How to set full duplex in solaris?

[soap]

Hello Guys,

How to set the network port to full duplex? In the switch already set to Full Duplex.

[ryan1210]

To specify full-duplex mode on full-duplex single-mode and multimode port adapters, use the full-duplex command.
full-duplex

Example

The following example configures full-duplex mode on the Cisco 4500:
interface ethernet 0
full-duplex

I'm also intereseted to know. Is there a configuration file to do it? I want to set it up in boot up.

I believe you can change on /etc/system file.

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).
