9500 in stackWise and EWC

[Guillermo_PY]

Hello Team,

Reading the document https://www.cisco.com/c/en/us/products/collateral/wireless/catalyst-9800-series-wireless-controllers/guide-c07-744299.html to implement EWC on 9000 series, I see this note:

Note:       HA SSO is not supported with the Catalyst 9400 Series StackWise Virtual setups, nor with the Catalyst 9500 or 9500H Series

And my question: Is necessary to break the stack on my 9500 to deploy EWC?

Regards

Hi

 No. This means that  If you have 9500 with stackwise you are not going to have HA SSO with EWLC.  That´s it.

You can have EWLC without HA SSO.

Hi @Flavio Miranda 

Only to reconfirm, Is not necessary to break my 9500 StackWise, but my EWLC will be deployed like a Single switch design as mentioned in the document, right?

[Flavio Miranda]

that´s correct.  You can build a HA +1 topology instead.

@Guillermo_PY are you planning to use SDA EWC and non-SDA EWC?

If non-SDA then take careful note of the warning at the top of that doc:

"Embedded Wireless on Catalyst 9000 Series Switch (non-SDA) using WebUI will be End of Support (Q3FY21) with no additional feature development or code changes and 17.3.x is the last supported release."

non-SDA is already end of support and you won't be able to upgrade beyond IOS-XE 17.3.x which is itself approaching end of life.  If using SDA then no problem - that is still supported.

@Rich R  thanks for your good observation. I will keep it in mind.

Yes, I have the intention to use it in non-sda
