We had a 6509 hybrid switch reboot recently and we ran in to problems restoring the config. We eventually restored the config but the issue of boot variables and switch.cfg files , etc. is still ringing in our heads. .We were told that the switch creates a switch.cfg file by default and also, by default, points the CONFIG_FILE variable to boot off of this switch.cfg file. Fine...We then took a look at the bootflash and/or slot0: files on our hybrid switches and found that some of them do not have a switch.cfg or any type of .cfg file. So, when we are making our daily non-default changes...where are they going? And if one of these switches reboots..where does it go to get a .cfg file? I understand that configs are saved to NVRAM so shouldn't I see some type of .cfg file listed in flash?
