Am I not understand something?
Think about how this looks to the admin who's trying to monitor his/her systems. I'm particularly interested in one specific tuner that's been playing up recently, so I walk the AVInterfaceTable and the TunerTable, and find that it is the device with index 582 So I set up a script to regularly monitor the settings of the row with index 582. A few minutes later, your "container_load" routine kicks in to re-load the latest information, and chooses a completely new set of index values. Suddenly row 582 refers to a completely different bit of kit (or nothing at all), and the tuner that I'm actually trying to monitor now has index 319. That's clearly not very helpful for a sys admin. It's standard practise in SNMP for index values to remain stable - once you've assigned a particular index to a given row (and hence to a particular piece of hardware, or software, or whatever the MIB is monitoring), then that index should remain the same. It's usually acceptable to re-assign indexes if the whole system reboots (or the SNMP agent is killed and restarted). But not in normal operation. Does that make sense?
