Finding NIC speed using dlpi

[Rajesh Jangam]

Hi,

I am trying to get the NIC speed on HP-UX.

I also required the MAC address - I could do
it programatically using dlpi.

Is there a way using dlpi to get the NIC speed?
Any alternate way will also do, provided, it is
programatic.

Thanks in Advance,
Rajesh

IIRC one of the fields of the statistics one can retrieve via DLPI encodes the bitrate of the interface.

Thanks for the pointer Rick.

I used the DL_GET_STATISTICS_REQ
to get the statistics of the nic.

Interpreted the resultant information with
DL_GET_STATISTICS_ACK as -

struct mib_ifEntry

It has a field - ifSpeed.

BTW, I think that may be only 32-bits, which is fine up to 1 gigabit links, but for a 10 gigabit link I'm not entirely certain what it would return :) Perhaps just a value of "10" :)

Hi,

lanadmin -x NIC_ID
will give you the requested.
