Change the MTU of a Data Interface Using the CLI

You can change the value for a data interface from the or the .

You can use commands to lock and unlock hosts, and to modify the on the hosts.

~(keystone_admin)]$ system host-lock <nodeName>
~(keystone_admin)]$ system host-if-modify <nodeName> <interfaceName> --imtu <mtuSize>
~(keystone_admin)]$ system host-unlock <nodeName>

where:

<nodename>

is the name of the host

<interface name>

is the name of the interface

<mtu_size>

is the new value

For example:

~(keystone_admin)]$ system host-if-modify compute-0 enp0s8 --imtu 1496

Note

You cannot set the on an openstack-compute-labeled compute node interface to a value smaller than the largest used on its data networks.
