Description: Manages boot loader configuration, firmware image selection, and startup parameter settings on Allied Telesis devices.

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 AT-LOADER-MIB?

AT-LOADER-MIB manages boot loader configuration, firmware image selection, and startup parameters on Allied Telesis devices. It exposes a load table describing the source server, filename, destination, and scheduling delay for a firmware image, plus a load status object. Its monitoring emphasis is on software status during the boot/upgrade process: loadStatus tracks whether a firmware download and boot sequence succeeded, is in progress, or failed, which is critical for confirming a device actually came up on the intended image. It works alongside AT-INSTALL-MIB, which tracks the installed release/patch versions once loading completes. It is used on Allied Telesis network equipment during network-boot or TFTP/FTP-based firmware loading operations. Engineers can download the AT-LOADER-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in AT-LOADER-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

Allied Telesis network equipment (boot loader/firmware-load stage)

Monitoring Examples

loadTable/loadEntry, indexed by loadIndex, exposes loadServer, loadDestination, loadFilename, loadDelay, and loadStatus. An administrator configures loadServer and loadFilename to point at a TFTP or FTP image source, then polls loadStatus to confirm the device successfully downloaded and applied the new boot image rather than stalling or failing partway through the transfer.

What Can Be Monitored

configured load server address
target filename/destination
load delay/schedule
load/boot status (success, in-progress, failure)

OIDs

OID symbolic	OID numeric	Type	Access	Description
loader	1.3.6.1.4.1.207.8.4.4.4.48			To handle upload, object loadStatus is upgraded, as well as the description for objects loadServer and loadFilename.
loadTable	1.3.6.1.4.1.207.8.4.4.4.48.1		not-accessible	The table of load parameters, dynamic and static.
loadEntry	1.3.6.1.4.1.207.8.4.4.4.48.1.1		not-accessible	A single entry of load parameters. This contains the parameters required to perform a load from the router.
INT loadIndex	1.3.6.1.4.1.207.8.4.4.4.48.1.1.1	INTEGER	read-write	There are two sets of load information, dynamic and static. The dynamic information is used once, then cleared. The static information is used whenever the dynamic information is not available. The dynamic information is also used to indicate the current load parameters when a load is in progress.
IP loadServer	1.3.6.1.4.1.207.8.4.4.4.48.1.1.2	IpAddress	read-write	The IP address from which load will load or upload.
INT loadDestination	1.3.6.1.4.1.207.8.4.4.4.48.1.1.3	INTEGER	read-write	The destination of the file loaded, either flash or nvs memory, or undefined.
STR loadFilename	1.3.6.1.4.1.207.8.4.4.4.48.1.1.4	DisplayString	read-write	The file name of the file being loaded or uploaded.
INT loadDelay	1.3.6.1.4.1.207.8.4.4.4.48.1.1.5	INTEGER	read-write	A delay in seconds between the initiation of the load and the start of the load. This allows for time to set up TFTP servers in cases where the terminal and TFTP server are using the same piece of equipment but will not work simultaneously.
INT loadStatus	1.3.6.1.4.1.207.8.4.4.4.48.2	INTEGER	read-write	Status and action object for the load module. The values 1 to 5 are read-only values and reflect the state of the load module. Values 4 and 5 (complete and reset) are 'read-once', that is, if their values are read, either by SNMP or by manager console command, then they will be changed back to idle(1). The action values (6,7,8) cause a start and stop of the load/upload process respectively. Starting the load/upload can only occur if this field has the values 1, 4, or 5. Stopping the load can only occur is this field has the values 2 or 3. Reading the value of the loadStatus after one of actionstart or actionstop has been set will give one of the values 1 to 5. Note: A single exception to the above rules is that if the value of loadStatus is idle(1), then a write of 1 to this variable will succeed without generating an error. This exception is to allow certain SNMP test suites to test this variable without throwing up errors.
