VM unable to ping another VM in different ESX host with the same VM Network Label
Hi All,
I'm having weird issue here with one of my VM, the SCCM Vm in the below scenario cannot even ping the domain controller (DC02-VM) hosted in different ESXi blade host while it can ping the DC01-VM in the same blade host.
in the vSwitch there are two pNIC working as the uplink simultaneously. All of the servers only have one vNIC.
ESXi01 contains the following VM:
SCCM01-VM
DC01-VM
ESXi02 contains the following VM:
DC02-VM
after migrating it into another host as follows, the SCCM server can ping to the DC02-VM which wasn't ping-able, but now it cannot ping DC01-VM:
ESXi01 contains the following VM:
DC01-VM
ESXi02 contains the following VM:
DC02-VM
SCCM01-VM
the strange thing is that between DC01-VM and DC02-VM they can both ping-ing to each other.
what to look for and idea for trouble shoot please ?
I noticed that the VM network label are all the same VLAN and IP address class.

are the VLANs tagged correctly on the vSphere vSwitch and physical switch.

Hm.. if that is the case then it is the Networking team issue not us the server team ?
could you upload screenshots of your vSwitches
what physical switches are you using.

I believe that there are two CISCO switches for redundancy reason.
the Cisco CDP is turned off based on PCI requirement (for security purpose in production facility).
