-specific SNMPv3 configuration objects for user-based security model settings on ExtremeXOS.

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 EXTREME-SNMPV3-MIB?

EXTREME-SNMPV3-MIB is an Extreme Networks vendor MIB supplementing the standard SNMPv3 User-based Security Model (USM) with Extreme-specific configuration objects for managing SNMPv3 users, security levels, and access parameters on ExtremeXOS switches. It exposes SNMPv3 user/security configuration data rather than device performance or fault data — essentially administrative/security configuration state. Its monitoring value is limited to confirming SNMP management-plane configuration and security posture (e.g., which SNMPv3 users exist and their configured security level) rather than hardware or performance health, though a misconfigured entry here could explain why a management station cannot poll the device at all. It explicitly extends the standard SNMP-USER-BASED-SM-MIB (RFC 3414) with vendor-specific parameters. It's typically deployed on ExtremeXOS switches where administrators need to configure or audit SNMPv3 security settings beyond what the standard USM MIB exposes. Engineers can download the EXTREME-SNMPV3-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in EXTREME-SNMPV3-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

No sample objects were provided for this module, so specific object names can't be confirmed; based on its description, an admin auditing SNMPv3 access would typically check Extreme-specific user/security-level configuration objects here, and an unexpectedly weak security level or an unrecognized user entry would signal a security misconfiguration.

OIDs

OID symbolic	OID numeric	Type	Access	Description
extremeSnmpv3	1.3.6.1.4.1.1916.1.23			Extreme-specific SNMPv3 objects
extremeTarget	1.3.6.1.4.1.1916.1.23.1
extremeTargetAddrExtTable	1.3.6.1.4.1.1916.1.23.1.1		not-accessible	This table is an extension to the snmpTargetAddrTable found in the SNMP-TARGET-MIB. It contains Extreme Networks specific objects needed for each management target.
extremeTargetAddrExtEntry	1.3.6.1.4.1.1916.1.23.1.1.1		not-accessible	An entry in the extremeTargetAddrExtTable.
T/F extremeTargetAddrExtIgnoreMPModel	1.3.6.1.4.1.1916.1.23.1.1.1.1	TruthValue	read-write	When this object is set to TRUE, the version of the trap/notification sent to the corresponding management target (trap receiver) will be the same as in releases of Extremeware prior to 7.1.0. Thus, the value of the snmpTargetParamsMPModel object in the snmpTargetParamsTable will be ignored while determining the version of the trap/notification to be sent. When a trap-receiver is created via the RMON trapDestTable or from the CLI command 'configure snmp add trapreceiver ....', the value of this object will be set to TRUE for the corresponding entry in this table.
T/F extremeTargetAddrExtStandardMode	1.3.6.1.4.1.1916.1.23.1.1.1.2	TruthValue	read-write	When this object is set to TRUE, the management target will be treated as a 'standard mode' one, in that any Extreme Networks specific extra varbinds present in a standards-based trap/notification will not be sent to this management target. Only the varbinds defined in the standard will be sent.
INT extremeTargetAddrExtTrapDestIndex	1.3.6.1.4.1.1916.1.23.1.1.1.3	INTEGER	read-only	This object contains the value of the trapDestIndex in the corresponding entry of the RMON trapDestTable.
T/F extremeTargetAddrExtUseEventComm	1.3.6.1.4.1.1916.1.23.1.1.1.4	TruthValue	read-write	This object is used only when sending RMON alarms as SNMPv3 traps. When it is set to TRUE and an RMON risingAlarm or fallingAlarm is being sent for an event, then the eventCommunity in the RMON event table is compared to the snmpTargetAddrName in the snmpTargetAddrTable. The alarm is sent to the target only when the two are the same. This behavior is exhibited only when the snmpTargetParamsMPModel corresponding to the target indicates an SNMPv3 trap. For SNMPv1/v2c traps, the community in the RMON trapDestTable is used for the comparision, which is the 'regular' method, as per the standards. When this object is set to FALSE, then the RMON alarm (if being sent as an SNMPv3 trap) is sent without using the event community for any comparision.
