HAPTER 9: SIMPLE NETWORK MANAGEMENT PROTOCOL (SNMP)
Configuring SNMPv3 Contexts
SNMPv3 uses contexts to control access to a MIB object. A context is a
collection of management information that is accessed by an SNMP entity. A
single SNMP entity may be in more than one context. A single SNMP entity
may have access to many contexts.
Configuring SNMPv3 contexts involves:
1. Creating a context.
2. Setting a storage type for the context.
3. Setting the status for the context.
The following table describes the parameters that you set to configure
SNMPv3 Contexts:

NonVolatile:

delete the information but you can make modifications.

delete or modify the information.
