Simple Network Management Protocol (SNMP)

SNMP is an application layer protocol which uses UDP port number 161/162.SNMP is used to monitor network, detect network faults and sometimes even used to configure remote devices. There are 3 components of SNMP:

  • SNMP Manager – It is a centralised system used to monitor network.It is also known as Network Management Station (NMS)
  • SNMP agent – It is a software management software module installed on a managed device. Managed devices can be network devices like PC, router, switches, servers etc.
  • Management Information Base – MIB consists of information of resources that are to be managed. These information is organised hierarchically. It consists of objects instances which are essentially variables.[1]
