Importante: Antes de alterar a configuração da placa de rede para full ou half de 10 para 100 ou 1GB, verifique as configurações. No tópico; Script para verificação de configuração da placa de rede ( Modelo Sun Fire ), você poderá pegar o script para verificação da configuração da sua placa de rede.
Lembrando que terá que verificar qual a placa ( ce, qfe, hme e etc ) para realizar a mudança.
Exemplo: Caso sua placa seja: hme1 terá que retirar todas as # como exemplo abaixo:
PATH=/usr/bin:/usr/sbin
case "$1" in
'start')
echo "Implementing Solaris Network Tuning."

#ndd -set /dev/hme adv_100T4_cap 0
#ndd -set /dev/hme adv_100fdx_cap 1
#ndd -set /dev/hme adv_100hdx_cap 0
#ndd -set /dev/hme adv_10fdx_cap 0

Salvar com wq! e executar o script. Segue o script abaixo:

Caso você queira forçar essa configuração sempre na inicialização do sistema operacional, basta fazer o seguinte:
Seu script chama mud_parametro.sh e está dentro do home /export/home/script
Faça o seguinte:
1) cp mud_parametro.sh /etc/init.d/S68net-tune
2) chmod 744 /etc/rc2.d/S68net-tune
3) chown root:sys /etc/rc2.d/S68net-tune
4) ln /etc/rc2.d/S68net-tune /etc/init.d/net-tune
Pronto agora sempre que reiniciar o seu servidor ele subirá com a configuração forçada como você desejou !
