Hello guys,
Let me briefly apologize in advance as I am not a vmware engineer and don't understand the intricacies of vmware.
I stumbled across this issue trying to troubleshoot why our Windows deployment server was crawling during the initial TFTP download of files. As I was trying to rule things out I came across this within ESXI itself.
On our ESXI host I have been noticing events stating -
Network connectivity restored on virtual switch "xxxx", protgroups: "xxxx", "xxxxxxx". Physical NIC vmnic0 is up.
However, there are no logs stating that the physical NIC went down.
This happens fairly frequently, at least every hour. It also seems to happen when VM's are rebooted as well as PXE'ing.
When I look in vobd.log I see -
[netCorrelator] 1234567us: [vob.net.pg.uplink.transition.up] Uplink:vmnic0 is up. Affected portgroup: XXXX 1 uplinks up
[netCorrelator] 1234566us: [esx.clear.net.connectivity.restored] Network connectivity restored on virtual switch "xxxx",portgroups: "xxxx" "xxxxxxx". Physical NIC vmnic0 is up.
This is happening roughly every 10~ minutes.
Again, I see no correlating "Physical NIC went down" logs.
EDIT: a few details I forgot to enter -
ESXi 6.7 update 1
Driver bnxtnet
(I will add as I think of things or things are asked)
Thanks in advanced. Hopefully this is a no duh no brainer issue.
Nate
