SNMP Settings

Simple Network Management Protocol (SNMP) is an OSI Layer 7 (Application Layer) designed specifically for managing and
monitoring network devices. SNMP enables network management stations to read and modify the settings of gateways, routers,
switches, and other network devices. Use SNMP to configure system features for proper operation, monitor performance and
detect potential problems in the Switch, switch group or network.
Managed devices that support SNMP include software (referred to as an agent), which runs locally on the device. A defined set of
variables (managed objects) is maintained by the SNMP agent and used to manage the device. These objects are defined in a
Management Information Base (MIB), which provides a standard presentation of the information controlled by the on-board
SNMP agent. SNMP defines both the format of the MIB specifications and the protocol used to access this information over the
network.
The Switch supports the SNMP versions 1, 2c, and 3. The three versions of SNMP vary in the level of security provided between
the management station and the network device.
In SNMP v.1 and v.2, user authentication is accomplished using 'community strings', which function like passwords. The remote
user SNMP application and the Switch SNMP must use the same community string. SNMP packets from any station that has not
been authenticated are ignored (dropped).
The default community strings for the Switch used for SNMP v.1 and v.2 management access are:
•
public – Allows authorized management stations to retrieve MIB objects.
•
private – Allows authorized management stations to retrieve and modify MIB objects.
