I am implementing Office Communication Server and want to try the IP Phones, so I started looking into POE switches. I don't have the correct terminalogy. I am looking at HP ProCurve Switch 3500yl 48 port features, I want to make sure it has the feature I am looking for. What I want is, with connection to a single port in switch, I want to have the laptop and the phone connected. So I believe it is going to give two different IP adresses with one cable. Does this feature have a name? With this I can have twice as many people connected to the swtich.

That's not a feature of a switch.

Some phones have passthrough ports that allow you to chain the computer into the phone into the switch - that's fine.  But the switch doesn't know what's connected on the other end - it knows, potentially, what VLAN a port should be on and what MAC addresses can be found on a given port, but it doesn't care about TCP/IP at all.  If it did, how could you daisy chain multiple switches together?

In Cisco, that's called the Voice Vlan. I don't know if HP supports it. It can be configured manually by using trunking and trunk pruning on a phone and computer that are VLAN enabled. The only reason Cisco can do it is because they use cisco proprietary CDP information to determine VLAN information.

As previously state, this isn't a feature of the switch. The switch will create a trunk to the phone. The phone in turn will have two RJ-45 ports. One labeled "Switch" and the other labeled "PC". Most phones today have the feature. I don't know if it has an actual name though. I would just look for a phone that has the second RJ-45 port.

OH, you're talking about multiple VLAN's per port,  not IP address... ok... that makes more sense.
