Layer 3 switches often sit at the network edge or in the backbone, which is exactly the where enterprises will want to begin their 10 GbE migrations. A good example of how 10 Gigabit might fit in is Netgear’s GSM7328FS. This fully managed switch delivers 24 hot-swappable SFP Gigabit interfaces for fiber connectivity and four copper ports 10/100/1000 Ethernet interfaces. Most importantly for this discussion, the GSM7328FS also features four high-speed bays offering module-based expansion for 10 GbE.
