Cisco Switches
Cisco’s Catalyst switch line is a highly-advanced line of switching solutions that
scale to meet various business needs, from small organizations to multinational
corporations. Catalyst switches operate at Layer 2, but Layer 3 switching is also
possible with a Route Switch Module (RSM). All of the switches in the Catalyst
line support AVVID networks, including IP phones, but specific switches within
the product line are designed specifically to meet the needs of IP telephony,
specifically inline power, which we will discuss in the next section, and gateway
functionality.We will discuss three lines that meet this challenge: the 3500, 4000,
and 6000 Series.
