[c-nsp] What to collect when router reload

[Yasser Aly]

Rodney,
 
 As a side note to this, how does core dump helps in analyzing hardware problems.
 
Moreover, is it wise to make the core dump destination over a WAN link, or the router won't have enough time to ftp the core dump contents before crashing?
 
Regards,
Yasser

You want the 'sh stack' after it reloads.

And why are you running an interim release on 12.2T?
You should only run an interim as a last resort to get
a bug fix while waiting for the next release to go on CCO
and upgrade then.

Interims are not well tested so running them is a risk.

I don't know but check bootflash and see if the RPM
saves a crashinfo file also.

Get that information to TAC.
