Make 2 VLAN in a 3com switch using only one port to the entire network
I have a 3COM 4200G switch. I need to do 2 VLAN. One VLAN including all ports to use PCs and other VLAN including only one port to use an IP Phone. The problem is that the IP range of PCs and Phones are different and switch has only one port that communicate with all network.
How can I make that traffic of both vlans go to the network using the same port?
