Manualmente: ifconfig $DEVICE 0.0.0.0 up deve remover o IP e deixar a interface em funcionamento.
Algumas distribuições permitem essa configuração estaticamente, outras não.
Talvez você possa configurar um dispositivo bridge em vez disso.
No Arch Linux, tenho uma única interface Ethernet física em 2 VLANs (3 e 7) com endereços IP estáticos para as VLANs e um endereço DHCP para a interface Ethernet 'principal'.
Existe uma maneira de remover o endereço IP da eth0 e ter as VLANs? Ou existe uma maneira de atribuir eth0 a uma VLAN? Eu prefiro que isso seja feito como parte dos arquivos de configuração /etc/netctl ou /etc/systemd/network .
O resultado de ip addr é:
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether 6c:ec:eb:5c:a3:0b brd ff:ff:ff:ff:ff:ff inet 192.168.106.55/24 brd 192.168.106.255 scope global eth0 inet6 fe80::6eec:ebff:fe5c:a30b/64 scope link valid_lft forever preferred_lft forever 3: eth0.7@eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default link/ether 6c:ec:eb:5c:a3:0b brd ff:ff:ff:ff:ff:ff inet 10.0.0.1/24 brd 10.0.0.255 scope global eth0.7 inet6 fe80::6eec:ebff:fe5c:a30b/64 scope link valid_lft forever preferred_lft forever 4: eth0.3@eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default link/ether 6c:ec:eb:5c:a3:0b brd ff:ff:ff:ff:ff:ff inet 192.168.1.7/24 brd 192.168.1.255 scope global eth0.3 inet6 fe80::6eec:ebff:fe5c:a30b/64 scope link valid_lft forever preferred_lft forever
E o resultado de ip -d link é:
