SNMP sysName, sysLocation and sysContact definitely should persist over reboots. Either you are not saving your changes to non-volatile storage (e.g. Cisco write mem), or you have some pretty buggy code.

Hi, I apologize in advance if my question is not relevant to this mailing list. It's not about mrtg functionality but general SNMP protocol. I just want to know if there is a standard or specification that dictates SNMP objects persistence after a reboot. Specifically the sysName, sysLocation and sysContact. I've come across some devices that reset these to their default factory value after each reboot. Is this a common behavior? How many devices like that have you seen? What's your experience with sysName, etc.? Thank you Christian
