SetRequest — request to change the value of a variable from the manager to the agent. GetNextRequest — request to find variables from the manager to the agent. Response — reply from the agent to the manager through the return of variables. Trap — simultaneous message from the agent to the manager. InformRequest — simultaneous messages between managers. SNMPv1, which is the network management protocol being used by the Internet.
It contains improvements in performance, confidentiality, security, and communications between managers. Its party-based security system is very complex, though, and has to be revised in order to be able to use it with the SNMPv1. SNMPv3, which has added cryptographic security and new concepts, terminology, remote configuration enhancements, and textual conventions.
Its new security features are:. It provides confidentiality through the encryption of packets to block intruders from the outside. It assures message integrity by protecting packets with a protection mechanism. It ensures that the message is from a reliable source.
SNMP version 3 was different due to the addition of new features of texts, concepts and new terminologies. But SNMPV2 is a more widely used protocol version but some people now consider version 2 as obsolete. Version 2 was introduced with inform features that acknowledged the receipt of messages by the manager while version 3 authenticates each message and ensures privacy.
Skip to content SNMP or Simple Network Management Protocol is a protocol for internet standards that helps in the collection and organization of the information related to the managed devices present on the IP networks. Simple Network Management Protocol version 2 is the standard protocol for the internet to collect and organize information regarding the managed devices present on the IP networks, it was an improved version of the earlier launched versions with some improvements.
Simple Network Management Protocol version 3 is also an internet standard protocol for the same purpose, however, it has improved cryptographic security, remote configuration enhancements, textual conventions, etc.
