This object specifies how the row for a given community entry is stored, such as volatile, nonVolatile, or permanent. Admins care because a permanent row need not accept write access to its columns, which affects whether a community's settings can be modified or deleted via SNMP versus only through local configuration. For example, a community defined in the device's startup config might show as nonVolatile so it survives a reboot but can still be edited by an authorized manager.
