<p>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.

<p>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.

- <p>It is also possible to write your own Net if process. The default
- Net if process is implemented in the module <c>snmpm_net_if</c> and
