Hi,
I am new to voice VLAN. I would like to make the network works like the diagram below. a phone connected to the switch gets a address on VLAN5 and a PC connect to the back of the phone gets an address on VLAN1. There is a DHCP server on VLAN5 on the ASA interface and also a DHCP server on VLAN1 on a DC. I got stuck on how to configure the SG-300 switch. Router is ASA5505 and phone is SPA 525G.
VLAN 1 and VLAN5 can ping each other and both have internet connection. Auto Voice VLAN and Smart Port are enabled on the switch(see attachment).
what i have tried:
if i use VLAN1 as native VLAN for all the ports and tags VLAN5, the phone will get a IP on VLAN1. (all ports are trunk).
If i put Port B and Port C on VLAN5 untagged, the phone will get IP on VLAN5, but the PC attached to it is on VLAN5 also. (all ports are trunk).
Please help. or there is a better way to get this work? should sub interfaces?
