How do you configure voice and data vlans on a Cisco 2950 switch?
I have a Cisco 2950 switch. I am running a data and voice VLAN. I have my last 2 ports set for trunking and I am pulling both vlan information from a 3650 Switch. Right now all my data traffic goes Thurugh but not my voice vlan. Am I doing something wrong?

This is hard to diagnose without being on the switch itself. When you do a “show interface trunk” the trunk shows “up” and that the appropriate VLAN’s are trunking across the interface? If you place a voice device on both switches, and they try to ping one another (this is most easily accomplished with two laptops) does it fail, or does it work? If it fails, you likely have a Layer 2 issue (trunking, VTP, etc.) and if they succeed you have a routing issue (the Data VLAN – which I presume is working fine – has a router associated with it but not the Voice VLAN).
I would need to see configurations and show commands to properly diagnose this problem, but with these ideas above and CCO, I bet you can find where the issue is. Good luck.
