What Is ASCEND-FLASH-MIB?

ASCEND-FLASH-MIB is a vendor-specific MIB from Ascend Communications (later Lucent) that manages the external flash memory ('socket') subsystem on MAX TNT, APEX, and Stinger access platforms running TAOS. The flashDeviceTable reports per-socket capacity and state — flashDeviceSize, flashDeviceUsed, flashDeviceState (inserted/removed), flashDeviceMaster, and flashDeviceFormatStatus — while the flashFileTable lists individual files per socket with flashFileSize, flashFileStatus (valid/invalid/open-read/open-write), checksum, version, and timestamp; a separate flashOperation group (flashOperationStatus, flashOperationCommand) drives and reports on format-card, TFTP upload/download, and config load/save operations, including a large set of TFTP- and flash-specific error codes. Because it exposes both capacity/state and live operation status, this MIB is useful for monitoring flash utilization (comparing flashDeviceUsed against flashDeviceSize), confirming a flash card is inserted and correctly formatted before a firmware or config transfer, and catching failed TFTP transfers via the detailed flashOperationStatus error enumeration. It depends on the parent ASCEND-MIB's flashGroup subtree and standard RFC1155-SMI/RFC1213-MIB imports, and is deployed on legacy Ascend/Lucent WAN access shelves that store firmware images and configuration files on removable flash cards; administrators can download the ASCEND-FLASH-MIB file to load it into their MIB browser when auditing flash storage on these platforms.

IPNetwork Monitor allows you to monitor SNMP objects defined in ASCEND-FLASH-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

Ascend/Lucent MAX TNT, APEX, and Stinger access platforms (TAOS)

Monitoring Examples

An operator polls flashDeviceUsed against flashDeviceSize for a given flashDeviceSocket and checks flashOperationStatus after initiating a tftp-upload; an errorTftpEtimeout or errorFlashResultNoSpace status would indicate the firmware transfer failed due to a network timeout or insufficient flash capacity.

What Can Be Monitored

flash device capacity used/free
flash device inserted/removed state
flash format status
flash file status (valid/invalid/open)
flash file checksum and version
TFTP/flash operation status and error codes

INT flashDevices	1.3.6.1.4.1.529.22.1.1	INTEGER	read-only	The maximum number of flash devices that are presented in the flashDeviceTable. The maximum flashDeviceSocket. A value of 0 indicates that the agent does not support any flashDevices
flashDeviceTable	1.3.6.1.4.1.529.22.1.2		not-accessible	This table contains one entry for each flash socket being mangaged via SNMP agent in this system.
flashDeviceEntry	1.3.6.1.4.1.529.22.1.2.1		not-accessible	An entry in the flashDeviceTable. For each managed flashDevice there is one entry present. It provides information for a single flashDevice as indexed via the flashDeviceSocket.
INT flashDeviceSocket	1.3.6.1.4.1.529.22.1.2.1.1	INTEGER	read-only	A value that uniquely identifies a single entry in the flashDeviceTable.
INT flashDeviceController	1.3.6.1.4.1.529.22.1.2.1.2	INTEGER	read-only	Uniquely identifies the controller that manages this flash device. One or more devices can be managed by a single controller. The devices managed by this agent might have one or more controllers associated to them.
INT flashDeviceControllerSocket	1.3.6.1.4.1.529.22.1.2.1.3	INTEGER	read-only	Identifies the socket of the flashDeviceController for this flashDeviceSocket. One or more sockets can be managed by the controller identified via flashDeviceController. Each socket of a given controller has a unique flashDeviceControllerSocket.
INT flashDeviceSize	1.3.6.1.4.1.529.22.1.2.1.4	INTEGER	read-only	The maximum number of bytes this flashDevice can store.
INT flashDeviceUsed	1.3.6.1.4.1.529.22.1.2.1.5	INTEGER	read-only	The Total number of bytes currently stored in this flashDevice.
INT flashDeviceState	1.3.6.1.4.1.529.22.1.2.1.6	INTEGER	read-only	The current state of this given flashDevice.
T/F flashDeviceMaster	1.3.6.1.4.1.529.22.1.2.1.7	TruthValue	read-only	Identifies if this entry is controlled by the master controller or a slave controller. flashDeviceMaster is true if this socket is managed by the master controller and false otherwise.
INT flashDeviceFormatStatus	1.3.6.1.4.1.529.22.1.2.1.8	INTEGER	read-only	The format present on the flashDevice.
STR flashDeviceDescription	1.3.6.1.4.1.529.22.1.2.1.9	DisplayString	read-only	Textual description of the flashDevice.
flashFileTable	1.3.6.1.4.1.529.22.2		not-accessible	Contains information about all files that are managed via the agent on this system.
flashFileEntry	1.3.6.1.4.1.529.22.2.1		not-accessible	Information about a single file on a given socket. A socket is a single access entity.
INT flashFileIndex	1.3.6.1.4.1.529.22.2.1.1	INTEGER	read-only	The unique index for a given socket that identifies this file.
INT flashFileSocket	1.3.6.1.4.1.529.22.2.1.3	INTEGER	read-only	The socket on which the file resides.
