Port Density
The modular Catalyst 6500 switch shown in the figure can support over 1,000 switch ports.
Modular switches are usually more appropriate in large networks in order to reduce space and power issues
-
Forwarding Rates
Forwarding rates define the processing capabilities of a switch by rating how much data the switch can process per second
-
-
-
Power over Ethernet
This eliminates the need for a power cable to the networked device such an IP phone or wireless access point
-
-
Multilayer Switching
Multilayer switches often support specialized hardware called application specific integrated circuits (ASICs).
