SD-Access Voice Network Query

KatherineTran — Thu, 20 Oct 2022 11:17:22 GMT

Hi Guys,

I've done quite a bit of research the last few days and trying to draw up a design for moving our voice which is daisy-chained onto SD-Access and struggling with a few questions.

If I want a phone to utilise the voice VLAN (which I presume automatically uses the critical voice vlan [2046] which is configured for all SD-Access switches by default? ) how do I define the IP Pool I want to be the voice network?

I believe I could do it by assigning the IP Pool on the VN as a critical pool network and selecting traffic type as: voice. Would that do the trick?

Hope that makes sense.

Thanks

Hi KatherineTran,

I've recently posted a video of exactly this workflow for SD-Access.

Please refer to the link: https://youtu.be/nUZxVF-bP3k

I believe it covers exactly what you are after.

Just make sure that you assign the "Voice domain permission" checkbox in ISE when you configure the voice AuthZ profile.
You also need reserve an IP Pool for voice and enable it under Fabric - Host Onboarding by assigning the voice IP pool to the VN.

Let me know if that answers your question.

Regards,

Pablo.
