[f-nsp] Flapping stack

Thu Aug 13 12:42:55 EDT 2015

Thank you

I ended up ringing support and I think I have hit a bug.

The flapping is constant - I'm upgrading the code and restarting later

Thanks !

Hi Nick,

You could just try to de-configure the flapping port as a stack-link, and then proceed to disable it quickly afterwards. That chunk of config should be right at the top of your "show running-config".

Best regards,

Good afternoon chaps,

I have a flapping stack cable - but I can't seem to disable one of the cables - anyone knowhow to do this?

Any Ideas?

Also why does the sh stack connection - change what is connected everytime I run it?

CPU to CPU packets are fine between 2 units.

I am so confused - I need to get this healthy remotely if possible.

Thanks!
