Chapter 3: DSView Server 57
• Trap Destinations - Displays the DSView Server Trap Destinations window, which enables
you to specify up to four trap destinations. The DSView Server polls DSR switches and CPS
appliances to determine if they are responding. If a DSR switch or CPS appliance does not
respond, the DSView Server sends an SNMP Loss Of Communication (LCM) trap to the
external SNMP manager. When the DSView Server detects that the DSR switch or CPS appli-
ance is once again communicating, a Regained Communication (RCM) trap is sent from the
DSView Server.
When a response change occurs during communication between the DSView Server and a
DSR switch or CPS appliance, the DSView software writes the event to the audit log and sends
an SNMP trap to the trap destinations you specify.
An SNMP trap is an automatically-generated alert containing either information or error
explanations. The following two traps are generated by the DSView software:
a. LCM (loss of communication) with appliance
b. RCM (regain of communication) with appliance
NOTE: Trap destinations may also be specified by clicking on a DSR switch or CPS appliance and modifying the
SNMP appliance settings. See Modifying DSR switch or CPS appliance SNMP settings on page 168 for
more information.
• DSView Client Sessions - Displays the DSView Server Client Session Properties window,
which enables you to specify DSView Client session settings for inactivity time-out, Single
Sign-On (SSO) for the DSView session or restrictions to use specific IP addresses to start
DSView sessions.
• Email - Displays the DSView Server Email Server Properties window, which enables you to
change the IP address of the SMTP (Simple Mail Transfer Protocol) server that is used by the
DSView software to send email notifications.
• Unit Status Polling - Displays the DSView Server Unit Status Polling Properties window,
which enables you to turn on or off unit status polling for the DSView Server and specify the
delay between polling cycles and the number of DSR switches and CPS appliances that will be
concurrently polled.
• Spoke Servers - Displays the Spoke Servers window, which contains the Spoke DSView
Servers configured for your DSView system and enables you to manage them.
