Simple Network Management Protocol (SNMP) is a communication
protocol designed specifically for managing devices on a network.
Equipment commonly managed with SNMP. SNMP is typically used to
configure these devices for proper operation in a network environment,
as well as to monitor them to evaluate performance or detect potential
problems.
Managed devices supporting SNMP contain software, which runs locally
on the device and is referred to as an agent. A defined set of variables,
known as managed objects, is maintained by the SNMP agent and used
to manage the device. These objects are defined in a Management
Information Base (MIB) that provides a standard presentation of the
information controlled by the agent. SNMP defines both the format of
the MIB specifications and the protocol used to access this information
over the network.
The switch includes an onboard agent that supports SNMP versions 1,
2c, and 3. This agent continuously monitors the status of the switch
hardware, as well as the traffic passing through its ports. A network
management station can access this information using software such as
LantechView. Access to the onboard agent from clients using SNMP v1
and v2c is controlled by community strings. To communicate with the
switch, the management station must first submit a valid community
string for authentication.
Access to the switch using from clients using SNMPv3 provides
additional security features that cover message integrity,
authentication, and encryption; as well as controlling user access to
specific areas of the MIB tree. The SNMPv3 security structure consists
of security models, with each model having it's own security levels.
There are three security models defined, SNMPv1, SNMPv2c, and
SNMPv3. Users are assigned to ―groups‖ that are defined by a security
model and specified security levels.
Basically, it is passive except issuing the trap information. The switch
supports a switch to turn on or off the SNMP agent. If you set the field
SNMP ―Enable‖, SNMP agent will be started up. All supported MIB OIDs,
including RMON MIB, can be accessed via SNMP manager. If the field
SNMP is set ―Disable‖, SNMP agent will be de-activated, the related
Community Name, Trap Host IP Address, Trap and all MIB counters will
be ignored.

The predefined default groups and view can be deleted from
the system. You can then define customized groups and views for the
SNMP clients that require access.
