I'm designing a new site for my employer and this is the first time I've been asked to do so since my predecessor left. They are aware of my skills but I'm unsure about 2 things and was wondering if you experts could help me?
1. The new site will be connected to an existing site via Microwave (all layer 2), we're running VOIP phones over the link to a PBX in the other site. Knowing the phones are configured correctly and were using a voice vlan then can I simply use a 3560 or 3750 for the link trusting COS? On the other side is a 4006 running CatOS.
2. The access switches were marked as 3560's by my predecessor, however I'm sure 2960's would do, we only have need for Layer 2 QoS and POE on 24 ports, am I correct in my assumption? I know there are many other factors like port density, SFP compatibility, layer 3 MLS, etc but these are simple access switches with VOIP phones, connected to the core switch (the 3560 or 3750)? via Single Mode Fibre all at Layer 2.
