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-1526 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:
