Other than not being capable of PoE, is the Catalyst 2950 missing anything that a PoE-capable 3560 can provide with regard to Cisco IP telephony? We're considering a Cisco IPT deployment and most of our sites already have 2950 switches. I believe that the 2950 is capable of the QoS necessary for high-quality VoIP, it just can't supply the power. I'm considering using PowerDsine power injectors and leaving the 2950s in place.
[At brand new sites, we'd probably just buy a PoE switch right from the beginning.]
Any thoughts? Does the 3560 have some functionality that we would wish we had if we kept the 2950s?
Layer 3 routing is not there with the 2950 model. Especially if you configure dual vlans for data / voice and want to do intervlan routing , you can have it on the 3560 itself. It all depends on your network design.
You can do pretty much anything you need to do on a 2950 if all you need is layer 2... The various configs are detailed in the QOS SRND and as you can see you can go to some detail (probably more than you intend)...
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
