SNMP Terminology (continued)
Definition
A type of security algorithm that is performed on each SNMP
packet. There are three levels: noauth, auth, and priv. The noauth
level authenticates a packet by a string match of the username.
The auth level authenticates a packet by using either the HMAC
MD5 or SHA algorithms. The priv level authenticates a packet by
using either the HMAC MD5 or SHA algorithms and encrypts the
packet using the CBC-DES (DES-56) algorithm.
The security strategy that is used by the SNMP agent. Currently,
Cisco IOS software supports three security models: SNMPv1,
SNMPv2c, and SNMPv3.
A network management protocol that provides a method to
monitor and control network devices and to manage
configurations, statistics collection, performance, and security.
Second version of SNMP. This protocol supports centralized and
distributed network management strategies and includes
improvements in the structure of management information (SMI),
protocol operations, management architecture, and security.
A copy of SNMP that can reside on the local or remote device.
Unlike SNMPv1 and SNMPv2c, in SNMPv3 the terms SNMP
Agents and SNMP Managers are no longer used. These concepts
have been combined and are called an SNMP entity. An SNMP
entity is made up of an SNMP engine and SNMP applications.
A collection of SNMP users that belong to a common SNMP list
that defines an access policy, in which object identification
numbers (OIDs) are both read-accessible and write-accessible.
The users belonging to a particular SNMP group inherit all of
these attributes that are defined by the group.
A person for which an SNMP management operation is
performed. The user is the person on a remote SNMP engine who
receives the inform messages.
A mapping between the SNMP objects and the access rights that
are available for those objects. An object can have different access
rights in each view. The access rights indicate whether the object
is accessible by either a community string or a user.
A view name (not to exceed 64 characters) for each group; the
view name defines the list of object identifiers (OIDs) that can be
created or modified by the users of the group.
