PC-8024f & Vmware 6.7 cant ping subnet
Hi,
Have a strange issue where I cant ping inside the 8024F from another subnet. I have two Dell R820 connected to a PC-8024F and the 8024f is connected to a CISCO 3945-e router. The problem I'm having is (once I start the esxi host or run a SoftPerfect NetworK scan on the ip range 192.168.2.0/24) I lose the ability to ping anything on the 8024F subnet after a few mins. Everything else is working fine (VM in the cluster are fine, they are responding to incomming traffic), I just lose the ability to ping the anything in subnet. This is causing me issues in VCENTER when I try to open up a VM console, I get an error cant connect. But if I run a SoftPerfect NetworK scan on the subnet 192.168.2.0/24 I can connect for a few mins without any problems. I'm at a loss on what the problem is. Please let me know what you think, TY.

Hello @johnlongo1959,
What is the firmware on 8024F?
If you disconnect the 8024F from the CISCO router, what is the connection result within the 8024F subnet? If without starting the ESXi host or the SoftPerfect Network scan, does the other clients on the 8024F network able to ping/reach other?

I can ping the VM's that are running in that subnet (192.168.2.0/24) the same subnet that the ESXI Host management ip is running in. The management ip is the only ip I get a timeout when I try to ping it.

Hello @johnlongo1959,
Were you able to reset the switch? What is the current configuration? Is there any configuration that could prevent this ping?

How is the port to the server configured? It is acting like there is a loop being created that it is causing the connection drop.

Not sure how to fix this, I can ping a VM but the management ip I can't see attached.

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.
