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>
--node <node>
- Node ID or hostname
<iface>
- Network interface name
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>
--node <node>
- Node ID or hostname
<iface>
- Network interface name
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>
--node <node>
- Node ID or hostname
<iface>
- Network interface name
For example, to delete the network interface eth2.100
located on the node node003
, run:
# vinfra node iface delete eth2.100 --node node003
