2 VM's not pinging out of 4

[virtualdive]

Hi

I have a HP Proliant DL385 G2 server that has ESX 3.5 U5 running and is hosting 4 VM on it. The issue is 2 out of those four VM's are pinging perfect and rest two are not.

All these 4 VM's have exactly same settings, not sure where is it going wrong.

Please can someone suggest?

Check the port group you have the VMNics connected too. Ensure they are on the same port group on the smae vswitch - also ensure they have the correct IP's. If they are using DHCP ensure they are getting an IP.

Secondly, are you trying to ping them from a physical machine?

Take a look at the physical switch port. This looks like you are connected to a managed switch with port security enabled.

For Cisco you should set "switchport mode access" and "spanning-tree portfast".

Some Cisco of the switches come with a "macro description cisco-desktop" which limits the port to a minimum number of 2 MAC addresses allowed on the port.

Thanks Guys,

I tried everything you suggested and finally I deleted the virtual NIC from the 2 VM's that were not pinging and re-added them. It worked fine! Wierd!

I guess it had something to do with MAC address that could have been corrupted on the VM adaptor which might be dropping packets on the 2 VM's.

It is really strange though!

Thanks again Andre' and Chad,
