Alcatel Unleashed

Hi ,

How can I upgrade firmware on Alcatel 6850 model on a stack environment using usb ? What are the steps I need to know ?

Thanks in advance .

Regards,

Woowar.

did you read the manual?

thanks.

regards.

yes I did.

1.FTP the following 6.4.4.R01 image files to the /flash/working directory of the primary switch:
K2os.img, Kadvrout.img, Kbase.img, Kencrypt.img, Keni.img, Ksecu.img.
2.-> reload working no rollback-timeout.
3.-> copy working certified

Are these steps the same for stack environment ?

Regards,

Dear Woowar,

Please use ->rls X /flash (X = stack number), check if there are any Crash.pmd or other need not files.
If those unwanted file exist, may occur low flash state, you might not able to proceed reboot or write-memory command.
Worst case, some of the stack might still remain old version AOS.

Normally, I will use rls and rrm to check and remove unwanted files, to make sure flash has enough space.

In stack environment you will need extra "copy flash-synchro" command to make your switch synchronized.

Wish you good luck, have a nice day.

Best regards,
Andy

dogx is right, this may be very relevant if you have 6850 without E - as this switches only have 64MB flash. in this case i would check whether you need the advanced routing - if you do not use OSPF/BGP aso. you can remove kadvrout.img from working and certified and do not need to copy that files - spares you 6MB.

For USB Upgrade:
write memory flash-synchro
usb enable
usb auto-copy enable
(given that you have the correct directory structure on your USB)

But this does nothing else than copyiing to working and reloading the switch (at that point it will sychronize to all other stackmembers)
afterwards do another
"write memory flash-synchro"
to certify the stack.

Thanks Andy and Devnull.
