I'm configuring a stack of cisco 3750 switches. I'm not sure which ports I should make trunk ports. I know the uplink ports need to be but should I make the rest of them trunk as well? I have several vlans. For most of the ports I'm going to have either workstations or VOIP phones plug into them. the phones are on a different vlan and get the vlan ID programmed into them. So I can plug either the workstation or the phone into the port and it will be on a different vlan. Also I'm using the cisco network assistant to configure them, where is the setting to make a port a trunk port?
