So if I want to upgrade past 4.6.2, I have to go and change all my SNMP tags? Who’s brilliant idea was this?
No, just re-enable the SNMP functions. Jump straight to 4.7.1 to skip the initial knee-jerk reaction settings which made you update your passwords regardless of what you had in there.
you will be forced to use a community string that is at least 8 characters long though, so be prepared to update if your strings are not 8 characters or longer.
