I found some commands in this Cisco document (ID 44800) for reading BRIDGE-MIB objects on a per-VLAN basis. I have also found information in the furoms and elsewhere about SNMPv3 access to such information.
My understanding is that, one must configure each and every VLAN in a context to allow an SNMPv3 user access to them.
Is that a correct and current understanding?
If so, it seems to be difficult to scale accross a few hundreds of devices. What is the best practice for allowing an SNMPv3 user access to all things on all devices?
