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:
