Host network outbound error

[JMP-CAUX]

Hi

sorry for my english I hope you understand me.
I got this error on my server hyperv1 on a HP blade server system:



I verified the log on my switch on my server and I can not find anything. who has an idea

Thank you for your help

Hello Jean Marc,

The alarm informs you about the packets that couldn't be transmitted because of errors. Do you constantly see this alarm for your Hyper-V host? How have you configured your networks for this server? Do you have many VMs using this NIC to transmit the data?

Thank you!

thank you for your help

I always have this error on this server. I have a teeming of 4 network cards that make a virtual network. there are 4 vm on this server (3 tse and 1 file server)

no error on another server with the same configuration hardware and hyperv with 4 VM (1 exchange, sql 2, 1 dc)

[Vitaliy S.]

Can you please navigate to this host and then click on a Network Tab and choose "Current Object" as a chart option and select a "Network Errors" chart view? What does this view show you? Do you see a NIC which might the reason for these outbound errors?

thank you

Here is the tab in question:


The configuration of network cards on this Server


and the configuration of the teeming


the network card "connexion au reseau local" is the card port1 / Bay1, no error of traffic:



thanks

Thanks for the screenshots!

Do you possibly know what metrics does the HP utility use to calculate "Total Errors" parameter? The reason why I ask you about it is that with Veeam ONE we are relying on Windows performance metrics that can be found through Perf. monitor. Most likely HP is looking into something else for this metric.

Anyway it seems like these errors do no affect your VMs performance (based on your feedback), but I would still recommend to keep an eye on the outbound errors number. If this number will keep growing then you should take a closer look at your physical NICs/network configuration.

thank you

The last screenshot comes from HP GbE2c switch. what is strange is that my other hyperv connected to the same switch has no problem

[Vitaliy S.]

Actually there is nothing strange in this situation. Even though your hosts are from the same manufacturer, they have a different load on their network interfaces, which in turn might lead to situations like that.

Hi

I forgot to ask : what is the exact meaning of the * behind "Connexion au réseau local*" ?

[Vitaliy S.]

This is how your network should be displayed in "Network Connections" settings in the "Network and Sharing Center". Thanks!

[JMP-CAUX]

As you can see in the previous screen shots, in the "Network and Sharing Center" ther is
Connexion au réseau local
Connexion au réseau local 2
Connexion au réseau local 3
Connexion au réseau local 4
Connexion au réseau local 5
Connexion au réseau local 6
Connexion au réseau local 8
Lan Blade
Team Iscsi

but I don't know what is "Connexion au réseau local*" with a star (*) at the end.

[Vitaliy S.]

Oh, got it. One of the possible reasons for this extra character is a non-English Hyper-V server being used, looks like a localization UI glitch to me. Thanks for heads up!
