Initial Configuration of the NIC

The network adapter can be brought up for use with the "plumb" switch in the ifconfig command. This is done by using:

ifconfig <NIC> plumb (or deplumb for the reverse)
ifconfig <NIC> ip <ip address> netmask <subnet mask> broadcast <broadcast address>
ifconfig -a {verify the NIC properties} 

Setting NIC speed and duplex

Solaris is often unable to correctly auto-negotiate duplex settings with a link partner (e.g. switch), especially when the switch is set to 100Mbit full-duplex. You can force the NIC into 100Mbit full-duplex by disabling auto-negotiation and 100Mbit half-duplex capability.

Check Current State

To check the link status for every available network adapters on the system, as root use:

dladm show-dev
netstat -in # shows packet information, look for the Collis (Collisions) column, if there is anything more than 0, then you know there is a problem

Test with Live Change

Make the changes to the running system as a test.


 

nestat -an # to determine your interface name, in this example it is bge0}

# You run these command only on the console.

ndd -set /dev/bge0 adv_100hdx_cap 0
ndd -set /dev/bge0 adv_100fdx_cap 1
ndd -set /dev/bge0 adv_autoneg_cap 0 # people on the internet seem to indicate that we should use autoneg_cap last

Make the Changes Permanent

Full confusing details from Sun here, http://docs.sun.com/app/docs/doc/805-4449/6j47dm3ih?l=en&q=system+hme&a=view.

To set parameters so they remain in effect after you reboot the system there are at least 3 ways of doing so,

  1. Use a boot script using ndd - can specify particular device.
  2. Edit /kernel/drv/[device name].conf  - Solaris 10 only. Looks like effects all devices.
  3. Configure /etc/system - effects all devices in the system.

There are different types of devices,

  • hme interface
  • eri interface
  • ce interface
  • bge interface
  • e1000g interface

Researching..

******************************************************** content below still being finalized ***************************
 
vi /etc/system
 
Add to the bottom,
 
set hme:bge0_adv_autoneg_cap=0
set hme:bge0_adv_100hdx_cap=0
set hme:bge0_adv_100fdx_cap=1

Or...
set bge:bge0_adv_autoneg_cap=0
set bge:bge0_adv_100hdx_cap=0
set bge:bge0_adv_100fdx_cap=1

Or...
set bge0:bge0_adv_autoneg_cap=0
set bge0:bge0_adv_100hdx_cap=0
set bge0:bge0_adv_100fdx_cap=1

Or...
set bge:bge_adv_autoneg_cap=0
set bge:bge_adv_100hdx_cap=0
set bge:bge_adv_100fdx_cap=1

 
Ok none of this except the manual method using ndd seem to work on the new T5120 (talk to Dimitri or Dickson Tin)
 

Method 1 (Dickson) - requires a reboot

Modify network configuration file appropriate to your kernel,


cd /platform/`uname -i`/kernel/drv/bge.conf  {the command uname -i shows your kernel name}

* note the filename bge.conf will also depend on the hardware. using dladm show-dev determine the file name to use. For the e1000 then use filename e1000g.conf

This change affects all network adapters of the same manufacturer on the system.
adv_autoneg_cap = 0;
speed = 100;
full-duplex = 1;


Reboot the system,

shutdown -i6 -g0 -y

Method 2 (Dimitri) - works best for live systems

Example with bge0 interface.

1. Make the changes to the running system.

nestat -an {to determine your interface name}
You run these command only on the console.
ndd -set /dev/bge0 adv_100hdx_cap 0
ndd -set /dev/bge0 adv_100fdx_cap 1
ndd -set /dev/bge0 adv_autoneg_cap 0

2. Make kernel parameter changes to preserve the speed and duplex settings after a reboot.

vi /etc/system

Add:

set hme:bge0_adv_autoneg_cap=0
set hme:bge0_adv_100hdx_cap=0
set hme:bge0_adv_100fdx_cap=1

I don't understand below. At this point is not everything done? Tin

The /etc/system settings listed above are in the /platform/sun4u/kernel/drv/bge.conf file
Example: /etc/init.d/nddconfig

The contents of the file should be,

#!/bin/sh
ndd -set /dev/bge0 instance 0
ndd -set /dev/bge0 adv_1000fdx_cap 0
ndd -set /dev/bge0 adv_1000hdx_cap 0
ndd -set /dev/bge0 adv_100fdx_cap 1
ndd -set /dev/bge0 adv_100hdx_cap 0
ndd -set /dev/bge0 adv_10fdx_cap 0
ndd -set /dev/bge0 adv_10hdx_cap 0
ndd -set /dev/bge0 adv_autoneg_cap 0 

Make a symbolic link,

ln -s /etc/init.d/nddconfig /etc/rc2.d/S31nddconfig
dmesg | grep bge0 # Make sure the network card shows up by searching in display message
