Requirements for the control switch are less stringent than for the experimental switch. The control switch is not required to be able to support the full Gb bandwidth simultaneously over all interfaces. Fewer ports are also required. A 24-port switch is sufficient to support 21 PCs, an interface for the firewall, the web server and the image server. The Reassure control switch is the Cisco Catalyst 2970G-24T, and is much less expensive than the 4948.
