Built-in LAN speed and duplex mode question

[Sarah Reed]

What duplex modes (half or full) will the Built-in LAN interface support on the older models, specifically the E45, H Class, and K-class?

Is the Built-in LAN interface for the E class, H class and K class always 10 Mbs/half duplex (full duplex is not an option)?

And finally, if the Built-in LAN interface on these class servers supports full duplex, how does one set the duplex mode on the interface and can you detect/determine the setting from the command line?

lanadmin will tell you all.

# lanadmin -> lan -> display

The first few lines will tell you all you want to know.

You're right, it's 10Mbs.... there is no such thing as full duplex 10Mbs...try it and see.

We had an incorrect setting on a port on a switch here one day, 10Mbs half duplex. It started to "flap" - in other words the device on that port was constantly joining and leaving the switch group.

Hi Sarah,

10BaseT support onlt 10MBPS half duplex. For more info on 100BaseT and HD/FD, take a look at this thread,

On a lan port supporting FD, you can modify the FD/HD 10/100 options using the "lanadmin" command.

Hope this helps.

Hi Sarah,

All the models that you mentioned are only 10 Half Duplex. They do not support Full duplex.

However there is a thing called 10 Full Duplex!!!!!.
