Reboot Options
6.1. Ping-No-Answer Reboot
A Ping-No-Answer Reboot can be used to reboot one or more outlets when an attached
device does not respond to a Ping Command. In addition, the Ping-No-Answer Reboot
feature can also be configured to send an email, Syslog Message or SNMP Trap to
notify you whenever a Ping-No-Answer Reboot occurs. Please refer to Section 7.5 for
instructions on setting up email alarm notification for Ping-No-Answer reboots.
To set up a Ping-No-Answer Reboot, you must access command mode using a
password that permits Administrator level commands. In the Text Interface, the Ping-No-
Answer configuration menu is accessed via the Reboot Options menu (/RB). In the Web
Browser Interface, the Ping-No-Answer configuration menu is accessed via the Reboot
Options link. The Ping-No-Answer configuration menu can be used to Add, Modify,
View or Delete Ping-No-Answer Reboot functions.
Note: In order for the Ping-No-Answer Reboot feature to work properly, your
network and/or firewall, as well as the device at the target IP address must be
configured to allow ping commands.
6.1.1. Adding Ping-No-Answer Reboots
Up to 54 Ping-No-Answer Reboots can be defined. The Add Ping-No-Answer menu is
used to define the following parameters for each new Ping-No-Answer Reboot:
• IPAddressorDomainName: The IP address or Domain Name for the device
that you wish to Ping. When the device at this address fails to respond to the Ping
command, the VMR/NPS will reboot the selected outlets. (Default = undefined.)
Note: In order to use Domain Names, you must first define DNS parameters as
described in Section 5.9.5.
• PingInterval: Determines how often the Ping command will be sent to the
selected IP Address. The Ping Interval can be any whole number, from 1 to 3,600
seconds. (Default = 60 Seconds.)
Note: If the Ping Interval is set lower than 20 seconds, it is recommended to
define the "IP Address or Domain Name" parameter using an IP Address rather
than a Domain Name. This ensures more reliable results in the event that the
Domain Name Server is unavailable.
• IntervalAfterFailedPing: Determines how often the Ping command will be sent
after a previous Ping command receives no response. (Default = 10 Seconds.)
• PingDelayAfterPNAAction: Determines how long the VMR/NPS will wait to
send additional Ping commands, after a Ping-No-Answer Reboot has been initiated.
Typically, this option is used to allow time for a device to fully "wake up" after a
Ping-No-Answer Reboot before attempting to Ping the device again.
(Default = 15 Minutes.)
• ConsecutiveFailures: Determines how many consecutive failures of the Ping
command must be detected in order to initiate a Ping-No-Answer Reboot. For
example, if this value is set to "3", then after three consecutive Ping failures, a
Ping-No-Answer Reboot will be performed. (Default = 5.)
