Odd behaviour in dvSwitch and Health Check

[andreaspa]

Hi guys,

I have run in to a strange issue with a dvSwitch in our lab. Three out of four hosts show errors on VLAN and MTU health.

If I look at on host having errors, this is what I see:

I've read some that it could be an issue with the host showing green, and not the others.

There was a misconfiguration in the switch for the host showing green - I had forgot to remove broadcast limits and storm constraints on the switch, and forgot to disable STP. All ports now have the same configuration, and I have rebooted the host with bad switchport config after correcting it, but still no luck.

Everything works - at least as far as I can tell, so it seems cosmetic..

Running latest builds of vCenter 6.7U1, vSphere ESXi 6.7U1 and NSX 6.4.3 (where NSX shows no warnings at all).

Any ideas?

Try disable and re-enabling health checks on the vDS.

Odd, that seems to have made everything green for now.. Thanks for the tip!
