Sounds like a Hardware Compatibility List issue.
But I can only guess with the info provided.
run this froim the console of ESXi, if you have console access.
esxcfg-nics -s 100 -d full vmnic0
Thanks you guys its working now. Thanks a lot.
so we know now that the NIC or the switch port is not supporting 1000MBps
you might want to find out .. as 100MBps is too little these days .. specially if you are allowing anything other than management on that.
Thanks for your concern. Actually I am looking into it and need your kind suggestions
The server is Dell EMC 540 and installed Dell customized ESXI 6.7 U2. I did these changes on the ESXI after getting nic down error.
- I updated Dell firmware(CPLD, SAS, Network and BIOS) but did not work.
- Then I ran your command it started working fine.
I am copying data from old ESXI to new ESXI server through vswitch(1000Mbps). But after those changes now the data copying speed come down from 11 Mbps to 40 Kbps.
Can you help me to figure out this? I uploaded the screen shot of firmware(ESXi 6.7U2) updated.

ask you network admin to check the speed and duplex of the switch port where that physical nic is connected.
I have not checked the VMware HCL and I am assuming all the hardware is supported..
