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, mo nitor 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:
public - Allows authorized management stations to retrieve MIB
objects.
