3850-48 XS Boot Issue

I have a 3850-48XS switch that is currently in Install Mode and it everytime the switch is rebooted it comes up to

the switch: mode and I have to enter the boot command to boot the IOS image. Do I need to convert the switch to Bundle Mode and download a .bin IOS image so the switch boots to the # prompt? Right now the boot variable is boot system flash: packages.conf. I appreciate any feedback/assistance.

Re: 3850-48 XS Boot Issue

Hi @johnmike,

 

Your register when restarting is 0x102 and the appropriate register is 0x2102

If it is a register problem, check this link:

Re: 3850-48 XS Boot Issue

Change your switch's confreg value to 0x2102, save it and reload again to check

0x142 means password recovery mode.  

Enter the following commands in enable mode: 

  • no system ignore startupconfig switch all
  • system disable password recovery switch all

Next problem.  The switch has boot up in Bundle Mode.  While running 16.3.7.  

Please convert to Install Mode because there will be some functional limitation when the switch operates in Bundle Mode.

Re: 3850-48 XS Boot Issue

I have changed the Mode from Bundle to Install and changed the
config-register but the 3850 still only boots up to switch:....as indicated
below it says the system is not configured to boot automatically. I
appreciate any additional suggestions/feedback.

The system is not configured to boot automatically. The
following command will finish loading the operating system
software:

boot


switch: boot

Re: 3850-48 XS Boot Issue

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

Re: 3850-48 XS Boot Issue

Installed Boot Mode

You can boot your switch in installed mode by booting the software package provisioning file that resides in

flash.

 

switch: boot flash:packages.conf

 

The provisioning file contains a list of software packages to boot, mount, and run.

 

Bundle Boot Mode

You can boot your switch in bundle boot mode by booting the bundle (.bin) file:

switch:

 

boot flash:cat3850-universalk9.SSA.03.08.83.EMD.150-8.83.EMD.bin

 

The provisioning file contained in a bundle is used to decide which packages to boot, mount, and run. Packages

are extracted from the bundle and copied to RAM. The ISO file system in each package is mounted to the

root file system. Unlike install boot mode, additional memory that is equivalent to the size of the bundle is used when booting

in bundle mode.
