7.4 Troubleshooting Application Software Upgrade
Symptom:
When upgrading the VRP software using the TFTP approach, the system displays the
following message:
Starting the TFTP download...
Then the router reboots automatically.
Perform the display version command; then you can see that software verison does
not upgrade.
Solution:
The symptom described above means that the new software version does not load.
Do the following:
z Check the TFTP server to see whether information can be sent. If not, the problem
is likely to result from an incorrectly-configured TFTP server IP address. In this
case, make sure that IP address of the TFTP server is the IP address of the
network interface on the PC, to which the Ethernet interface is connected. (For the
procedure of selecting an Ethernet interface for TFTP upgrade on AR 28 Series
Routers, refer to section
6.1.2 IV. “Upgrading the application image through
Ethernet.”)
To check the IP address of a PC in a Windows environment, do the following:
In Windows 95/98/ME environment, perform the winipcfg command.
In Windows 2000/XP/2003 environment, perform the ipconfig command.
z If Windows prompts IP address conflict, it is very likely that the IP address of the
TFTP server was incorrectly assigned to the upgrading Ethernet interface on the
Router.
z Check the TFTP server. If it prompts a file locating failure, check whether the path
set on the TFTP server and the file name (including the extension) of the
application software set on the router are correct.
Upgrade the application software again after solving the problem.
