Auto-MDIX is a technology developed by HP by Dan Dove and Bruce Melvin this technique allow us to use any cable kind Straight-Through or Cross Over in Swish, regardless of the binding with hop or router or a PC because the port will choose automatic which cable is that suits him.
As is well known that the devices on the network Divided into two parts.
MDI ports include computer NIC and the Router ports.
MDIX ports include ports of Switch, hop or bridge.
When we want to associate a MDI Device with a MDIX Device we use the cable of Straight type,
and when we want to link the MDI Device with MDI Device we use than Cross over Cable this story has caused some problems for Melvin in his lab when he was looking for a crossover cable he did not find the Cable.
he asked Dove to find Has a solution.
Dove already developed the Auto-MDIX technology.
Mean Auto-MDIX is a technology or Technical they know the connecting wires for send and receive data
Technical work with Swish regardless you choose Straight or cross over Cable.
This Technical requires two things
Port status Speed
Port mode Auto Duplex
This technique is supported by some Cisco switches in the order 2940, 2970.3750
to Configuration Auto-MDIX are very simple.
