Network > SNMP
Short for Simple Network Management Protocol, SNMP is a set of protocols
for managing network devices. SNMP works by sending messages, called
protocol data units (PDUs), to different parts of a network. SNMP-compliant
devices (
agents ), store data about themselves in Management Information
Bases (MIBs) and return this data to the SNMP requesters.
The KVM uses the Net-SNMP package (http://www.net-snmp.org/). The Net-
SNMP package contains various tools relating to the Simple Network
Management Protocol including an extensible agent, an SNMP library, tools
to request or set information from SNMP agents, tools to generate and handle
SNMP traps, a version of the unix 'netstat' command using SNMP and a
Tk/Perl mib browser.
SNMP is configured with community names, OID and user names. The KVM
supports SNMP v1, v2 and v3. The two versions require different
configurations. SNMP v1/v2 requires community, source, object ID and the
type of community (read-write, read-only). V3 requires user name.
Important! Check the SNMP configuration before gathering information
about KVM by SNMP. There are different types of attacks an unauthorized user
can implement to retrieve sensitive information contained in the MIB. By
default, the SNMP configuration in KVM cannot permit the public community
to read SNMP information
