Vmware instances not able to see network

Hello Experts,

I have 4 vmware instances that need to see the network. I have a virtual switch and both can they all can see each other as they are connected to the virtual switch. However, they can not see the network. In talking to my network people, we can see that there is a connection from the server to the switch port, but no activity. I know that we would be able to see the mac addresses of the instances and that would be a teltale sign of connectivity. (Outside of confirming the actual duplex speed within vmware options-physical adapters.)

Is there a way for me to verify the configuration of the switch?

Thanks..

Can you please elaborate on your description of the sentance, "I have a virtual switch and both can they all can see each other as they are connected to the virtual switch."

I'm not sure what you're trying to communicate?

Did you add at least one physical nic to the virtual switch?

Sorry...

I have 4 vmware instances. they can see each other, but can't see the main network. I need them to see the main network.

They are connected to a virtual switch, however, it seems as if that virtual switch is somehow not bound to the physical adapter.

I know that there is a network connection between the server and network because I've checked on the network switch itself and I've also check the physical adapter settings within vmware.

Cybersean,

I thought I did. What would I do or where would I go to verify.

In ESX, you would highlight the host, click configuration, then networking, then properties (above the virtual switch), Network Adapters Tab
Then click Add to add the nic

Which vmware product are you using?  workstation?  virtual server? esx?

Cybersean,

Using ESX 2.5.4. We've had to fight and scratch to get our client to order 3.5 which just happened yesterday. It probably won't be here for a month, but in the meantime, I need to configure a test environment and I need to get this up and running soon.

Thanks again...

I understand you're using ESX 2.5.X

Page 189-190 of http://www.vmware.com/pdf/esx25_admin.pdf explains it better than I can remember/explain it.

Yes, the directions I provided earlier were for 3.5.  Bogdan's link about walks you through the steps on 2.5.  That should get you up and running.

Is it already assigned to that vswitch?  Or something else?  You may have to delete/recreate the vswitch.
