Does the 3200 router support configuration roll back

[Anonymous]

We are in the process of upgrading several remote sites with fractional T1's (512K) to full T's.  Does the 3200 gen 1 support configuration roll back?

Can the adtran 3200 hold two configurations (old and new) so that if the upgrade goes bad I can roll back to the previous config?

Thanks,

Thank you for asking this question in the support community.  Yes, the ADTRAN units can hold multiple configurations in flash.  To save the current running-configuration as a file in flash do the following:

ROUTER-NAME# copy running-config <filename>

For example, to copy the current running-configuration to a file named "test" the command would be:

ROUTER-NAME# copy running-config test

You can verify this file is on the flash with the command show flash:

ROUTER-NAME# show flash

Files:

2432633 NV3200A-06-04-03.biz

   2032 startup-config.bak

   2032 startup-config

   2032 test

2449496 bytes used, 4130728 available, 6580224 total

If you need to "roll back" and load the previously saved configuration back to the startup-configuration do the following:

ROUTER-NAME# copy <filename> startup-config

Then you would need to reboot the unit (without saving):

ROUTER-NAME# reload

Save System Configuration?[y/n]n

You are about to reboot the system. Continue?[y/n]y

I hope that makes sense, but please do not hesitate to reply to this post with any additional questions.  I will be happy to help in any way I can.

Thank you Levi,

The other question is can I set a timer for the router to rollback to the previous config, since this process will be done remotely.

Or can I tell the router to load the new config on a timed restart, say 10-15 minutes?

This is great information you've provided!

If the current startup-configuration is what you want to "rollback" to (i.e., you made changes to the running-configuration, but did not write them to memory), then you can use the command reload in <delay> (Specifies a delay period in minutes (mm) or hours and minutes (hh:mm) that AOS will wait before reloading).  Since the changes to the running-configuration were not saved to memory, then the previously saved configuration will load when the unit reboots.

The following example reloads the AOS software in 3 hours and 27 minutes:

ROUTER-NAME# reload in 03:27

If you want to load a configuration that has been saved in flash, and schedule to boot to that configuration, the commands are similar to what I mentioned previously:

ROUTER-NAME# copy <filename> startup-config

ROUTER-NAME# reload in <delay>

If this does not answer your question, or you have further questions on this topic, do not hesitate to reply to this post.
