Screen OS

SSG-5-sh loops all the time in startup,

What can I do ?

I already upgrdade Bootloader and Screen OS but it does not help

If you upgrade ScreenOS Version from lower 6.3 to 6.3.x you must deactivate DHCP-Server. When the DHCP-Server is activated at booting the SSG boot process loops.

If you can't deactivate the DHCP Server before the upgrade then do following.

Copy the command line STRG-C:

unset interface bgroup dhcp server service 

After the SSG reboots you have some seconds to login and to paste the command with STRG-V. After that the SSG will not reboot. Save the configuration with save. Now you can add a new DHCP configuration.

We have the problem with upgrades to 6.3.0r21.0 from lower versions. If you deactivate the DHCP Server before the upgrade everything is fine.

Hi,

Thank you for your answer.

Deactivating before upgrade is not possible anymore.

But you speak about putting the command for deactivating DHCP

but where ?

I do not see where I can log in ?

Please open a case with JTAC for assistance.  It might be a different issue than with the DHCP server.

I would like to try first the DHCP solution ,

but I do not understand how to do 

The device is working now.

Special thanks to Mr. Ralf Zimmermann.
