RHEL 6.1, Centos 6.1 – Configurações de Rede, nome das interfaces | Clécio Oliveira

RHEL 6.1, Centos 6.1 – Configurações de Rede, nome das interfaces

Olá pessoal, em alguns sistemas os nomes das interfaces de rede mudaram.
A partir da versão 6.1 do RHEL e do CentOS 6.1  é em1, para interfaces Gigabit.

Sendo assim, eth0 = em1, eth1 = em2, e assim por diante.

Para Intel X520 10 Gb o nome das placas de redes são:

p3p1, p3p2, p4p1, p4p2 e assim por diante.

Para configurar a interface, edite seu arquivo de configuração:

ifcfg-em1 para a primeira interface de rede e ifcfg-p3p1 para a primeira interface X520 Intel.

O arquivo de configuração de dispositivos de rede está localizada em:

/etc/sysconfig/network-scripts/

Exemplo de configuração do arquivo ifcfg-em1:

vim  /etc/sysconfig/network-scripts/

DEVICE = "em1"
HWADDR = "xx:xx:xx:xx:xx:xx"
NM_CONTROOLED = "yes"
BOOTPROTO = "none"
ONBOOT = "yes"
IPADDR = "10.0.1.20"
NETMASK = "255.255.255.0"
USERCTL = "no"
GATEWAY =

Para configuração via DHCP:

HWADDR = "xx:xx:xx:xx:xx:xx"
NM_CONTROOLED = "yes"
BOOTPROTO = "dhcp"
ONBOOT = yes

Parâmetros:

ONBOOT =
yes - Ativar no momento da inicialização.
no - Desativar no momento da inicialização.
BOOTPROTO =
none - Nenhum protocolo de tempo de inicialização deve ser usado.
bootp - O protocolo BOOTP devem ser usados.
dhcp - O protocolo DHCP deve ser usado.
