(Newbie Question) - Networking Setup

To All,

I just recently installed ESX 3.0 on a HP DL300G5 system. I currently have two network interfaces installed and hooked up on the system. One is currently dedicated to running the SC, the other I am configuring on its own seperate vSwitch to run VM's on.

My issue resides with the vSwitch for the VM's. I had my network guys verify that the physical interface is on the correct VLAN, however none of my VM's can talk out of there interfaces (on the same VLAN). I can see from within the "Network Adapters" menu in the VIC that the interface is up and shows the proper Network range. Anything that I am missing?

TIA,

-Jason

Do you have a VLAN tag configure in your vSwitch/Port group, if so remove it. You should only use these when using 802.1Q VLAN tagging to support multiple VLAN's on a single physical switch port.

Issue these commands from the service console and paste the results:

esxcfg-nics -l

esxcfg-vswitch -l

esxcfg-vswif -l

route -n

Also - make sure that the Virtual Machine subnet you are using is configured to route via any upstream switches beyond the one that you are physically cabled into (i.e. at the AGG level).

Good luck.

Guys,

Thanks for the response. After further investigation (and some prodding on my part) it turns out that the physical switch port on the switch was not set to trunk, it was still configured as an access port. Once we switched that all is now working.

Thanks again,

-Jason
