[f-nsp] debugging restarts

[Frankie John-Lewis]

Hi Joseph,

In the last few weeks I have experienced similar scenarios to yourself.

One on RX1600 and XMR4000. 

Both cases were solved by switching to the standby management card.

In both cases were a relevant window was available the MC was brought
back online an caused instability on the network. 


Both of these cards have been replaced and everything seems to be fine.

In my previous experience, check to see if you have any issues with the
switch fabrics and Line Cards, can you get a maintenance window?

Also check to see if the you get an network anomalies before the FI
restarts.

What version of firmware are you running buddy?

Good luck and shout if you need help.

Hi Jeroen,

We have an external syslog server, but nothing shows up except the Warm 
restart.  I need to take a put a console cable and hope something shows 
up screen before crash.

Thanks

Joe
