Each desk on a new trading floor has a Cisco IP phone with a PC plugged into its pass-through port. The phone must be authorized with MAB into the voice domain, the PC must pass 802.1X into the data domain, and each needs its own authorization result. Which IBNS 2.0 host mode is designed for one voice device and one data device on the port?
Select an answer to reveal the explanation.
Short Explanation
You need multi-domain authentication: it gives the phone a voice domain and the PC a data domain, so each gets its own authorization result. It’s like giving each device its own lane on the same port.
Full Explanation
Multi-domain authentication (MDA) is designed for a port with one voice device and one data device. It permits the phone to authenticate with MAB in the voice domain and the PC to authenticate with 802.1X in the data domain, with separate authorization results. Multi-authentication supports multiple authenticated data devices and can also support a voice device, so it is not accurate to say it lacks voice/data domains; however, it is intended for cases with multiple data devices. Single-host mode does not authorize both devices, while multi-host mode allows devices to share the authorization of the first authenticated host. Host-mode support and configuration details vary by platform, so consult the guide for the switch in use. Verify the separate voice- and data-domain sessions in the switch's session status output.
