What Is Juniper-AUTOCONFIGURE-MIB?

Juniper-AUTOCONFIGURE-MIB is a Juniper Networks enterprise MIB managing automatic subscriber interface configuration (auto-sensing encapsulation) on Juniper E-series broadband access routers. It exposes a per-interface table covering whether auto-configuration is enabled, the detected/negotiated encapsulation type, and a lockout mechanism with configurable minimum/maximum lockout durations, elapsed lockout time, and the next scheduled lockout time. Its monitoring focus is software/configuration-state health of subscriber-facing interfaces: confirming auto-configuration is enabled where expected, and detecting an interface stuck in a lockout state (which would prevent new subscriber sessions from establishing on that interface), a useful early signal of a misbehaving or flapping subscriber line. It is Juniper-specific and works in concert with JUNIPER-SUBSCRIBER-MIB for the subscribers ultimately provisioned through auto-configured interfaces. It is deployed on Juniper E-series broadband edge routers handling PPPoE/DHCP subscriber connections in ISP access networks. Engineers can download the Juniper-AUTOCONFIGURE-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in Juniper-AUTOCONFIGURE-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 administrator walks juniAutoConfTable (juniAutoConfEntry) per juniAutoConfIfIndex to confirm juniAutoConfEnable is set and juniAutoConfEncaps matches the expected encapsulation for that access line. If juniAutoConfLockoutSupported is true, juniAutoConfLockoutElapsedTime approaching juniAutoConfLockoutTime (bounded by juniAutoConfLockoutMin/Max) signals an interface is in a penalty lockout, likely due to repeated failed auto-configuration attempts from a misconfigured CPE. juniAutoConfNextLockoutTime tells the operator when the interface will next accept auto-configuration attempts, useful for scheduling a manual intervention.

