If you set the MTU parameter on an ethernet port and the VLAN
created from the ethernet interface, and then restart Oracle VM Server,
the MTU parameter resets to the default value of
1500
.
This issue occurs if the value of the ONBOOT
parameter in the
ifcfg-
configuration file for the ethernet interface is contained within
double quotation marks, for example, interface_name
"no"
. When
Oracle VM Manager creates the
ifcfg-
configuration file for the VLAN, the value of the
interface_name
ONBOOT
parameter is yes
.
When the server reboots, the ONBOOT
parameter
for the ethernet interface does not change, and a discrepancy
exists between the two
ifcfg-
configuration files. As a result, the MTU parameter resets to the
default value of interface_name
1500
.
Workaround: Ensure that the value
of the ONBOOT
parameter in the
ifcfg-
configuration file for the ethernet interface is not contained
within double quotation marks, for example,
interface_name
ONBOOT=no
.
