Hi > Can I connect a 100Mbit NIC to a 10Mbit switch without having to configure > the NIC using mii-tool? mayby though it depends alot on what cards you are using do they auto sense the 10Mbit at the other end or do they try to stick to 100 ? > I am trying to create a network where in the edges are 100Mbit and the > core is 10Mbit as follows: seems strange for a very small amount of extra money you could have a 100Mbit switch in the middle is it really worth the performance difference ? > 100Mbit 10Mbit 100Mbit > |*******| <----------> |*******| <----------> |*******| > switch switch switch > All my network interfaces and switches work at 100Mbit and I am wondering > if I need to buy a 10Mbit switch for the core. I know that i can use > mii-tool to force the NIC to work at 10Mbit, but is it reliable? i still dont clearly understand what you are trying todo if you plug switches together where does linux come into this ? unless you are using linux as a switch which is probably more expensive than using a real switch and you may get worse perfomance as well.
