just wanna ask the question, I have set a data VLAN and voice VLAN on 3650, and give them the SVI IP address - for data VLAN is 10.1.1.1, for voice VLAN is 18.104.22.168
and then I put a DHCP Server to assign Ip addresses to both VLAN. The issue is that DHCP works on assigning data VLAN perfectly, but not voice VLAN. I don't understand.
after that, I just put a router and set a dot1q IP address to voice VLAN, and then the DCHP server can work on voice VLAN. Just want to know, is there something about TFTP server?
