Finding out duplex setting on HP 10.20

[MRSG]

on HP-UX 11.00 we can find out the duplex setting of a lan using #lanadmin -x 0. This is returing no output on my 10.20 server.

Can anyone please let me know how I can find this out?

[Alex Glennie]

lanadmin -x NMID/PPA

* You get the NMID (10.20) or PPA (11.0) for the card by running the lanscan command.

4 maybe ?

Hi,

Do a lanscan and check the no under NM ID. Make a note of this number and use it in lanadmin,

lanadmin -s NM_ID_No

this will display the current speed of the card.

Hope this helps.

Everything that is said above is correct.

I am not sure that lanadmin -x is supported on all cards. For instance some old EISA ethernet cards on D class only go at half duplex. If it replies that the -x option is not supported on your platform then this may be the case.

It may help to check your card specification.

If it still doesn't work then check the contents of /etc/rc.config.d files relating to lan and ethernet configuration, so see what it is trying to set the duplex to on boot-up.

The other thing to check is how your router/switch/hub has negotiated the other end of the connection. If your connection is going diabolically slowly, like 80kb/sec then you may have a conflict of duplex.
