| A switch is a layer 2 device and as such works with MAC addresses, NOT IP addresses. An IP address is only required on a switch for management purposes - eg. for snmp and telnet.
A router is a layer 3 device and therefore works with layer3 protocols - ie. IP. In order to get on or off a particular network you need a gateway address - this is the IP address on the interface of the router connecting to that network. A router will have a separate IP address for each link or network connected to it.
hope this helps... |
