Managing network interfaces

After configuring your node network interfaces, you can bring them up and down, as well as delete logical interfaces, bonds and VLANs.

Prerequisites

A network interface is configured, as described in Configuring node network interfaces.

Limitations

Open vSwitch-based bridge interfaces cannot be brought down or deleted after creation.
You can only delete bonded and VLAN interfaces.

To bring a network interface up

Admin panel

On the Infrastructure > Nodes screen, click the name of the node, go to the Network interfaces tab, and then click the network interface with the Disabled status.
On the interface right pane, click Bring up.

Command-line interface

Use the following command:

vinfra node iface up [--node <node>] <iface>

For example, to bring up the network interface eth2 located on the node node003, run:

# vinfra node iface up eth2 --node node003

To bring a network interface down

Admin panel

On the Infrastructure > Nodes screen, click the name of the node, go to the Network interfaces tab, and then click the network interface with the Connected status.
On the interface right pane, click Bring down.
Click Bring down in the confirmation window.

Command-line interface

Use the following command:

vinfra node iface down [--node <node>] <iface>

For example, to bring down the network interface eth2 located on the node node003, run:

# vinfra node iface down eth2 --node node003

To delete a network interface

Admin panel

On the Infrastructure > Nodes screen, click the name of the node, go to the Network interfaces tab, and then click the logical network interface that you want to delete.
On the interface right pane, click Delete.
Click Delete in the confirmation window.

Command-line interface

Use the following command:

vinfra node iface delete [--node <node>] <iface>

For example, to delete the network interface eth2.100 located on the node node003, run:

# vinfra node iface delete eth2.100 --node node003
