PySNMP 3.x example applications

The following example scripts are based on various services provided by the PySNMP framework. The most of these tools try to behave as their UCD SNMP conterparts whenever possible.

When modelling your own apps after these scripts, see compatibility information section for more information on PySNMP API deviations and/or refer to package documentation.

• The snmpget.py script uses SNMP v.1/v.2c GET request to retrieve one or more SNMP objects (SNMP Object IDs and their associated values) from a SNMP agent.

• The snmpset.py script uses SNMP v.1/v.2c SET request to send one or more SNMP objects to a SNMP agent. User is expected to specify variable type from command line.

• The snmpwalk.py script uses SNMP v.1/v.2c GETNEXT request to iteratively retrieve one or more lexicographically larger SNMP objects from an SNMP agent.

• The snmpbulk.py script uses SNMP v.1/v.2c GET request to retrieve one or more SNMP objects from multiple SNMP agents at once.

  This tool is to demonstrate the use of pysnmp.bulkrole module which is designed to poll large number of SNMP agents at the same time (collecting accounting data from many routers at a specific moment, for example).

• The snmpbulkwalk.py script uses SNMP v.2c GETBULK request to retrieve a large number of SNMP objects (possibly SNMP table) from an SNMP agent.

• The asyncmgr.py script implements a simple Telnet like server that interacts with user via command line. User instructs server to poll arbitrary SNMP agent and report back to user when SNMP reply is received. Server may poll a number of SNMP agents in the same time as well as handle a number of Telnet sessions simultaneously.

  This script demonstrates the use of pysnmp.asynrole module designed to ease the binding of SNMP engine with a Python application built around asynchronous I/O engine (asyncore module).

• The snmpagent.py script acts as a SNMP agent (server). It waits for SNMP messages (of any type and protocol version) to come from a network and prints the details of received messages on stdout.

• The snmptrap.py script acts as a SNMP trap agent. It uses SNMP TRAP request (either of v.1 or v.2c) to send SNMP trap message to a SNMP manager.

  According to SNMP trap specification (RFC 1157, RFC 1905), SNMP manager is not expected to respond anything back to SNMP agent process upon trap message receiption.

• The snmptrapd.py script acts as a SNMP manager (trap server). It waits for SNMP trap messages (of either v.1 or v.2c) to come from a network and prints the details of received messages on stdout.

The above scripts are taken from PySNNP package. For more example tools, please, refer to examples/ directory of PySNMP distribution.
