[Xen-users] RE: set large mtu on bridged network

["Masroor Vettuparambil" <Masroor.Vettuparambil@xxxxxxxxxxxx>]

Hi all

 

its solved..

Actually mtu of vif0.1 was 1500. So bridge was not allowing to set higher mtu than the lowest mtu of its ports (In my case lowest was 1500).

So I changed vif0.1 to 4k,  now jumbo frames are working.

Subject: set large mtu on bridged network

Hi all,

 

In a bridged setup, how we can set a large mtu(4k) for the interface on domU?

Eventhough 'ifconfig eth4 mtu 4000' command worked in my case, whether it reflect on the actual device?

Moreover I can't set mtu for the bridge as 4k. Setting any value above 1500 mtu shows the following error,

 

xen-152:~ # ifconfig xenbr1 mtu 4000
SIOCSIFMTU: Invalid argument

 

So how to set large mtu in a bridged network on xen?

 

regards

Masroor
