Cannot set mtu as permanent on bond interface

1878769Mar 19 2015 — edited Mar 21 2015

Hi,

I've a problem on setting MTU on a bond interface (Oracle Linux 7 with last updates).

I'have a HP FlexFabric 10Gb 2-port 526FLR-SFP+ Adapter; I've created a bonding within the two ports (802.3ad mode) and it works.

I'd like to set permanent MTU size to 9000, but I'm unable to do this; I've modified the specified bond interface in /etc/sysconfig/network-scripts/... with te line:

MTU=9000

but at next reboot MTU remains at 1500.

I've tried to set MTU=9000 in slave interfaces and in te physical interface config script, with no luck (mtu remains 1500).

The only way to set MTU=9000 is using ifconfig command:

ifconfig bond0 mtu 9000

but it's a temporary setting.

Doeas anybody knows where I'm wrong?

The server is a new Hp Proliant that is supported in Operating system matrix for Oracle Linux 7.

Thank you very much, any help would be appreciated.

Marco
