Finding out network setting? 1

[mscim]

How do I find the NIC settings of the following:

1. 10 or 100 MBps ?
2. Full or half duplex ?
3. Auto negotiation ON or OFF ?

I'm using Solaris 8

Here is a nice script that I use to check my settings.

#!/bin/sh
#
# luisla@essiprojects.com
# v.1.1. 2002, July.
#
# Read status and info of the local and configured server interfaces, using
# ndd commands.
#
# Think about root execution (change permisions file).
#
#
# P.e. ndd -set /dev/hme link_speed 1
# ndd -get /dev/hme link_status 0 = link up, 1 = link down
# ndd -get /dev/hme link_speed 0 = 10MBit, 1 = 100MBit
# ndd -get /dev/hme link_mode 0 = half duplex, 1 = full duplex
# ndd -get /dev/hme adv_autoneg_cap 0 = no autonegotiation, 1 = autoneg.
#
# lp_100T4_cap = 100BASE-T4
# lp_100fdx_cap = 100Mbit/sec full-duplex
# lp_100hdx_cap = 100Mbit/sec half-duplex
# lp_10fdx_cap = 10Mbit/sec full-duplex
# lp_10hdx_cap = 10Mbit/sec half-duplex
#
# In Netra servers dmfe interfaces has a physical device in /dev, so
# it's innecessary to make instance of interfaces as usual with hme
# o qfe... BTW, link_speed it's not based in 1 o 0, but in 10 or 100 Mb
# and lp_autoneg_cap doesn't exists...
#

call_interface () {

if [ $# = 2 ];
then
SET=`ndd -set /dev/$1 instance $2`

Thanks. Really appreciate it

 

[mscim]

There is a new issue here. Some of my server don't respond to the

#ndd -get /dev/hme link_status

I get this error: couldn't push module 'hme', No such device or address

Are there any other ways of finding out?

Should I find that I need to thange the configuration, how should I do it?

 

[Annihilannic]

Do those systems have hme cards configured? Type ifconfig -a to find out what they are on that system. Maybe there are some old /etc/hostname.* files hanging around.

Note that some earlier network drivers don't respond to ndd at all (although hme should).

Annihilannic.

 

[julianbarnett]

Are they hme interfaces? You need to set the instance number before doing the get.

i.e. for hme1

ndd -set /dev/hme instance 1
ndd -get /dev/hme link_speed
etc..

for le0

ndd -set /dev/le instance 0
ndd -get /dev/le link_speed
etc..
