3850 Switch- reload packages.conf after every boot

ashidiablo · ‎07-19-2023

As the title states, after every reboot or power outage our distribution switch that trunks to multiple buildings fails after a reboot or a power outage. I will usually have to go in-person and console in and type in "boot flash:packages.conf" to bring the switch back up. I believe it may be a variable not set, but no idea what to type in IOS to prevent this from happening again. Any help or guidance would be appreciated.

Hello @ashidiablo,

Check the output #show version command.

At the end of that out you should see register configuration ; like this:

Configuration register is 0x102

If your value is something other than 0x102 you have to modify this.

config-terminal mode, and use thee command #config-register 0x102

Thanks for the speedy reply. On the show version, it shows the following:

Configuration register is 0x102

Any other idea what it may be? This is the third time it has happened to me, and every time this switch reboots I usually have 2 other buildings with users go down, so I am open to any suggestions that may make this issue go away.

Hello!

Go to switch and check under show version the line Configuration registry. It should be setup as this:
Configuration register is 0x102

I assume you have it setup to: 0x142 which will skip the startup config.

To fix it use the following:

config-register 0x102

no system ignore startupconfig

My config register is set to 0x102, but I will try the second command you listed.

EDIT:

I went to global config and put in the following:

#no system ignore startupconfig switch all (had to type in switch all since it was stacked). I will run a scream test next week, and if it works I will mark as solved.

Post the complete output to the command "sh romvar".

I feel like this may be the issue. After I put the command sh romvar, I noticed the boot variable set to:

BOOT="flash:cat3k_caa-rpcore.16.12.08.SPA.pkg;flash:packages.conf;"

Is that the issue? It's set to a .pkg file instead of a .bin file? If that's the case I wonder why the switch dropped it's IOS image.

Would the command to fix this is upload a valid .bin file, and type in "boot system flash:correct.bin;packges.conf" ?

Boot should be set only to BOOT = flash:packages.conf;

If you are using install mode ofcourse. If you want to use bundle mode it has to be set to only packages.conf.

There are many things I want to see in the command "sh romvar".

If you are unwilling to provide the output then there is not a lot I can do.

That boot variable string is very wrong and should be removed.

Post the complete output to the command "dir".

ashidiablo · ‎07-21-2023

I am not at the office now, but should the output be "boot=packages.conf" ?

Leo Laohoo · ‎07-21-2023

It should only point to "packages.conf" but that is not just what I am looking for. There are several checks yet.
