Looks like we have an issue with one of the cisco switches. I will look.

I am still trying to figure out what is wrong with our cisco switch
management after the Emulab upgrade. This only affects the pc3000 nodes
as they are the only ones connected to cisco switches. If you can work
on the d710 or d430 nodes you will not see this.

This should be fixed now. A subtle change it the behavior of the net-snmp
package was causing our code to fail.

It's working now on these pc3000 nodes. Thanks for the fix!
