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.
VTP, Portfast, Spanning Tree and all the other switch related stuff.
