2.3.26 Automatic Upgrade Failure

Symptom
The FTP/TFTP server for automatic upgrade is set (If the IAD is registered to the UCEMS,
you can specify an upgrade server to the IAD through the UCEMS) and the new version file is
available on the server, but the automatic upgrade is not performed after the interval for
detecting automatic update.
Cause
The possible causes are as follows:
Issue 02 (2012-02-29)
register nms ip : 0.0.0.0
register state : no regist
handshake : on
handshake time : 30 S
register switch : on /*on indicates that the IAD registers to the network management
platform.*/
− If it is set that IAD is registered to the UCEMS through DNS (domain name), ensure
that the configuration on the DNS server in the network is consistent with the domain
name on the IAD.
− If the IAD is set that the IAD does not register with the network management
platform and the automatic upgrade is performed through the FTP/TFTP server, run
the display auto-update command to view the configuration of upgrade server and
ensure that the IP address of the FTP server is correct.
If the fault still exists with the preceding factors excluded, the fault may be caused by
system exceptions. Contact Huawei technical support. For details, see
Technical Support.
Run the display log command in the privilege mode to view the operation log. Check
whether other users send commands that may trigger automatic device reset such as the
reboot command, command for IP address modification, or command for loading
configuration file.
If exceptions occur, run the load command to reload the software.
If the IAD crashes, run the display alarm history all command to view the last alarms
and contact Huawei technical support. For details, see
Support.
