We have a sniffer problem in our quite distributed network, because it is built using hubs. We trying to replace them with switches and as an experiment got outselves a CNET PowerSwitch CNSH-800 switching hub. However, it does not have any kind of programmatic control and learnes MAC addresses itself. I wonder if it is the right thing to use? Could its security be compromised? How (is MAC address spooffing possilble?)? If this switch is not the right thing, then which switch is (for reasonable price)?
