What Is USR-TFTP-MIB?

USR-TFTP-MIB is a vendor-specific MIB from CommWorks/3Com for managing TFTP-based file transfer operations used to load firmware images and configuration files onto their carrier gateway equipment. It is expected to expose objects controlling and reporting on TFTP transfer sessions, such as server address, filename, transfer status, and result/error codes for firmware or config downloads. Its monitoring purpose is software/operational status: an operator would use it to confirm whether a firmware upgrade or configuration push completed successfully or failed, which is important for verifying software version currency and catching failed update operations before they cause a device to run stale or corrupted firmware. It is part of the USR/CommWorks enterprise MIB family, working alongside the other USR-* platform MIBs on the same gateway chassis. It is typically deployed in carrier remote-access gateway fleets where centralized firmware/config distribution via TFTP is used for maintenance. Engineers can download the USR-TFTP-MIB file directly to load it into their MIB browser.

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

Monitoring Examples

No sample_objects were provided for this module, so specific object names cannot be grounded; however, based on the module description an operator would typically poll a transfer-status object to confirm a firmware or configuration TFTP download completed successfully, and check an error/result code object when a transfer fails. A device stuck reporting an in-progress or failed TFTP transfer status after a scheduled firmware push would indicate a failed upgrade needing manual intervention.

OIDs

OID symbolic	OID numeric	Type	Access	Description
usrTftp	1.3.6.1.4.1.429.4.24			The commWorks enterprise defined MIB objects for TFTP
STR usrTftpConfigFileName	1.3.6.1.4.1.429.4.24.1	UsrDisplayString	read-only	The name of a ConfigFile to read/write permanent database records. If the value of this object is an empty string, then the TFTP process uses the default name `@file://TftpProcess.cfg'.
USR usrTftpCFMStatusFlag	1.3.6.1.4.1.429.4.24.2	UsrConfigStatus	read-write	Setting the value of this object to `save' causes the values of the TFTP Group to be written out to the current config file, which is stored in the usrTftpConfigFileName object. While the new ConfigFile is being written, the TFTP process will set the value of this flag to `saving''. Any attempts to set the value while it is not `normal' (i.e. the file is currently being written to the ConfigFile) while result in a badValue error being returned. Setting the value to `normal' will result in no action.
usrTftpAccessTable	1.3.6.1.4.1.429.4.24.3		not-accessible	The TFTP access table
usrTftpAccessEntry	1.3.6.1.4.1.429.4.24.3.1		not-accessible
IP usrTftpAccessIpAddr	1.3.6.1.4.1.429.4.24.3.1.1	IpAddress	not-accessible	The IP Address of the station allowed to perform TFTP file transfers.
INT usrTftpAccessStatus	1.3.6.1.4.1.429.4.24.3.1.2	INTEGER	read-write	The status of the entry for this address.
usrTftpClientRequestTable	1.3.6.1.4.1.429.4.24.4		not-accessible	The TFTP Client Request Table
usrTftpClientRequestEntry	1.3.6.1.4.1.429.4.24.4.1		not-accessible
STR usrTftpClientRequestFileName	1.3.6.1.4.1.429.4.24.4.1.1	UsrDisplayString	not-accessible	The name of the file which will either be requested from or sent to the TFTP server.
OCT usrTftpClientRequestServer	1.3.6.1.4.1.429.4.24.4.1.2	OCTET STRING	read-write	The name or IP address of the TFTP server. I name it is a domain name of type DnsName (rfc1611)
INT usrTftpClientRequestAction	1.3.6.1.4.1.429.4.24.4.1.3	INTEGER	read-write	The type of request that will be sent to the TFTP server.
INT usrTftpClientRequestMode	1.3.6.1.4.1.429.4.24.4.1.4	INTEGER	read-write	The mode in which the file will be transferred.
I32 usrTftpClientRequestRexmtTimeout	1.3.6.1.4.1.429.4.24.4.1.5	Integer32	read-write	The retransmission time-out.
I32 usrTftpClientRequestMaxTimeout	1.3.6.1.4.1.429.4.24.4.1.6	Integer32	read-write	The maximum number of seconds to wait for a response from the TFTP server. If this value is reached, the TFTP request will be timed out.
INT usrTftpClientRequestStatus	1.3.6.1.4.1.429.4.24.4.1.7	INTEGER	read-write	The status of this row. Setting this object to enable(2) will cause a request (defined by usrTftpClientRequestAction) to be sent to the TFTP server. Depending on the type of request, this object will then be set to either getting(3) or putting(4). When the request is completed, this object will be set to normal(1) which indicates success. If an error occurred, this object will be set to error(5) and the usrTftpClientRequestErrorString will indicate the type of error.
STR usrTftpClientRequestErrorString	1.3.6.1.4.1.429.4.24.4.1.8	UsrDisplayString	read-only	This object will indicate what type of error occurred when the object usrTftpClientRequestStatus is set to error(5).
