Good morning!
So have two VLANs configured on my switch, the default VLAN for data, and a VLAN2 for voice. I was troubleshooting the VLAN with a laptop and if I tag a port for VLAN 2, I can get network/internet connectivity on the laptop as long as I enable VLAN and set VLAN 2 on the laptop NIC. If I try to put in a Cisco VoIP (SPA501G) on that port, I don't get any connectivity. Going through the configs, the phone pulls the proper VLAN2 network configurations using IP-Helper, but not VLAN information. I've tried enabling CDP but no luck. Any thoughts would be greatly appreciated.
