SNMP Setting
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 DES-2110 supports the SNMP versions 1. In SNMP v.1, 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
management access are:
public - Allows authorized management stations to retrieve MIB
objects.
private - Allows authorized management stations to retrieve and
modify MIB objects.
