SNMP Security
SNMP does not include any formal type of security definition. However, security can be
accomplished using communities. A community is a string that is sent with every SNMP
request and is used to define a certain view of the MIB. By doing this, you can control
what parts of the MIB are accessed by an SNMP manager.

what parts of the MIB are accessed by an SNMP manager.
To restrict write access, there is an additional security step, involving defining a user
named snmp on the Q53 with root privileges. The password defined for this snmp user
will then be used as the community string which allows write access.

Managing with SNMP
SNMP (Simple Network Management Protocol) is a protocol for internetwork
management services. This protocol provides a means for computers (or agents) to be
managed remotely by managers. The level of management depends on the manager and
agent. The level of management ranges from providing information such as statistics to
providing full management capabilities.

MIB (Management Information Base) files are a description of managed objects
available in an agent. MIB files provide the data for the manager so they can remotely
manage the agent. A MIB file is simply a formal description of the way an agent can be
accessed using SNMP and what functions can be managed.
