Viewing SNMP Group Information

The SNMP Group window; disabling and enabling authentication failure traps

The Simple Network Management Protocol (SNMP) facilitates communication
between a management application, like NetSight Element Manager, and a
network device, through the use of Protocol Data Units (PDUs). A network
manager requests data by issuing a Get-Request or Get-Next Request PDU, or
writes a new value into the device’s MIB by issuing a Set-Request PDU. The agent
responds to Gets by issuing a Get-Response PDU or sends asynchronous
notification of unusual events to the manager by issuing a Trap PDU.
To open the SNMP Group window from the System Group window:
1. Click the Other Groups button. The Other Groups drop-down menu displays.
2. Click SNMP Group. The SNMP Group window, Figure13-1, opens.
NOTE
This window displays only if your device’s firmware supports MIB-II for Network
Management of TCP/IP-based internets.
NOTE
In order for your device to issue any traps—and in order for your management
workstation to receive those traps—your SNMP device’s trap table must have been
properly configured via Local Management or the Remote Administration Tools
application; refer to the hardware documentation or the Remote Administration Tools
User’s Guide for more information. In addition, refer to the Alarm and Event
Handling User’s Guide for more information on the alarm logging facility.
