[c-nsp] Nexus debug output

[Tim Stevenson]

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
