Solved: Update Cisco switch 3850

JaloudAljaloud1575 · ‎06-21-2021

Hallo,

i have 2 Switch WS-C3850-12XS-S and wanna update them remotly in install mode. But every time i do that, the booting breaks up during updates and i should go to the location to reboot the switch. After reboot the switch, i see the switch take the new version.

But i need to do that remotly, so anyone has this problem?!

The Output is like this :

Switch:

Switch : flash_init
Switch : boot flash:packages.conf

after i do these commands, then the switch take the new version.

my plan to do the update :

1- upload the .bin file to the switch

2- switch# request platform software package install switch 1 file flash:cat3k_caa-universalk9.16.06.07.SPA.bin

3- boot system switch all flash:cat3k_caa-universalk9.16.06.07.SPA.bin

hier should i point to .bin file or to .conf file?!

cat3k_caa-universalk9.16.06.07.SPA.conf

cat3k_caa-universalk9.16.06.07.SPA.bin

4- show boot

Current Boot Variables:
BOOT variable = flash:cat3k_caa-universalk9.16.06.07.SPA.conf;

Boot Variables on next reload:
BOOT variable = flash:cat3k_caa-universalk9.16.06.07.SPA.conf;
Manual Boot = no
Enable Break = no
Boot Mode = DEVICE
iPXE Timeout = 0
A1-SW-L-20-1#wr

5- sh running | in boot

boot system switch all flash:cat3k_caa-universalk9.16.06.07.SPA.conf

please any recommendations

Thanks in advanced

Make sure to have a look at CSCvq53573.

What firmware is the switch currently running on?

If the switch is running on 3.X.X, then the command to unpack the package file is:

software install file flash:cat3k_caa-universalk9.16.06.07.SPA.bin new force verb on-reboot

IF the switch is running 16.X.X then the command should be

request platform software package install switch all file flash:cat3k_caa-universalk9.16.06.07.SPA.bin on-reboot new auto-copy verb

NOTE:

See the option (at the end of both commands) of "on-reboot"? This is a bug (CSCve94966) and is actually "no-reboot". When this option is used in the command the stack DO NOT REBOOT when the unpacking completes.
Do not forget to read the Release Notes.
After the stack has completed the update, do not forget to clean up the flash: request platform software package switch all

JaloudAljaloud1575 · ‎06-22-2021

- > i hav this version : 16.6.6

-> So the new Command should be like this :

request platform software package install switch all file flash:cat3k_caa-universalk9.16.06.07.SPA.bin no-reboot new auto-copy verb

-> After this command which boot variable should i point to it?

because after last command i have 5 new pkg of 16.x.x file and one new conf file of 16.x.x.

no boot system flash all
 boot system switch flash:conf   -> conf is the new file.

Leo Laohoo · ‎06-22-2021

What version are you planning to go to?

Post the complete output to the following commands:

dir
sh boot
more flash:packages.conf | b for NOVA

FYI.... the Switche are now in bundle mode and i wanna upgrade them to install mode and then go to Gibraltar-16.12.5b Version

Leo Laohoo · ‎06-22-2021

Beautiful (sarcasm).
Contents of the directory contains five different firmware and I think the main problem is the inability to perform Install Mode because:

a. No one bothered to either read the error message (that there is not enough flash to unpack the package files); &/or

b. No one bothered to read the Release Notes which specifically states to clean up the flash BEFORE initiating the Install Mode command.

I hope someone actually takes the time to read the Release Notes.

Here is the procedure:

1. Clean up the flash

request platform software package switch all

2. Copy the firmware file into the switch.

3. Initiate the unpacking of the file:

request platform software package install switch all file flash:IOS_filename.bin on-reboot new auto-copy verb

4. Make sure the boot variable string is pointing to the "packages.conf" file:

conf t
 no boot system flash all
 boot system flash bootflash:packages.conf
end
wr

5. Make sure the "packages.conf" contains the new version:

more flash-1:packages.conf
more flash-2:packages.conf

6. Reboot the stack.

7. Clean up the flash again.

request platform software package switch all

JaloudAljaloud1575 · ‎06-22-2021

i did this already with this command fot Test Switche, and about last output i am planning to this ( Clean ) before i do the upgrade.

Switch# request platform software package clean switch all file flash:

i read in Cisco that i should enable auto boot before :

If your switches are configured with auto boot, then the stack will automatically boot up with the new image. If not, you can manually boot flash:packages.conf

switch: boot flash:packages.conf

maybe here is the problem?!

1. Double check the "packages.conf" file has been amended with the correct version: more flash-1:packages.conf | b for NOVA

2. Point the boot variable string to the "packages.conf" file.

conf t
 no boot system flash all
 boot system flash bootflash:packages.conf
end

Cisco siad that i should enable auto boot :

Step 8

If your switches are configured with auto boot, then the stack will automatically boot up with the new image. If not, you can manually boot flash:packages.conf

switch: boot flash:packages.conf

maybe here is the problem?!

No, you are in ROMMON.

What happens if you do this: boot flash:cat3k_caa-universalk9.16.06.06.SPA.bin
