What do switches do?

Here are some facts about switches:

Switches work at Layer 2 of the OSI model, not Layer 1 like a hub

Switches switch Ethernet frames

Switches don’t look at IP address information, only Ethernet MAC addresses

Switches keeps a table of all MAC addresses traversing the switch and what port they are on (this table is called the bridge forwarding table or CAM table)

Switches only sends traffic to the devices that are the destination for that traffic, saving bandwidth

Each device connected to the switch gets the full bandwidth of the switch port because the switch prevents collisions

Flooding
Now that you know that the switch has the bridge forwarding table and uses that to intelligently send traffic, a common question is, “what if the destination MAC address for the traffic that the switch receives is not in the bridge forwarding table?” What does the switch do with that Ethernet frame? The answer is that the switch will flood that frame out all ports on the switch. The switch will then monitor the traffic for the response from that frame and see what device, on what port, responded to that flooded frame. That information will be put in the bridge forwarding table so that, next time, the switch won’t have to flood that traffic.

Bridge forwarding table
To see the bridge forwarding table on a Cisco switch, just type show mac-address-table, like this:

Port speed & Duplex
Of particular importance when it comes to switches are port speed and duplex. The speed of a port can be set to 10Mb, 100Mb, or 1000Mb (1GB), or Auto negotiate, depending on what the switch and the connecting device offers. Most switch ports and devices use auto negotiate to find the best speed and duplex available. However, this doesn’t always work. Some devices have trouble with this and you may have to go in to the switch and hardcode the speed or duplex.

Most business users prefer a managed switch so that you can get statistics on switch traffic, see your bridge forwarding table, troubleshoot connections, and hard-code port speeds and duplex. Conti Networks offers most of these.

There are many brands of managed switches including, of course, Cisco. These managed switches come in sizes from just a few ports, all the way up to over 96 ports. You can even buy chassis-based switches, costing tens of thousands of dollars, like a Cisco Catalyst 6500 series switch. The chassis-based switches can have blades (cards) that perform not just switching but also routing, intrusion detection, and other services.

Another type of switch is called a Layer 3 switch. A Layer 3 switch is a switch that also has the routing functionality of a router but no WAN ports. Layer 3 switches are used primarily when a large company wants to use VLAN’s to segregate their network into logical networks.
