Figure 13.1: The Purpose of Manager Net if

The Network Interface (Net if) process delivers SNMP PDUs to the manager server, and receives SNMP PDUs from the manager server. The most common behaviour of a Net if process is that is receives request PDU from the manager server, encodes the PDU into bytes and transmits the bytes onto the network to an agent. When the reply from the agent is received by the Net if process, which it decodes into an SNMP PDU, which it sends to the manager server.

However, that simple behaviour can be modified in numerous ways. For example, the Net if process can apply some kind of encrypting/decrypting scheme on the bytes.

The snmp application provides two different modules, snmpm_net_if (the default) and snmpm_net_if_mt, both uses UDP as the transport protocol i.e the transport domains transportDomainUdpI
