User guide

If an automatically discovered DSR switch that has been set as a managed appliance is deleted,
the DSView 3 software attempts to automatically discover the DSR switch again and add it to
the Unmanaged Appliances list. The automatic discovery process continues unless the DSR
switch is turned off or has the DSView 3 server address removed.
Managed Appliance SNMP Settings
This procedure is valid for supported KVM switches and serial console appliances. It may also
be valid for appliances supported by a plug-in; see the appropriate documentation.
The SNMP protocol is used to communicate management information between network
management applications and DSView 3 software managed appliances using TCP/IP and IPX
protocols. Other external SNMP managers (such as Tivoli
®
and HP OpenView) may
communicate with your managed appliances by accessing MIB-II (Management Information
Base) and the public portion of the enterprise MIB. MIB-II is a standard MIB that many SNMP
target devices support. The managed appliances will send their traps directly to the external
SNMP manager in addition to sending it to the server.
The following settings appear under SNMP in the side navigation bar:
• System - Enables/disables SNMP. When you enable SNMP, the managed appliance will
log SNMP received messages over UDP (User Datagram Protocol) port 161. UDP port 162
is used to listen for incoming traps.
• Managers - Stations that can manage the managed appliance.
• Community - Communities to which the traps belong.
• Destinations - Stations that can receive SNMP traps.
• Traps - Available traps and enabled/disabled traps.
The traps must be also configured on each managed appliance using the Command Line
Interface (CLI). The address of the server running the DSView 3 software must be configured as
a trap recipient, the proper community must be set and each desired trap must be enabled.
SNMP traps are logged in the event log file. See Displaying the Event Log on page 392. SNMP
traps may also be configured from a system task. See Task: Configure SNMP trap settings on a
managed appliance on page 368.
To change SNMP settings for a managed appliance:
1. In a Units View window containing appliances (see Accessing Units View windows on
page 118), click on the appliance name.
