NOS - is running config persistent?


hi,
very specifically - should config survive "sudden death" such as power cut.

example:
nos 7.2.0a1 - two switches in logical chassis(since it's the only way) - power loss to both switches at the same time.

Will such net stack be identical (assuming no HW issues) after power recovery to what it was before power loss?

many thanks, L.

They usually come up with no issues. I would say its a 90/10 rule, 90% of the time they come up ok. If something happens and the fabric becomes segmented all you need to do is default the backup switch and when it reboots it will pull its config from the Principal switch and the fabric will form.
