STEPS
Speed: Auto
Duplex: Auto
Flow control: On for full duplex and off for half-duplex
If the P841C's auto-negotiation is turned off, an Ethernet port uses the pre-configured speed and duplex
mode when making a connection, thus requiring you to make sure that the settings of the switch Ethernet
port are in the same order to connect.
