not in use, it is disabled by moving it into a default vlan. When you
swap in an experiment, the interfaces assigned are moved into newly
created vlans. We do this so that additional interfaces not in use do
not appear as active, possibly confusing the OS or your application
code.
The wires table tells snmpit how to "address" the actual interfaces on
the switches. It needs to match what the switch thinks. In the output
you sent, it appears that the switch has the interfaces on card 1
instead of card 0.
Sorry, I am a little confused. Each of those three nodes has one interface for control, and two interfaces for experiment. I thought two interfaces should be recognized by the experiment switch, so as indicated in the 'wires' table field 'port2'.
Then, I rollbacked the ports mapping of 'port2' to the original
'port2', but the same error happened again in another experiment.
So, we had said "card2" not "port2" ... which did you change?
First, what does the field 'card2' mean? I changed it to 'card2=1' as advised. Then, I found there were some mis-match of 'port2' on experiment switch because I checked the physical ports on the switch and I thought they must be matched on the 'wires' table field 'port2'. After these two database operation, I started an experiment through website, and got that "Port not found, skipping" error message. Maybe my understanding was wrong?

One thing at a time ...
Sorry about this, I will put another email on this topic.
