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 SNMPv1 and SNMPv2c, 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 SNMPv1 and SNMPv2c management access are:

• public – Allows authorized management stations to retrieve MIB objects.

• private – Allows authorized management stations to retrieve and modify MIB objects.
