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:

1 2 ... 45 46 47 48 49 50 51 52 53 54 55 ... 94 95
