What Is CT-FLASH-MIB?

CT-FLASH-MIB is an Enterasys/Cabletron MIB for managing flash memory storage on their switching hardware, covering the flash file system's volumes, stored files, and remote file-operation commands (e.g., transferring firmware images to/from the device). It exposes a flash volume status table, a flash file table listing stored files, and a command interface (flashCmdPath, flashCmdNetAddress, flashCmdVolume, flashCmdOperation) with associated status/error reporting for operations like uploading or downloading firmware images. Its monitoring purpose is squarely hardware/software status: available flash space and volume health, which firmware/config files are stored, and whether an in-progress flash operation (e.g., a firmware upgrade) succeeded or failed via flashCmdStatus/flashCmdError. It relies on standard flash file-system concepts and Enterasys's own command-based MIB pattern used across other CT-prefixed modules. It is typically deployed on Enterasys/Cabletron switches where administrators monitor flash storage capacity and manage firmware image transfers remotely via SNMP. Engineers can download the CT-FLASH-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CT-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.

Enterasys/Cabletron network switch

Monitoring Examples

An administrator would poll flashVolumeStatusTable/flashVolumeStatusEntry to check available space and health of a flash volume, and walk flashFileTable/flashFileEntry to see which firmware or configuration files are currently stored. When initiating a firmware transfer via flashCmdOperation with flashCmdNetAddress and flashCmdVolume set, monitoring flashCmdStatus and flashCmdError would reveal whether the transfer completed successfully or failed partway through.

What Can Be Monitored

flash volume status/free space
stored firmware/config files
firmware transfer command status
flash operation error state

flashVolumeStatusTable	1.3.6.1.4.1.52.4.1.5.10.1.1		not-accessible	This table contains status information on each flash volume.
flashVolumeStatusEntry	1.3.6.1.4.1.52.4.1.5.10.1.1.1		not-accessible	Information on a particular volume.
INT flashVolume	1.3.6.1.4.1.52.4.1.5.10.1.1.1.1	INTEGER	read-only	Uniquely defines a volume.
INT flashVolFiles	1.3.6.1.4.1.52.4.1.5.10.1.1.1.2	INTEGER	read-only	The flash filing system status contains the number of files currently in the volume.
INT flashVolSpace	1.3.6.1.4.1.52.4.1.5.10.1.1.1.3	INTEGER	read-only	This object returns the approximate amount of remaining storage space, in bytes, in the flash filing system.
flashFile	1.3.6.1.4.1.52.4.1.5.10.2
flashFileTable	1.3.6.1.4.1.52.4.1.5.10.2.1		not-accessible	Describes each file in a flash file system volume.
flashFileEntry	1.3.6.1.4.1.52.4.1.5.10.2.1.1		not-accessible	Describes a particular file.
INT flashFileID	1.3.6.1.4.1.52.4.1.5.10.2.1.1.1	INTEGER	read-only	This object contains a volume-unique file id associated with each file.
STR flashFilename	1.3.6.1.4.1.52.4.1.5.10.2.1.1.2	DisplayString	read-only	This object contains the filename of the current file.
STR flashFileVersion	1.3.6.1.4.1.52.4.1.5.10.2.1.1.3	DisplayString	read-only	This object contains the file version number of the current file in the form 'XX.XX.XX', where 'X' is in the range 0-9.
INT flashFileType	1.3.6.1.4.1.52.4.1.5.10.2.1.1.4	INTEGER	read-only	This object contains the file type defined for the file.
INT flashFileSize	1.3.6.1.4.1.52.4.1.5.10.2.1.1.5	INTEGER	read-only	This object contains the size, in bytes, currently allocated to the file.
flashCmd	1.3.6.1.4.1.52.4.1.5.10.3
STR flashCmdPath	1.3.6.1.4.1.52.4.1.5.10.3.1	DisplayString	read-write	Filename requested of the server for a TFTP download or upload.
IP flashCmdNetAddress	1.3.6.1.4.1.52.4.1.5.10.3.2	IpAddress	read-write	IP address of the TFTP server to use with a flash file download or upload operation. If an IP address is not specified, the operation will default to the IP address associated with the runtime TFTP download.
INT flashCmdVolume	1.3.6.1.4.1.52.4.1.5.10.3.3	INTEGER	read-write	Flash volume to contain the file created during a download operation.
INT flashCmdOperation	1.3.6.1.4.1.52.4.1.5.10.3.4	INTEGER	read-write	Operation to perform on the specified flash file. Download and upload operations require that the network. pathname, filename, version, type, and volume be specified. Cleanup does not require any additional information.
INT flashCmdStatus	1.3.6.1.4.1.52.4.1.5.10.3.5	INTEGER	read-only	Status of the download or upload operation. The idle(1) status indicates no operation is in progress. The downLoadActive(3) or upLoadActive(4) indicate a file transfer in progress. The completeError(5) status indicates that a file transfer was started but an error was detected.
INT flashCmdError	1.3.6.1.4.1.52.4.1.5.10.3.6	INTEGER	read-only	If the value of flashCmdStatus is completeError(5), then this object describes the nature of the error.
STR flashCmdFile	1.3.6.1.4.1.52.4.1.5.10.3.7	DisplayString	read-write	Flash filename to perform the specified operation.
STR flashCmdVersion	1.3.6.1.4.1.52.4.1.5.10.3.8	DisplayString	read-write	Flash file version to perform the specified operation in the form 'XX.XX.XX' where 'X' is in the range 0-9.
INT flashCmdType	1.3.6.1.4.1.52.4.1.5.10.3.9	INTEGER	read-write	File type to specify with a flash file created during a download operation.
INT flashCmdSize	1.3.6.1.4.1.52.4.1.5.10.3.10	INTEGER	read-write	Size of the download file. This value allows the flash filing system to initialize an appropriate amount of flash memory prior to the TFTP transfer, preventing a time-out condition during a transfer.
INT flashBlockCount	1.3.6.1.4.1.52.4.1.5.10.3.11	INTEGER	read-only	Current TFTP block count of an active session. If no TFTP transfer is in progress, zero is returned.
