Remove any existing connection profiles for the interface which will have the VLAN(s). Assuming this interface is eth0
:
# for connection in $(nmcli -t --fields name,device connection | awk -F ":" '($2 ~ "eth0") {print $1}') ; do nmcli connection delete $connection ; done
Create a profile for the underlying interface with no IP addressing assigned:
# nmcli connection add type ethernet ifname eth0 con-name eth0 # nmcli connection modify eth0 ipv4.method disabled ipv6.method ignore # nmcli connection up eth0
Create a VLAN on top of eth0 with the IP addressing. The following assumes a VLAN ID of 10. Use either DHCP or set a static IP address:
### Using DHCP for IP addressing: # nmcli connection add type vlan ifname eth0.10 con-name eth0.10 id 10 dev eth0 ### With a static IP of 192.168.1.10/24 and gateway of 192.168.1.1: # nmcli connection add type vlan ifname eth0.10 con-name eth0.10 id 10 dev eth0 ip4 192.168.1.10/24 gw4 192.168.1.1
If using static addressing, you may want to also set DNS name server entries:
# nmcli connection modify eth0.10 ipv4.dns 8.8.8.8
The following instructions assume that eth0 and eth1 are the names of the interfaces to be used as the bond slaves.
# for connection in $(nmcli -t --fields name,device connection | awk -F ":" '($2 ~ "eth{0,1}") {print $1}') ; do nmcli connection delete $connection ; done # nmcli connection reload
# nmcli connection add type bond ifname bond0 con-name bond0 mode active-backup miimon 100 # nmcli connection modify bond0 ipv4.method disabled # nmcli connection modify bond0 ipv6.method ignore # nmcli connection add type bond-slave ifname eth0 con-name eth0 master bond0 # nmcli connection add type bond-slave ifname eth1 con-name eth1 master bond0 # nmcli connection up bond0
### Using DHCP for IP addressing: # nmcli connection add type vlan ifname bond0.10 con-name bond0.10 id 10 dev bond0 ### With a static IP of 192.168.1.10/24 and gateway of 192.168.1.1: # nmcli connection add type vlan ifname bond0.10 con-name bond0.10 id 10 dev bond0 ip4 192.168.1.10/24 gw4 192.168.1.1
# nmcli connection modify bond0.10 ipv4.dns 8.8.8.8
