Hyper V NIC speeds?

killmasta93

Hi,
I was wondering if someone knows what speeds can a NIC run under hyper V? As on pfSense shows no NIC speed im guessing 100? Even though the NIC is capable of 1000

Thank you

should be able to get gigabit speeds, although I suppose this depends on the hypervisor and compatibility. On vmware I run vm's that push 400mbit+ daily.

Thanks for the reply, But when you mean it depends on the hypervisor where should i look for?

Thank you

The virtual NIC's in Hyper-V are 10G and that is what i see in pfSense.
Had it in 2012 R2 and switched to 2016 a week ago.

I use just Hyper-V not Server 20XX… - so no GUI.

To understand Virtual Switch's:

Thanks for the reply, as you say on your console of pfSense it shows the speed duplex but how come on mine it does not? or maybe because you only use Hyper V without gui? as in my case i use Windows server 2012r2 with GUI and shares, IIS, etc

Thank you

MrGlasspoole

You have 2 virtual switches in Hyper-V and two network adapters in your pfSense VM?

I called the switches LAN and WAN to know which one goes outside (to modem).

Ok, this are not "Legacy Network Adapters".
Hm, I guess you did already google for this kind of behavior?

What version of pfSense are you using?

MrGlasspoole

From his screenshot 2.2.6

killmasta93

yep its 2.2.6 and its not legacy

If you have no UI (link speed shows in server UI), you can/have to probably go the powershell route, as with all the non-UI server installations.

Also, you could always just run a test - if your connection is not fast enough for a meaningful test, it should not matter too much? Or just put some machines (e. g. file share) on a different interface for a test.

well the speeds are good, but just wandering what speed i might have? as when you powershell route where would search the command to rehabilitate it on the windows server 2012r2?
