Network interfaces¶
The command network interfaces will display the available network interfaces and their configuration. The hostname can be set or changed with network name <hostname>.
A network interface can be configured or changed as follows:
network <interface-name> <ip> <netmask> <gateway>
For example: network eth0 172.29.89.100 255.255.255.0 172.29.89.1
The IP address can be changed without affecting the netmask and gateway using:
network <interface-name> ip <ip>
For example, network eth0 ip 172.29.89.100.
The system should be rebooted after a network interface configuration or change. In the case of a standalone single-node cluster topology, the system should be provisioned again with the cluster provision command as the final step of the change.
Note
In a clustered environment an IP address change may show the following message:
$ network eth0 178.29.21.253 255.255.255.0 176.29.22.1
This change will require a reprovision. Do you wish to continue [y/n] ?y
Unable to change IP address while clustered.
Please remove host from cluster before changing IP address
To remove the host from the cluster, run the command below on the primary unified node:
cluster del <IP address of node to be changed>
Network routes can be displayed with network routes.
- A new network route can be configured with network routes <network-address> <netmask> <gateway>.
- Network routes can be deleted with network routes del <network-address>.
