While in other SNMP communication, the manager actively requests information from the agent, these are PDUs that are sent from the agent to the manager without being explicitly requested. SNMP Traps enable an agent to notify the management station of significant events by way of an unsolicited SNMP message.
Features user-level security, allowing an administrator to prevent access to certain parts of the product on a per-user or per-role basis. IPv6 Supports monitoring IPv6 hosts and/or devices, receiving IPv6 data, and running on an IPv6-enabled server. Supports communication using IPv6 to the SNMP agent via an IPv6 address.
A management information base (MIB) is a database used for managing the entities in a communication network.Most often associated with the Simple Network Management Protocol (SNMP), the term is also used more generically in contexts such as in OSI/ISO Network management model.
In computing, the Structure of Management Information (SMI), an adapted subset of ASN.1, is a technical language used in definitions of Simple Network Management Protocol (SNMP) and its extensions to define sets ("modules") of related managed objects in a Management Information Base (MIB).
[citation needed] These network elements use a management agent (MA) to perform the network management functions requested by the network management stations. The Simple Network Management Protocol (SNMP) is used to communicate management information between the network management stations and the agents in the network elements. NMS is ...
Network management is the process of administering and managing computer networks. Services provided by this discipline include fault analysis, performance management, provisioning of networks and maintaining quality of service .
CMIP was a key part of the Telecommunications Management Network, and enabled cross-organizational as well as cross-vendor network management. On the Internet, however, most TCP/IP devices support SNMP and not CMIP. This is because of the complexity and resource requirements of CMIP agents and management systems.
In short, RMON is designed for "flow-based" monitoring, while SNMP is often used for "device-based" management. RMON is similar to other flow-based monitoring technologies such as NetFlow and SFlow because the data collected deals mainly with traffic patterns rather than the status of individual devices.
