What Is Wellfleet-AOT-MIB?

Wellfleet-AOT-MIB is a proprietary MIB from Wellfleet Communications (a router vendor that merged into Bay Networks and later Nortel) covering 'Adaptive Optimized Transport' (AOT) parameters and performance statistics on Wellfleet routers. It exposes configuration objects for the AOT feature along with performance counters describing how traffic is being optimized or transported across the link. As a performance-monitoring MIB, it is used to track the software-managed traffic-shaping/optimization behavior of the router -- watching statistics for signs of degraded optimization performance or misconfiguration -- rather than raw hardware sensors like temperature or fan speed. It is part of the larger family of Wellfleet proprietary MIBs (alongside Wellfleet-IF-MIB, Wellfleet-BGP-MIB, etc.) and shares the vendor's common enterprise OID conventions and interface-numbering scheme. It is typically deployed on legacy Wellfleet/Bay Networks routers in WAN environments where AOT-based transport optimization was configured. Engineers can download the Wellfleet-AOT-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in Wellfleet-AOT-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

Wellfleet/Bay Networks router (legacy)

Monitoring Examples

No sample objects were provided for this legacy MIB, so this scenario is inferred from its description: an administrator would poll the AOT performance-statistics objects to track transport optimization throughput or efficiency on a given link. A sustained drop in the reported optimization statistics, without a corresponding drop in underlying link traffic, would suggest the AOT feature has stopped functioning correctly on that interface.

What Can Be Monitored

AOT configuration/administrative state
transport optimization performance statistics
per-link AOT status

INT wfAotDelete	1.3.6.1.4.1.18.3.5.21.1.1	INTEGER	read-write	Create/Delete parameter. Default is created. User perform an SNMP SET operation on this object in order to create/delete AOT
INT wfAotDisable	1.3.6.1.4.1.18.3.5.21.1.2	INTEGER	read-write	Enable/Disable parameter. Default is enabled. User perform an SNMP SET operation on this object in order to enable/disable AOT

INT wfAotInterfaceDelete	1.3.6.1.4.1.18.3.5.21.2.1.1	INTEGER	read-write	Create/Delete attribute. Default is Created Users perform SNMP SET operation on this object in order to create/delete a translation interface record
INT wfAotInterfaceDisable	1.3.6.1.4.1.18.3.5.21.2.1.2	INTEGER	read-write	Enables/Disables this mapping entry Setting of this attribute to DISABLED will disconnect all active sessions pertaining to this interface entry
INT wfAotInterfaceCctNumber	1.3.6.1.4.1.18.3.5.21.2.1.3	INTEGER	read-only	The circuit from which the connection attempt is received that initiates a translation session.
INT wfAotInterfaceSlotNumber	1.3.6.1.4.1.18.3.5.21.2.1.4	INTEGER	read-only	Slot number on which this interface is running
INT wfAotInterfaceState	1.3.6.1.4.1.18.3.5.21.2.1.5	INTEGER	read-only	The current state of the Interface
INT wfAotInterfaceType	1.3.6.1.4.1.18.3.5.21.2.1.6	INTEGER	read-write	If this interface is point-to-point, i.e. no splitting occurs we can straight away deliver PASC frame to designated TCP circuit
INT wfAotInterfaceAttachedTo	1.3.6.1.4.1.18.3.5.21.2.1.7	INTEGER	read-write	Information that this interface is attached to the Primary or secondary PASC station

INT wfAotKeepaliveInterval	1.3.6.1.4.1.18.3.5.21.2.1.9	INTEGER	read-write	Idle session timeout period, in seconds. If an established TCP connection remains inactive for this interval, KEEPALIVE messages will be sent to the peer (if the Keepalive Timer is non-zero). Setting the Idle Timer to zero disables the keepalive feature.
INT wfAotKeepaliveRto	1.3.6.1.4.1.18.3.5.21.2.1.10	INTEGER	read-write	KEEPALIVE retransmit timeout period, in seconds. This is the interval at which unacknowledged KEEPALIVE messages will be retransmitted. If the Idle Timer is set to zero, this timer ignored. If the Idle Timer is non-zero and this timer IS zero, no KEEPALIVEs are sent and the session is terminated upon expiration of the Idle Timer.
INT wfAotKeepaliveMaxRetry	1.3.6.1.4.1.18.3.5.21.2.1.11	INTEGER	read-write	Number of unacknowledged KEEPALIVE messages retransmitted before the TCP session is terminated. If this count is set to zero, only one KEEPALIVE message will be sent.
