Please help me. I have this error when adding the voice vlan on the interface po1

Command rejected: Voice Vlan cannot be configured on this interface

interface po1

Are you trying to configure a Portchannel to connect to a phone? If that is the case, it will not work.

Hello,

the command is accepted on physical RJ45 interfaces .

IF you want to carry the voice VLAN on a port channel configure the port channel as a L2 trunk and add the voice vlan to the list of allowed VLANs.

Hope to help

Giuseppe
