Intel 10/100 Port Configuration Commands, Get-port-cfg, Displays the current port configuration

C H A P T E R 3 Console Command Reference

NOTE

Setting a port to full duplex automatically disables flow control. Since collisions don’t happen on a full-duplex link, flow control isn’t possible.

One exception is between two Express 10/100 switches. A special piece of information is added to packets traveling between switches to accom- plish this.

The command displays the following information for each port:

•LAN type: ETH10/100 indicates the port can operate at 10 or 100 Mbps.

•Link status: ON or OFF.

•Physical interface type: TPFD indicates Twisted-pair (TP) Ethernet, Full Duplex (FD) capable.

•Speed select: ASENSE indicates the port auto-negotiates with the device on the other end.

•LAN Speed: LAN_SPEED indicates the speed of the link. By default, all ports are 10 Mbps when no device is attached.

•Full duplex mode: ON or OFF (default).

•Flow control: ON (default) or OFF. If you set a port to full duplex, flow control is automatically turned off (changes take effect after a reset). If you try to set flow control to ON while full duplex is selected, the Console Manager ignores the change on reset.
