Esxi 6.7 Loosing the ability to ping management ip after a few mins

[johnlongo]

Hello,

I have an issue with two Esxi 6.7 hosts where I lose the ability to ping the management ip. 

When I do a ping for management ip 192.168.2.21 or 192.168.2.22 it times out. But I can ping a VM in the same subnet 192.168.2.10 and I don't understand why. I can reestablish the ability to ping the ip's (for a few mins) by using a tool called netscan to scan the subnet 192.168.2.0/24 but after a few mins the pings start timing out again.

Any help resolving this issue is greatly appreciated.

Thread reported so moderators know it should be moved to the area for ESXi.

Hello.
Try to ping between ESXi
1. Make a SSH connection to the ESXi (you must enable SSH on the ESXi)
2. Login with user root and the respective password
3. run ping between ESXi hosts, attached example
# ping 182.168.196.1 -c 100
I assume that the 2 ESXi hosts are connected to the same external switch.

f there are no outages the problem is on another side of the network, not on the ESXi.

If there are outages you need to check the driver and firmware of your ethernet cards. Indicate the version (Build) of the ESXi you are using and the make and model of your ethernet cards.

I think I fixed the issue I switch span tree mode to mts and for the past hour or so I haven't seen a timeout.  so I'm going to close this thread. thank you all for the help.
