Voice vlan on Nexus 9300

[amit.fernandes]

Hi,

I noticed we cannot configure the voice vlan command on the N9K. Our model is C93108TC-EX. Sw version is 7.0(3)I4(3)

Some other discussions suggested trunking both data and voice vlans? Has anyone tried it ?

Can we try this configuration instead ? 

int e/1

switchport 

switchport mode trunk

switchport trunk allowed vlan <data-vlan>

switchport trunk native vlan <voice-vlan>

Hello,

you need to set the port to trunk mode and allow both the data and the voice Vlan, as in the example below:

Interface e1
switchport
switchport mode trunk
switchport trunk allowed vlan 100, 200

Thansk for the response.

Will the VoIP phone be able to untag the right vlan and assign it to desktop port ? Have you tried this configuration with a desktop attached to a phone ?

it does not support - nexus more of Datacenter switches for Server environment - you looking Enterprise or Campus Lan feature on DC switches.

here is reference :

Thanks for the response. Its a one-off. Looking for a couple of VoIP phone on the DC floor. Not looking for system wide LAN solution.

Has this been tested ?

Will the VoIP phone be able to untag the right vlan and assign to the desktop port on the phone ?

Yes if you go the phones admin settings you can manually set the admin (phone) and pc vlan from the phones UI.
