View source for SNMP

SNMP means Simple Network Management Protocol.  It is a protocol that allows the querying of data from a network device such as a switch or router.  It also allows traps which are the opposite of a query in that network devices contact a single host that collects these for further analysis or generating an alarm for the network operators.

One use that's common is [http://oss.oetiker.ch/mrtg/ MRTG] to generate a nice graph of something such as bits per second through an interface or aggregate.
