Here are the commands that are used to change the speed of
the NIC(Ethernet) card:
Interface
Speed Duplex
---------
----- ------
hme0 100
Mbit/s full
hme1 100
Mbit/s full
hme2 100
Mbit/s full
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.
Example with hme0:
1. Make the changes to the running system.
# ndd -set /dev/hme adv_100hdx_cap 0
# ndd -set /dev/hme adv_100fdx_cap 1
# ndd -set /dev/hme 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:hme_adv_autoneg_cap=0
# set hme:hme_adv_100hdx_cap=0
# set hme:hme_adv_100fdx_cap=1
Note: the /etc/system change affects all hme
interfaces if multiple NICs are present (e.g. hme0, hme1).
The /etc/system settings listed above are not
supported for configuring ce Ethernet adapters during system startup; you may either use
ndd commands in an /etc/rc?.d script or create a /platform/sun4u/kernel/drv/ce.conf file with appropriate settings.
Example: /etc/init.d/nddconfig
#!/bin/sh
ndd -set /dev/ce instance 0
ndd -set /dev/ce adv_1000fdx_cap 0
ndd -set /dev/ce adv_1000hdx_cap 0
ndd -set /dev/ce adv_100fdx_cap 1
ndd -set /dev/ce adv_100hdx_cap 0
ndd -set /dev/ce adv_10fdx_cap 0
ndd -set /dev/ce adv_10hdx_cap 0
ndd -set /dev/ce adv_autoneg_cap 0
# ln -s /etc/init.d/nddconfig /etc/rc2.d/S31nddconfig
$ dmesg | grep ce0

Manually
determining NIC speed and duplex
If you have ce or bge
interfaces, use kstat ce and kstat bge, respectively, to return NIC settings. All other interfaces
may use ndd
to determine NIC settings.
ndd example with hme0, assuming "instance" is 0:
# ndd -get /dev/hme link_mode
Interpretation:
0 -- half-duplex
1 -- full-duplex
# ndd -get /dev/hme link_speed
Interpretation:
0 -- 10 Mbit
1 -- 100 Mbit
1000 -- 1 Gbit
To query a different NIC, such as hme1, set the "instance" to 1, and then perform the link_mode and link_speed queries above.
# ndd -set /dev/hme instance 1
Note: the ndd
commands above must be run as root. Otherwise, you will receive errors such as
"couldn't push module 'hme0', No such device or address."
ce
Ethernet adapters
Older versions of the Sun GigaSwift Ethernet 1.0 driver do
not support the ndd link_mode and link_speed parameters. You may either install the latest Sun GigaSwift
Ethernet adapter patch (111883) or you may use kstat
ce ce_device to get speed and duplex information
for ce
Ethernet adapters.
For example (from http://www.samag.com/documents/s=9142/sam0405l/0405l.htm):
$ netstat -k ce | egrep 'link_speed|link_status|link_duplex'
Interpretation:
link_up - 0 down, 1 up
link_speed - speed in Mbit/s
link_duplex - 1 half duplex, 2 full duplex, 0 down
Host/link
partner mismatch example
A large number of output errors or collisions may indicate a
host and link partner mismatch. The following is netstat
-in output from a
system configured for 100 half-duplex while the switch was configured for
100 full-duplex.
Name Mtu Net/Dest
Address Ipkts
Ierrs Opkts Oerrs
Collis Queue
ce0 1500 192.168.1.0
192.168.1.1 2707133478 25 2895422910
142310052 182856975 0
In this example, the switch was
configured for 100 half-duplex and the system was configured for 100
full-duplex. Note the percentage of Ierrs/Ipkts (~ 1.7%).

Ip-forwarding
IP forwarding allows you to forward all requests coming for a certain port or
URL to be redirected to a specified IP address.
ip forwarding becomes enabled automatically when system detects more then one
interface at the booting time . The file involved is /etc/rc2.d/S69inet .
ipforwarding is on by default but can be turned off by following command :
#ndd -set /dev/ip ip_forwarding 0
Router Configuration
After interfaces and ipaddess have been configured the system needs a default
router which will allow the machine to talk to world outside of local network .
You can specify a particular route for a particular address as in following
example
#route add -net 10.0.0.0 -netmask 255.0.0.0 172.40.30.1 1
if the the destination ipaddess is not defined in this manner system
forwards all requests to the default router .
default route is defined manually by editing /etc/defaultrouter file and
putting router’s ipaddress entry in it. This file is read by /etc/rc2.d/S69inet
file during the booting process and entry added to the routing table .
The route can be defined online also using routeadd command but the changes
will be lost on reboot .To make changes permanent make sure to put an entry in
/etc/defaultrouter.
#route add default 205.100.155.2 1
#route change default 205.100.155.2 1
The 1 at the end is the number of hops to the next gateway.
If an interface is not responding to the network, check to be sure it has
the correct IP address and netmask , network cables are fine .
