  • * *SNMP has become the most popular network management protocol for its simplicity and scalability. *Simple Network Management Protocol (SNMP) is commonly used within NMS(Network Monitoring System) *Tools like Cacti and OP Manager use SNMP for querying devices. *SNMP is the de-facto standard for Network Monitoring. *SNMP is integrated into most of devices like routers, switches, servers and workstations.
  • * *SNMPv1 :Simple Network Management Protocol (RFC1213)has MIB2 *SNMPv2c: (RFC1907) includes security, confidentiality *SNMPv3 :(RFC2275)addition of cryptographic security ensures confidentiality, integrity and authentication *It is Internet-standard protocol for managing devices on IP networks *community Strings :Read Only and Read write
  • * *An SNMP-managed network includes management stations and network devices *Agent software which runs on managed devices *Network management system (NMS) software which runs on the manager *MIB (Management Information Base), can monitor the state of hardware and software, and the running state of the system.
  • * SNMP sends and receives information on port UDP 161 and 162
  • * The collection of objects is referred to as management information bases (MIB)This MIB tree gives the OId(Object Id)
  • *
  • *
  • * *Net-SNMP is a suite of applications used to implement *SNMPv1, SNMPv2c and SNMPv3 using both IPv4 and IPv6 *A library for developing new SNMP applications, with both C and perl APIs *Information from snmp enabled device is collected by commands like • snmpget • snmpgetnext • snmpwalk • snmpset • snmptrap
  • * 1. Snmpget: request to query for information on a network entity Eg: snmpget -v1 -c public localhost system.sysUpTime Or snmpget –v1 –c private Here system.sysUpTime is named OId of which be can get by 2. snmptranslate and vice-versa. Similarly 3. snmpwalk: is an SNMP application that uses SNMP GETNEXT requests to query a network entity for a tree of information. 4. snmpset: is used to set the information from users terminal
