DIS-200G Series Industrial Gigabit Ethernet Smart Managed Switch The Switch incorporates a flexible SNMP management for the switching environment. SNMP management can be customized to suit the needs of the networks and the preferences of the network administrator. Use the SNMP V3 menus to select the SNMP version used for specific tasks. The Switch supports the Simple Network Management Protocol (SNMP) versions 1, 2c, and 3. The administrator can specify the SNMP version used to monitor and control the Switch. The three versions of SNMP vary in the level of security provided between the management station and the network device. SNMP settings are configured using the menus located on the SNMP V3 folder of the Web manager. Workstations on the network that are allowed SNMP privileged access to the Switch can be restricted with the Management Station IP Address menu.

To view the following window, click Management > SNMP > SNMP Global Settings, as shown below: Figure 5-3 SNMP Global Settings window The fields that can be configured for SNMP Global Settings are described below: Parameter SNMP Global State Description Select this option to enable or disable the SNMP feature. The fields that can be configured for Trap Settings are described below: Parameter Trap Global State SNMP Authentication Trap Port Link Up Port Link Down Description Select this option to enable or disable the sending of all or specific SNMP notifications. Tick this option to control the sending of SNMP authentication failure notifications. An authenticationFailuretrap is generated when the device receives an SNMP message that is not properly authenticated. The authentication method depends on the version of SNMP being used. For SNMPv1 or SNMPv2c, authentication failure occurs if packets are formed with an incorrect community string Tick this option to control the sending of port link up notifications. A linkup trap is generated when the device recognizes that one of the communication links has come up. Tick this option to control the sending of port link down notifications. A linkDown trap is generated when the device recognizes a failure in one of the communication links. 35

DIS-200G Series Industrial Gigabit Ethernet Smart Managed Switch
35
The Switch incorporates a flexible SNMP management for the switching environment. SNMP
management can be customized to suit the needs of the networks and the preferences of the network
administrator. Use the SNMP V3 menus to select the SNMP version used for specific tasks.
The Switch supports the Simple Network Management Protocol (SNMP) versions 1, 2c, and 3. The
administrator can specify the SNMP version used to monitor and control the Switch. The three versions of
SNMP vary in the level of security provided between the management station and the network device.
SNMP settings are configured using the menus located on the SNMP V3 folder of the Web manager.
Workstations on the network that are allowed SNMP privileged access to the Switch can be restricted
with the Management Station IP Address menu.
