ISSU for Cisco 3850 stack

Post by Roselee » Mon May 12, 2014 1:55 am

I've found somewhere that devices that support SSO/NSF should also receive ISSU support.
Anybody have any idea if the 3850 switch will be on the receiving end of such a feature ?
K-1 already has nonstop-upgrade support for their equivalent switch stacks (must be same OS release though, so not really non-stop) and i find that in today's world, layer 3 stacks without downtime during upgrade are mandatory.
I would really like to see a 3850 stack able to perform updates/upgrades without downtime.
But someone told me that: ISSU is mainly used on the 6500 and 4500 series (VSS) switches and is not supported on smaller switches like 3850s or 3750 switches even when they are stacked.
