Switches: The Current Range

The current Cisco range of switches represents the most powerful yet. Many of them have
layer 3 switching capabilities in addition to layer 2, which means that they can almost be configured
as a multi-port router. Many also run a version of the IOS as standard. The only two
still running the set-based CatOS have an upgrade path to allow them to run IOS. Despite figuring
in the current exam, CatOS is doomed.
This next section looks at the four main switch families in turn, and links together the technologies
we have discussed so far in this chapter with the real world of Cisco products.
