[ovirt-users] Re: Ethernet tools for VM's

The first thing that comes to my mind is to check the network's MTU. By default it is 1500, and I suppose you can go with MTU 9000 Also , check if OS is using MTU 9000 Best Regards, Strahil Nikolov В вторник, 9 юли 2019 г., 9:58:47 ч.

I want to make sure that the negotiated speed, handshaking, etc. are all what I expect them to be from the OS level. *** *Mark Steele* CIO / VP Technical Operations | TelVue Corporation TelVue - We Share Your Vision 16000 Horizon Way, Suite 100 | Mt.

Is there another tool I should be using to display the information for ens3 on this server?
