Thanks Leigh, I am a partner of Mohammed at LSU. We are working together on our first testbed. Here is some information I can complement for your reference. >Can you ping cisco2 from boss?

We have one Control and one Experiment (aka Data) switch with same cisco 24 gi0/1-24 ports. OPS is connected to Control switch and Boss is connected to both. The attachment is our physical topology design. Our design is very simple because of a test environment. Currently, we don't use the default vlan1 but created Vlan 2 for both Control and Experiment switch. For Vlan 2, gi0/1-20 ports are statically assigned. And we use port gi0/20 for connecting Control and Experiment switch. Thus, vlan 2 is for everything in control and experiment scenario. There are also 4 ports un-assigned. The community string in Control switch is 'vlan1', and in Experiment switch is 'vlan2'. But don't be confused, we just want to diff them from our cisco1 and cisco2 accordingly. Other are mentioned in Mohammed's previous email. One thing I want to say is that the cisco2 seems to be customized for something which I am not sure, because it is borrowed and everything works fine before this problem. Please help us if there is something wrong in our design or any configuration. Thanks a lot. Best Regards, Cheng Cui 578-5445 . 231 Johnston Hall .

What vlans have you created on your switches and what is in them. Before anyone on this list can help, you need to provide some good details about your setup. Here in Utah the staff is completely swamped, so it might be a long time before anyone can offer much help. You might have to dig in on your own if no one on the list can help.
