For security reasons, only limited access to objects of the SNMPCommunityMIB is
possible with the SNMPv1/v2c Read Community String. With the SNMPv1/v2c
Read/Write Community String, you have full access to the SNMPCommunityMIB.

If the function is enabled, an SNMP engine ID is generated that can be migrated.
You can transfer configured SNMPv3 users to a different device.
If you enable this function and load the configuration of the device on another
device, configured SNMPv3 users are retained.
If the function is disabled, a device-specific SNMP Engine ID is generated. To
generate the ID, the agent MAC address of the device is used. You cannot transfer
this SNMP user configuration to other devices.
If you load the configuration of the device on another device, all configured
SNMPv3 users are deleted.
