Sup 720 NVRAM lithium battery voltage display command?
Cisco appears to use a lithium battery for holding NVRAM (as opposed to some type of EEPROM or flash technology which they used in generations past). My observations are that the battery can go bad and cause undesirable things like booting into ROMMON after a power cycle and/or fully corrupted NVRAM.
Although I have only observed this on cat 6500, I anticipate that the cat 4500, and Nexus series can encounter similar problems. Not sure about smaller switches, haven't taken a hammer and screwdriver to them yet.
Is there a way to display the voltage of the lithium battery on supervisor engines? Oh and if so how
