Campus Upgrade from 6800 Collapsed Core with 3850 Access to 9504 as CO

[Ibrahim Jamil]

Hi Freinds

I have an upgrade project in my hands 

Current Campus based on 6800 Collapsed Core with 3850 Access ( where the PC /IP Phone/AP are connected ) in STP-based

we need to upgrade to 9504 as CORE with 9300 PoE + as Access with a VxLAN topology , so how the  PC /IP Phone/AP behind 9300 PoE + behave

Pls Advise for optimal Design as per the Above input

Thanks all

There is no differernce when you Migrating to new Topolgy

is the new Topology is SD-Acess or traditional - if traditionla why are you using VXLAN ?

VXLAN is part of Fabric, this is nothing to do with end  device  PC / Phone and AP - they work as expected.

Only changes if you looking SD-Access - Anycast gateway

But you need to consider how your Migration approach - read below guide :

That is nothing but a layer 2 network and upgrading to a 9500 and 9300 is really overkill/OTT (over the top).  I could get away with a 9300X as core switch (for fibre) and a Catalyst 1000 as an access switch.

Hello Freinds

seems 9300 poe+ didn't support VxLAN :(((( 

Need to  get rid of STP from Access to CORE , need all links FW

seems 9300 poe+ didn't support VxLAN :(((( 

Not sure where this statement come from - you need to give full model of the switch and what License you have on the switch.,

below License guide :

Hello my freind

its C9300-48P with DNA Lic Adv , pls not we are not going to run SDA

[balaji.bandi]

You mean to say you are having License of DNA Advantage, not necessary you need to run DNAC and SD-Accesss - that is License you purchased.
