x520-sr2 jumbo_frames support

Dear Experts,

I have 3 x520-sr2 on a server and assigned vm 6 VF (2ports x 3).

I bonded 6 virtual nics into bond0. (bonding )

But the result which is not my expect. Slow~

So I googled website and found mtu is the key.

I want to enable jumbo frames by 'infconfig bond0 mtu 9000'.

but error ocurr.

"SIOCSIFMTU: Invalid argument"

I thinks can't over mtu 1500.

How enable jumbo_frames?

Sorry my poor english...

Thanks for visiting our forum and using The Intel X520 Ethernet adaptors. Unfortunately the X520 does not support Jumbo Frames when using SR-IOV.

I am putting the finishing touches on a white paper (which I will publish here) on bonding with SR-IOV, should be available in a couple more weeks.

If you explain how you have the bonding setup, and what you are trying to accomplish, we may be able to offer some advice.

thanx,

Patrick