What Can Be Monitored

OIDs

OID symbolic	OID numeric	Type	Access	Description
juniAutoConfMIB	1.3.6.1.4.1.4874.2.2.48			The Auto-Configuration MIB for the Juniper Networks enterprise.
juniAutoConfObjects	1.3.6.1.4.1.4874.2.2.48.1
juniAutoConf	1.3.6.1.4.1.4874.2.2.48.1.1
juniAutoConfTable	1.3.6.1.4.1.4874.2.2.48.1.1.1		not-accessible	Configures recognition of incoming data encapsulation types that trigger autoconfiguration on an interface. Also, configures the time range that the encapsulation type will be locked-out from recognition in the event of an error in creating an interface of the encapsulation type.
juniAutoConfEntry	1.3.6.1.4.1.4874.2.2.48.1.1.1.1		not-accessible	Configures recognition of an incoming data encapsulation type that triggers autoconfiguration on an interface. Also, configures the time range that the encapsulation type will be locked-out from recognition in the event of an error in creating an interface of the encapsulation type.
NUM juniAutoConfIfIndex	1.3.6.1.4.1.4874.2.2.48.1.1.1.1.1	InterfaceIndex	not-accessible	The ifIndex of the interface to which the autoconfiguration information in this entry applies.
JUN juniAutoConfEncaps	1.3.6.1.4.1.4874.2.2.48.1.1.1.1.2	JuniAutoConfEncaps	not-accessible	The encapsulated protocol type to which the autoconfiguration information in this entry applies.
JUN juniAutoConfEnable	1.3.6.1.4.1.4874.2.2.48.1.1.1.1.3	JuniEnable	read-write	When enabled, permits autoconfiguration of the specified interface when the specified encapsulation is recognized in an incoming data frame.
T/F juniAutoConfLockoutSupported	1.3.6.1.4.1.4874.2.2.48.1.1.1.1.4	TruthValue	read-only	Indicates whether lockout is supported for the specified encapsulation type for the specified interface. If lockout is supported, then juniAutoConfLockoutMin, juniAutoConfLockoutMax, juniAutoConfLockoutTime, juniAutoConfLockoutElapsedTime, and juniAutoConfNextLockoutTime are valid and supported in this entry.
I32 juniAutoConfLockoutMin	1.3.6.1.4.1.4874.2.2.48.1.1.1.1.5	Integer32	read-write	The lower bound, in seconds, of the time range used to specify the duration of the lockout of the encapsulation type from recognition for the specified interface. This only takes effect if juniAutoConfEnable is set to enable for the encapsulation type for this interface. The ability to lockout the specified encapsulation type from recognition in the event of an error in creating an interface of the encapsulation type is enabled by default. The initial lockout duration is this object's value and increases exponentially for each failure that occurs for the specified encapsulation type for the specified interface within the greater of 15 minutes and juniAutoConfLockoutMax. The lockout duration for the specified encapsulation type will not exceed juniAutoConfLockoutMax. If the time between creation errors for the specified encapsulation type for the specified interface is greater than the greater of 15 minutes and juniAutoConfigLockoutMax, then the lockout duration reverts to this object's value. To disable the ability to lockout the specified encapsulation type from recognition in the event of an error in creating an interface of the encapsulation type for the specified interface, the value of this object and juniAutoConfLockoutMax must be set to 0. It is not recommended that this lockout feature be disabled except for debugging purposes.
I32 juniAutoConfLockoutMax	1.3.6.1.4.1.4874.2.2.48.1.1.1.1.6	Integer32	read-write	The upper bound, in seconds, of the time range used to specify the duration of the lockout of the encapsulation type from recognition for the specified interface. This value must equal or exceed the value for juniAutoConfLockoutMin. This only takes effect if juniAutoConfEnable is set to enable for the encapsulation type for this interface. The ability to lockout the specified encapsulation type from recognition in the event of an error in creating an interface of the encapsulation type is enabled by default. The initial lockout duration is juniAutoConfLockoutMin and increases exponentially for each failure that occurs for the specified encapsulation type for the specified interface within the greater of 15 minutes and this object's value. The lockout duration for the specified encapsulation type will not exceed this object's value. If the time between creation errors for the specified encapsulation type for the specified interface is greater than the greater of 15 minutes and this object's value, then the lockout duration reverts to juniAutoConfigLockoutMin. To disable the ability to lockout the specified encapsulation type from recognition in the event of an error in creating an interface of the encapsulation type for the specified interface, the value of this object and juniAutoConfLockoutMin must be set to 0. It is not recommended that this lockout feature be disabled except for debugging purposes.
I32 juniAutoConfLockoutTime	1.3.6.1.4.1.4874.2.2.48.1.1.1.1.7	Integer32	read-only	The time duration, in seconds, currently used to lockout the specified encapsulation type from recognition for the specified interface. The reported value is within the range specified by juniAutoConfLockoutMin and juniAutoConfLockoutMax. A value of 0 indicates that no lockout is occurring for the encapsulation type for the specified interface.
I32 juniAutoConfLockoutElapsedTime	1.3.6.1.4.1.4874.2.2.48.1.1.1.1.8	Integer32	read-only	The elapsed time, in seconds, that the specified encapsulation type has been locked-out from recognition for the specified interface. Its value will not exceed that of juniAutoConfLockoutTime. A value of 0 indicates that no lockout is occurring for the encapsulation type for the specified interface.
I32 juniAutoConfNextLockoutTime	1.3.6.1.4.1.4874.2.2.48.1.1.1.1.9	Integer32	read-only	The time duration, in seconds, that will be used to lockout the specified encapsulation type from recognition for the specified interface for the next event that results in a lockout condition. The reported value is within the range specified by juniAutoConfLockoutMin and juniAutoConfLockoutMax. When juniAutoConfEnable is set to enable, a value of 0 indicates that lockout is prevented from occurring for the encapsulation type for the specified interface (i.e., juniAutoConfLockoutMin and juniAutoConfLockoutMax are both set to 0).
juniAutoConfMIBConformance	1.3.6.1.4.1.4874.2.2.48.4
juniAutoConfMIBCompliances	1.3.6.1.4.1.4874.2.2.48.4.1
juniAutoConfCompliance	1.3.6.1.4.1.4874.2.2.48.4.1.1			Obsolete compliance statement for systems supporting enabling of autoconfiguration operation. This statement was obsoleted when encapsulation type lockout objects were added.
