Dell PowerEdge R430 Neetwork Adapter only 100Mbits
Dell PowerEdge R430
I have a Dell PowerEdge that I use for an ESXI Host 6.7
The R430 has 4 internal network adapters 100/1000
On my ESXI Host Looking at the Physical Adapters and NIC0 show 100mbit/s All others show 1 GBit/s
I also have a dual network PCI card and both those nics at 1 GBit/s
I noticed this the other day when looking on my network speed on my vCenter cluster and this ESXI host one of 4 hosts in the cluster. Backup jobs with VM's on this host are slightly slower \\
This NIC is used as vmnic0 on vswitch0 which is VMnetwork on my VMware
I tried on VMware to change the setting to 1000 currently it is set as dynamic
When I use iDrac to the Server I see the same information for nic0 set as 100 mbits
Is it possible I have a bad nic?
How to make it 1000 ?
Maybe I could use one of the open nics then
Any suggestions
Thank you
Tom

did you build the server using the Dell OEM media? it has all the drivers it needs included for their servers
1. ESXi version - is it OEM from DELL ?
2. Drivers - are you using the drivers from DELL.
3. Firmware - has the firmware been updated for the server, especially the network controllers.
and then we come on to....
4. Network cables.
5. Network ports.
Swap and Change 4 & 5 above with known working ports with are 1GBe.
Do not use FIXED speed and duplex, use Auto Negotiate.
It's a common issue!

Thanks for responding
The ESXI version is 6.7 U3 and yes from Dell not using OEM version
All my network adapters are set to Auto negotiate
I will have to migrate all VM's off to make this change to another NIC
This NIC is the VMnetwork NIC and I have it setup with NIC1 on the Management Network
But I have the VCSA appliance on this host and running in HA mode it went down the other day when I changed the network adapter from Auto negotiate to 1000 So I think it is best to migrate all the VMS to my other Hosts while make the change. Or is there a better way?
Thank you

a bit confused by that so you downloaded and installed from Dell ?

Good, that's how they are supposed to bet set.

not sure what all this is about....?????

do not force to 1000, this is WRONG!
Hence why it went wonky....
BUT do you only have a single NIC connected to the vSwitch <---- no redundancy???

I have two nics connected to the vSwitch.
I was thinking of this
One Enable to spare NIC from the ESXI Host Console currently VMNIC6 is down
If I enable it then add it to vSwitch0 Once it is added to vswitch one then I can take VMNIC0 and disable it on the ESXI Host console and it will show Down on the Physical adapters
Thoughts?

Ok Andrew after Diner with start that process
is nic0 your idrac port?

no nico is connected to my Cisco switch
the idrac port has a separate cable plugged in

Thanks for all the input.
I played around with moving the cable to another port on my Cisco switch still was 100 mbits.
Then I enabled my spare nic and the same results it came up as 100 mbits.
The problem was the ethernet cable I changed the cable and now back to 1gbits.
Thank you

If I was you I'd cut that cable in half and then dispose of it.
Yes, we've seen a few cables that don't do 1GBe, we've thrown them out! often they don't have all the wires!
yes those have only 2 pairs connected 1GBe requires all 4 pairs.
