Leigh,
ok, we had some problems with SNMP on the switches that are fixed and helps, but after running the switchmac tool the output shows all the ctrl interfaces on both the ctrl and expt switches, but the expt switch has all the nodes ctrl interfaces as the port of the crossover cable between the switches. This leads to some questions: can we just connect boss directly to expt instead of using a crossover to ctrl? should expt uplink port be in vlan1? or a different vlan? We think all the ports on expt are in vlan1 by default, thus spilling over to ctrl, different vlans would seam to fix this? does this sound like anything you've seen? also when we run the "search switch ports for selected nodes" button on the web interface it doesn't find any ports on the expt switch, and it defaults the ctrl switch entries to the first one found with was the spillage results from the uplink port (referenced before.)
Sorry I can't send the direct output, it is on a secure network with out any direct output connection and we can't use a USB stick or floppy or anything to copy files from the testbed.
Thanks for the help.

We are trying to add about 90 experimental nodes into our new emulab
setup. We're using the "New Testbed Node" web interface to add
these nodes. We set each node to the proper NodeID, Identifier,
Type, IP, and set the switch type, card, and port for each
interface. The make_dhpcd does not add the new nodes properly
because the query which returns the proper IP for each MAC returns
empty. Our problem seems to be that the interfaces database
registers ALL interfaces as 'expt' type. Because of this, probably,
no IPs are being added to interfaces also. Can you suggest what we
could do to remedy this? We can change them by hand, but with six
interfaces on 90 nodes, this is a bit of a headache.
I agree. This is intended to be mostly automated ... but the DB state
has to be correct. Lets try and figure this out for just one node
though. :-)
With one of your nodes booted into the newnode MFS, run this:
boss> /usr/testbed/libexec/switchmac
You might have to filter out the lines that do not apply to the one
node you picked to work with, which will be a real pain if all the
other nodes are still in the newnode MFS. Might want to power them
down.

ps: the web interface calls out to switchmac, so once we get that
output correct, the web interface should start saying the right
things.
