Stack with 6580E and 6850

[jmmcdias]

HI,
We can do a stack with the Omniswitch OS6850E and the OS6850? is the same cable? what is the minimal verson support?

Yes.. you can.
Minimal Version is 6.4.4 (6850E need that), so upgrade your 6850 to the same image (miniboot, bootrom, fpga .. check release notes)
Stackcables are the same (no remotestacking with sfp+ on 68950E thou)
You need to check whether the 6850E are in os6850 compatibility mode -> show stack mode

show stack mode 
 NI     Model Name      Current mode     Saved mode
----+----------------+----------------+----------------
  1    OS6850E-P24X      OS6850E          OS6850E         
  2    OS6850E-P24X      OS6850E         OS6850E

here they are not (OS6850E)

and set it if needed to

stack set slot 1 saved-mode os6850
stack set slot 2 saved-mode os6850

Reboot all 6850E to have the mode change recognized (or reboot entire stack.. )

(or vi boot.slot.cfg)

boot slot 1
boot mode os6850

You will loose the additional "E" Features like vrf aso, but now you have a stacked mixed of old and new switches.

Make your own thread.. and i don't speak french so unless you can formulate in english i unfortunatly can't help you..

I have a stack of 2 os6850's. I need to add a third switch to the stack. When I add the os6850E it does not want to sync. Any ideas on how to force a sync.

What do the console messages tell you?

Points to check:
AOS/Miniboot/FPGA Versions? A running stack with 6.4.4 will probably not work with a 6850E running 6.4.5/6.4.4
-> Downgrade according to release notes, at least same fpga version is needed

Stacking mode the same? you can't mix 6850 and 6850E, if you are running OS6850 you may need to "downgrade" the new switch

# show stack mode
NI Model Name Current mode Saved mode
----+----------------+----------------+----------------
1 OS6850-48 OS6850 OS6850

stack set slot 1 saved-mode os6850 reload

what does "show stack topology" show you?


That should be the main causes. just watch the console of the new device
