Hi all

Does anybody know if 3650/3850 series switches support rolling stack-upgrade feature ?

I don't see it on the configuration guides & it doesn't seem a similar function exist for these new switches.

Thanks in advance !

No, as far as I can see RSU is a feature available in IOS software version 12.2(58) SE.

Here is few other reference talks about RSU on those IOS switch platforms

These 3650/3850 is running on IOS-XE image & that does not support this RSU feature.

Talk to your Cisco SE/AM and ask (or tell) them to raise a Product Enhancement Request (PER) so the developers will get the chance to consider this missing feature.

3650/3850 does not have RSU feature. However, it does have a feature called software install which minimizes the downtime. You still need a downtime enough for the entire stack reload. But you can make the stack ready with the new software and use EEM script to reload certain time.

 

You can refer to the deployment guide for details.
