Hi Bob,
Try using the "debug-filter" options - eg, if you're debugging ospf in vrf foo:
debug-filter ip ospf vrf foo
debug ip ospf adj
The debug-filters are really pretty powerful, it helps you narrow
down the debugs to just what you're looking for. Filters are
available for most L3 protocols & infrastructure.
Hope that helps,
Tim

Thanks Tim! That was it. Huge help!
I can also now debug activity in a non-default VDC, but only for activity
on default vrf interfaces. That seems like a real limitation, but I cannot
find any vrf keywords on debug commands. I also tried changing
routing-context to the non-default vrf, but that did not help. Any way to
debug activity in the non-default vrfs? For example, debug ip ospf events?
Thanks!

Hi Bob,
What are you pinging? I assume it's something out the mgmt0 interface. In
this case, debug ip packet detail will not generate any output - many debugs
are applicable to the inband interface only (as in this case).
One alternative if you want to capture mgmt0 traffic is to use the
ethanalyzer, eg something like:
ethan local int mgmt capture-filter "icmp" limit-captured-frames 20 detail >
bootflash:foo
etc.
Or, if you're just trying to see how the debug logfile works, ping something
connected to something other than mgmt0.
Hope that helps,
Tim
