C240 nic

[David McMullen_1]

I am plugged into a 10MB HALF Duplex port. I set the speed to 10 and the Duplex mode to HALF. I get the following message.

ERROR: invalid duplex value for interface

I set the Autoneg to ON and I get the same error.

In my NIC settings under SAM I have 2 lines, one with:

Fast Ethernet lan0 8/0/20/0 Enabled 10.120.33.135

and 1 line with just the word DISABLED under status.

Any idea why this is happening?

TIA

What happens if you do not set the duplex? Isn't 10Mb half duplex by default?

What does the config file for the lan card in /etc/rc.config.d show? Does the card get set correctly when you reboot the machine?

hpbase100conf has the following:

HP_BASE100_INTERFACE_NAME[0]=lan0
HP_BASE100_STATION_ADDRESS[0]=0x0060B0D053A4
HP_BASE100_SPEED[0]=10HD
#HP_BASE100_DUPLEX[0]=

I would like to go to 100mbs FULL duplex but I cannot make the change effective.

David, if you have applied patches, then trash your hpbase100conf file and copy this over:
cp /usr/newconfig/etc/rc.config.d/hpbase100conf /etc/rc.config.d

Just include the interface name and speed (you don't need the station address), then run
/sbin/rc2.d/S###hpbase start

Make sure it is plugged into a switch that is running full duplex and 100mps if you want it to run 100FD.

david -

if the port you are plugged-into is 10Mbit HD, then you have to switch it to 100FD (assuming that is possible) before you can switch the NIC to 100FD.

if the switch does support auto-negotiation, you might simply set the switch to autoneg and the NIC to autoneg. my _personal_ preference is to go with autoneg until such time as I _know_ there are negotiation problems. hardcoding NICs and ports requires careful memory - especially if someone is likely to move cables around - duplex mismatch can ruin your whole day.
