ISE and ACS?

[stewart699700]

Is there any reason why we would need an ACS and ISE, as my understanding is the ISE alone would be sufficient?

We are looking to deploy a wireless network supporting a mixture of corperate device and BYOD.

Corperate users would be required to be Authenticated via AD which I believe the ISE can support.

Other users would be Authenticated via the ISE portal.

Kind Regards

Keep in mind that ISE doesn't do TACACS+, so you can't use it for standard management access and command authorization of Cisco devices as with ACS.

Thanks for that, very good point, but TACACS+ is not required.

Authentication is only required for Wireless users.
