Hi, Amb trying to configure two vlans on a port, one for VoIP and another for data on a SFE2010
I've already configured the port as trunk and settled vlan20 (data) as untagged and vlan30 (VoIP) as tagged.
But the phone - which is connected to the switch and the PC to the Phone- shows "Protocol Application Invalid".
I tried to change the switch the tagged vlan, setting vlan20 as tagged and vlan30 as untagged, but then the Phone doesn't register, doesn't get an IP.
How can I configure both vlans on a interface and tell which one is for data and which for voice?
Regards,
