Fiber-To-The-Home (FTTH) is my service provider. From them, I have 10mbit internet service as well as high definition IPTV service. Each HDTV decoder box creates 20mbit/sec constant throughput.
For probably obvious reasons, I would like to isolate the IPTV traffic onto a separate VLAN so that my data network is not flooded with unnecessary data packets.
First question is whether or not I can do this with the PowerConnect 3024. If not, I guess this is a pretty short conversation.
Second question is if so, how? I'm a computer professional and am relatively technical, but I'm no network expert, so I may need a little jump start.
Any help/advice would be much appreciated.
Thanks.
The technology you're looking for is a vlan protocol grouping, and it's not supported on the PC3024. Our newer switches, (the 35xx, 54xx and 62xx) all support this feature. In a nutshell, it takes a unique identifier for a type of traffic as defined by RFC 1430 and when applied will map this traffic type to a particular VLAN. I'm not sure if your traffic would be on this spec, and you'd likely need a router to communicate back to the outside world again, depending on how it connects to your home.
Thanks for the info. I was afraid that this was going to be the case. Looks like the PC3524 is currently going for $325. I don't really have the money to do this, but I will consider it. Seems like there is still some risk in going this route because it is dependent on the TOS for IPTV is defined.
I have another idea, though. If I could get my service provider to "tag" the IPTV packets with a VLAN number, say "222", I could in theory use my PC3024 to split IPTV traffic onto VLAN 222. Right?
When incoming packets have a VLAN tag, it is my assumption that the switch would route those packets only to the VLAN specified. Therefore, other VLANs created on the switch would not see the IPTV packets. Correct?
