Re: [Testbed-admins] Emulab Rebuild Problems

Yes -- that is exactly the test I've been running -- switchmac from a 
boss shell (from the boss console, in fact, su'd to user 'elabman') 
after the newnode MFS has booted and is sitting at a login prompt.

The MAC address does show up in the switchmac output, is on the correct 
switch and port, and shows the "ctrl" tag at the end. This is the only 
instance of that MAC address in the switchmac output (unlike before, 
when "leakage" was causing 2 occurrences of that MAC). And yet the 
control port address isn't identified via the web page at all. Does 
switchmac have any debug/diagnostic options? I was planning on diving 
into the switchmac script tomorrow (Wednesday)...
