Description:

SNMP (Simple Network Management Protocol) is a protocol used for network
management (hence the name). The NET-SNMP project includes various SNMP
tools; an extensible agent, an SNMP library, tools for requesting or
setting information from SNMP agents, tools for generating and handling
SNMP traps, a version of the netstat command which uses SNMP, and a
Tk/Perl mib browser. This package contains the snmpd and snmptrapd
daemons, documentation, etc.

Install the ucd-snmp package if you need network management tools.
You will probably also want to install the ucd-snmp-utils package, which
contains NET-SNMP utilities.
