Description: Appian Communications protection fiber optic transceiver status and switching management.

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 APPIAN-PFOT-MIB?

APPIAN-PFOT-MIB is a vendor-specific MIB from Appian Communications for managing pluggable fiber optic transceivers (PFOT) used in Appian's OSAP product line, a hardware inventory and configuration module for optical interface modules. It exposes per-slot/per-port transceiver identification and configuration data, including transceiver type, connector type, and vendor part information, plus a traps object for transceiver-related events. Its monitoring value is squarely hardware status: acPfotType and acPfotConnectorType let an operator verify the correct optic is installed, and acPfotTraps signals transceiver faults such as loss of signal, mismatch, or a transceiver being pulled/inserted. It complements the entity-inventory conventions common across the Appian MIB family that identify hardware by node/slot/port. Typical deployment is on Appian OSAP2k carrier-grade access nodes using pluggable optics for fiber-based backhaul or protection switching. Engineers can download the APPIAN-PFOT-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in APPIAN-PFOT-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

Appian Communications OSAP2k platform

Monitoring Examples

An administrator would poll acPfotTable keyed by acPfotNodeId, acPfotSlot, and acPfotPort to inventory installed optics, comparing acPfotCfgType (expected) against acPfotType (actual) to detect a technician having installed the wrong transceiver type. acPfotVendorName and acPfotVendorPartNumber support supply-chain/compatibility audits when troubleshooting an unreliable fiber link. A trap from acPfotTraps would flag a transceiver hardware fault or removal event in real time rather than waiting for the next poll cycle.

connector type
transceiver vendor/part number
transceiver fault/insertion traps

How to Use in IPNetwork Monitor

Example using acPfotConnectorType OID:

Select an Appian Communications OSAP SONET/optical access platform (legacy) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type acPfotConnectorType into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. The current type of connector detected on the tranceiver installed in this port. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is an INTEGER-type OID, Value bounds is the most useful condition here — trigger an alert if the value changes unexpectedly, since an unplanned change usually means the transceiver or cabling was physically swapped. Click Finish to create the monitor; you can adjust any parameter later.

OIDs

OID symbolic	OID numeric	Type	Access	Description
acPfot	1.3.6.1.4.1.2785.2.3.7			Appian Communications Pluggable Fiber Optic Transceiver MIB which contains the configuration attributes for use of pluggable fiber optic transceiver technology in the OSAP product.
acPfotTraps	1.3.6.1.4.1.2785.2.3.7.0
NTF acPfotCfgErrorTrap	1.3.6.1.4.1.2785.2.3.7.0.1			The transeiver type for a port is different than the type configured for use.
acPfotTable	1.3.6.1.4.1.2785.2.3.7.1		not-accessible	A table containing the configuration parameters for pluggable fiber optic transceiver in use on a port. The index keys used in this table (node-id.slot.port) are mapped to ifIndex under the appian(2785).interfaces(4).ifTable(1) group. The configuration table will be automatically created by the module driver, regardless of if a transceiver exists on the port or not.
acPfotEntry	1.3.6.1.4.1.2785.2.3.7.1.1		not-accessible	A row which contains the configuration parameters for an physical port equipped with pluggable fiber optic transceiver technology. These rows are automatically instantiated by default.
ACN acPfotNodeId	1.3.6.1.4.1.2785.2.3.7.1.1.1	AcNodeId	accessible-for-notify	The node id is the id for this specific node in the OSAP ring.
ACS acPfotSlot	1.3.6.1.4.1.2785.2.3.7.1.1.2	AcSlotNumber	accessible-for-notify	The slot number within the chassis where this module entry resides.
ACP acPfotPort	1.3.6.1.4.1.2785.2.3.7.1.1.3	AcPortNumber	accessible-for-notify	The port number on the module which is equipped with a pluggable fiber optic transceiver.
ACP acPfotCfgType	1.3.6.1.4.1.2785.2.3.7.1.1.4	AcPfotType	read-create	The desired configured type of transceiver to be used on this port. By default, set to not-present.
ACP acPfotType	1.3.6.1.4.1.2785.2.3.7.1.1.5	AcPfotType	read-only	The current transceiver type detected on this port.
INT acPfotConnectorTypeEx	1.3.6.1.4.1.2785.2.3.7.1.1.6	INTEGER	read-only	The current type of connector detected on the tranceiver installed in this port.
STR acPfotVendorName	1.3.6.1.4.1.2785.2.3.7.1.1.7	DisplayString	read-only	A string represetning the name of the Vendor that manufactured the transceiver installed in this port.
STR acPfotVendorPartNumber	1.3.6.1.4.1.2785.2.3.7.1.1.8	DisplayString	read-only	A string representing the vendor part number used to identify the transceiver installed in this port.
