What is the point of SNMP?

Although the original purpose of the Simple Network Management Protocol (SNMP) was to let network administrators remotely manage an Internet system, the design of SNMP lets network administrators manage applications and systems. SNMP provides the following capabilities: Hides the underlying system network.

What is PDU SNMP?

Each SNMP message contains a protocol data unit (PDU). Sent by the SNMP manager to retrieve the next MIB variable that is specified in the PDU. You can have multiple requests in the PDU. This PDU is primarily used by the SNMP manager to walk through the SNMP agent MIB.

Who uses NETCONF?

The NETCONF protocol has been implemented in network devices like routers and switches by some major equipment vendors. NNMi uses NETCONF to gather information about the device during discovery or rediscovery. NNMi doesn’t use NETCONF to modify device configurations or to watch status or performance metrics.

How is NETCONF better than SNMP?

One of the big advantages of NETCONF over SNMP is how the protocol works when manipulating a group of semantically related configuration data. Whereas SNMP modifies the value of a single parameter at a time, NETCONF modifies all or selected parameters on a single primitive operation.

What is the best SNMP tool for monitoring devices?

Community is a free SNMP-based monitoring tool, best suited to home or evaluation use. The Pro and Enterprise editions are priced on a yearly subscription basis. Every edition features an auto-discovery utility to identify all the devices on your network and then report on their status.

How do I control SNMP on a network?

To control SNMP, you must have a network management system, or NMS, which can be installed on any computer on the network. The NMS navigates and manages the system, compiling, storing, and requesting status information; the SNMP software agents respond to its requests.

What are the different versions of SNMP?

RFC 1157: This is a refined version of the first SNMP definition, commonly referred to as SNMPv1. Due to its longevity—it’s been around since 1988—this is the version with the most implementations. RFC 1901: This second version features improved error-handling functionalities.

What is SNMP and ICMP used for?

SNMP can be used for polling (a monitoring station queries a network device) and notifications (a device sends an SNMP TRAP or INFORM to a monitoring station). ICMP (ping): The Internet Control Message Protocol (ICMP) is the protocol that the popular ping and traceroute/tracert commands use.
