[c-nsp] Nexus debug output

[Bob Sinclair]

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
