In Cisco land, finding the right switch without any guidance is like wandering into a wild jungle without a map. Cisco is known to have dozens and dozens of variations of the same switch in the same line of switch. For example, even though WS-C3560X-48T-L and WS-C3560G-48TS-S are both in the same Catalyst 3560 family, the X is vastly superior than the G in terms of forwarding bandwidth. And this often times make our clients confused as to what is the exactly the difference between the two. With any other manufacturer, a huge difference in forwarding bandwidth usually makes them completely different tiers of switch by one using a completely different number, and not some variations of the number.
Whatever it is that Cisco does not want to or not able to use a different number due to other products occupying the space, client should be extremely tentative when buying Cisco’s Catalyst switches. Even with just a tiny letter change, it could mean the right switch or a completely incompatible switch. Today, we’ll examine the difference in the X and G version of the 3560s.
