Tenho Ubuntu 11.10 64 bits com uma placa de rede Intel 82578 Gigabit (na verdade duas, mas apenas uma está conectada) que está trabalhando em 100 Mbps e quero que ela funcione em 1000 Mbps, mas não consigo. Como posso descobrir o que há de errado?
Veja o que acontece quando tento definir a velocidade com o ethtool:
# ethtool -s eth0 speed 1000
Cannot advertise speed 1000
Eu também tentei isso e perdi a conectividade de rede:
# ethtool -s eth0 speed 1000 duplex full
Estou ficando sem ideias sobre onde procurar.
Algumas informações:
O servidor está conectado a um roteador Cisco RVS4000 que possui todas as portas ativas configuradas para trabalhar @ 1000 Mbps Full Duplex com negociação automática. Na verdade, há outro servidor conectado a outra porta do roteador, que está funcionando bem a 1000 Mbps.
Informações sobre o servidor com o qual estou tendo problemas:
