I am currently running a Cisco VoIP network with VLANs separating the data and the voice traffic. I have a 3650 PoE 24-port Layer 3 switch to handle the routing. I also have four 3500 XL 24-port PoE switches. All the switches are connected via their Gigabit GBIC's. I am looking to add a Gigabit switch to connect all my servers and switches. This switch does not have to support PoE. What are some features I need to look for? This switch does not have to be a Cisco product. It just needs to pass through the VLAN tagging. I'm looking at spending less than $1,000 for this switch. Any suggestions?
