Hello all, I have a bit of a weird problem and I'm not having much luck with the search option.
Let me describe how I got to the point I am at with this:
We have about 29 VM's running on our vmware esxi server, all of them are more or less for internal testing purposes. All of these vm's use 2 network ports on our vmware device, but are seperated using virtual switches and vlans. One of the network port connects to a dumb switch and another connects to a cisco switch with trunking on the interface.
I created a brand new vm and a new vswitch to test bridging mode in a product we are using. I modified an older vm to connect to this new vm switch, and then the new device to connect to this new switch, our public vlan, and our internal network. The idea was that the bridge would allow the older vm to continiue to talk to the public vlan as normal, but the bridged device would work transparently in the middle.
Once I finished this configuration and started the bridge device, the network of our entire building ceased to function, including my connection to the vmware server. Once I realized that this had happened, I walked over to the physical piece of hardware and unplugged it entirely from the network. The rest of the building then went back to its happy network-purring self.
Unforunately, I have usb passthrough turned on, and was unable to connect to the terminal on the esxi server. Instead, I simply pushed the power button and let the server shut down.
Once it came back up, the nic that was previously attached to the trunking port of the cisco (vmnic0) had/has stopped working. Once I managed to get into it on the other interface, I was able to issue a "esxconfig-nic -l" which shows the device as down.
On the back of the server, I can see the vmnic0 has a yellow light and a green light. The functioning vmnic1 has two green lights. I switched network cables on the two interfaces once to see if anything would change, it did not.
Does anyone have any ideas?
Thanks,
