Description: Manages flash memory storage and firmware image inventory on Cisco SIBU SMB switches such as Catalyst 1900.

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 CISCO-SIBU-FLASH-MIB?

CISCO-SIBU-FLASH-MIB manages flash memory storage and firmware upgrades on Cisco's low-end SMB switch platforms (the SIBU, or Small/Intelligent Business Unit, product line such as early Catalyst 1900 series). It belongs to Cisco's device-management MIB family for entry-level switches and exposes flash size, current firmware version, TFTP-based upgrade parameters, and the status of an in-progress firmware load. Its monitoring value is directly about software status: tracking the installed firmware version, available flash capacity, and whether a TFTP firmware upgrade initiated via csfUpgradeTFTPInitiate is in progress, succeeded, or failed via csfUpgradeFirmwareStatus. It is a self-contained Cisco proprietary MIB with no strong dependency on other standard MIBs beyond basic SNMP conventions. It is typically used by SMB network administrators performing remote firmware upgrades on legacy Cisco desktop/workgroup switches over TFTP. Engineers can download the CISCO-SIBU-FLASH-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-SIBU-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

Cisco SIBU/SMB switches (e.g. Catalyst 1900 series)

Monitoring Examples

Before initiating an upgrade, an administrator would read csfUpgradeFirmwareVersion and csfUpgradeFlashSize to confirm current software level and available space, then set csfUpgradeTFTPServerAddress and csfUpgradeTFTPLoadFilename before triggering csfUpgradeTFTPInitiate. Polling csfUpgradeFirmwareStatus afterward reveals whether the TFTP transfer and flash write succeeded or failed, letting the admin detect a stalled or corrupted firmware upgrade before rebooting the switch.

What Can Be Monitored

installed firmware version
available flash memory size
TFTP upgrade server and filename
firmware upgrade status
flash write mode

How to Use in IPNetwork Monitor

Example using csfUpgradeFlashSize OID:

Select a Cisco SIBU/SMB switch (e.g. Catalyst 1900 series, 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 csfUpgradeFlashSize into the Find box to locate it in the OID tree, then select it and click OK. The size of available FLASH memory in the system, in kilobytes. 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 Integer32-type OID, Value bounds is the most useful condition here — trigger an alert if the value drifts significantly from its normal baseline, since an unexpected change often points to a real underlying issue. Click Finish to create the monitor; you can adjust any parameter later.

OIDs

OID symbolic	OID numeric	Type	Access	Description
ciscoSibuFlashMIB	1.3.6.1.4.1.9.10.45			The MIB module that provides a simple mechanism to support firmware upgrade on Cisco low end devices.
ciscoSibuFlashMIBObjects	1.3.6.1.4.1.9.10.45.1
csfUpgrade	1.3.6.1.4.1.9.10.45.1.1
STR csfUpgradeFirmwareVersion	1.3.6.1.4.1.9.10.45.1.1.1	DisplayString	read-only	Returns the version number of the device system firmware residing in flash. The string has a 'V1.2.3' format.
I32 csfUpgradeFlashSizeEx	1.3.6.1.4.1.9.10.45.1.1.2	Integer32	read-only	The size of available FLASH memory in the system, in kilobytes. For example: 128 equals 131072 bytes (128 bytes times 1024).
IP csfUpgradeTFTPServerAddress	1.3.6.1.4.1.9.10.45.1.1.3	IpAddress	read-write	The IP address of a TFTP server from which a firmware image can be downloaded. The download may be initiated by setting the upgradeTFTPInitiate to upgrade(1), or via an out-of-band management action.
STR csfUpgradeTFTPLoadFilename	1.3.6.1.4.1.9.10.45.1.1.4	DisplayString	read-write	The name of the file containing a firmware upgrade image on the host whose address is given by upgradeTFTPServerAddress. The default value is an empty string, or no filename.
INT csfUpgradeTFTPInitiate	1.3.6.1.4.1.9.10.45.1.1.5	INTEGER	read-write	Setting this object to noUpgrade(2) results in no action. When set to upgrade(1), the switch will attempt to download a firmware upgrade image from the server whose address is given by upgradeTFTPServerAddress. The image is found in the file whose name is given by sibuFlashTFTPLoadFilename. Both sibuFlashTFTPServerAddress and sibuFlashTFTPLoadFilename must be non-empty for the upgrade to proceed. This object always returns noUpgrade(2) when read.
INT csfUpgradeFlashMode	1.3.6.1.4.1.9.10.45.1.1.6	INTEGER	read-write	Indicates whether a newly upgraded firmware version should write to flash. When this object is temporary(2), following a successful upgrade the system will switch to run the new firmware but will not upgrade the new firmware to flash. That means after a power cycle, system will run the firmware residing the flash. When this object is permanent(1), following a successful firmware upgrade, the flash will be upgraded and the system will automatically switch to run the new firmware.
INT csfUpgradeFirmwareStatus	1.3.6.1.4.1.9.10.45.1.1.7	INTEGER	read-only	Status of last upgrade attempt via TFTP: none - no upgrade has ever been attempted since initialization. inProgress - an upgrade is in progress. succeeded - the previous attempt succeeded. failed - the previous attempt failed.
