I've spent time creating a good config on an ASA 5540. I did a copy-run-start then reloaded it. It comes up with a blank config. I copied start to flash:start.cfg then boot config flash:start.cfg, then another copy run start. Then another copy start flash:start.cfg. I haven't tested whether the config comes up after a reload it as it is Friday and I don't want to touch it after recreating that unbacked up config.
How do I assure the ASA will keep my running config when I wr or copy run start then reload it or if it recycles after a power spike? (UPS are old)
