Alarm Configuration
7.3. The Ping-No-Answer Alarm
The Ping-No-Answer Alarm is intended to provide notification when one of the IP
addresses defined via the Ping-No-Answer function (as described in Section 6) fails
to respond to a Ping command. When one of the user-defined IP addresses fails
to answer a Ping command, the AFS-16 can provide notification via Email, Syslog
Message or SNMP Trap.

7.3.1. Defining Ping-No-Answer IP Addresses
In order for the Ping-No-Answer Alarm to function, you must first define at least one
Ping-No-Answer profile as described in Section 6. To define a Ping-No-Answer profile
and associated IP address, proceed as described in Section 6.

7.3.2. Configuring the Ping-No-Answer Alarm
To configure the Ping-No-Answer Alarm, you must access the AFS-16 command mode
using a password that permits Administrator Level commands. The Ping-No-Answer
alarm configuration menu offers the following parameters:
• TriggerEnable: Enables/Disables the trigger for this alarm. When Disabled, this
alarm will be suppressed. (Default = On.)
Note:Tocancelanalarmwithoutcorrectingtheconditionthatcausedthe
alarm,simplytoggletheTriggerEnableparametertoOffandthenbackOn
again.
• ResendDelay: Determines how long the AFS-16 will wait to resend an email
message generated by this alarm, when the initial attempt to send the notification
was unsuccessful. (Default = 60 Minutes.)
• NotifyUponClear: When this item is enabled, the AFS-16 will send additional
notification when the situation that caused the alarm has been corrected. For
example, when Notify Upon Clear is enabled, the AFS-16 will send initial notification
when it detects that a Ping command has failed, and then send a second
notification when it determines that the IP address is again responding to the Ping
command. (Default = On.)
