Ping-No-Answer Fallback Switching
• ConsecutiveFailures: Determines how many consecutive failures of the Ping
command must be detected in order to initiate Ping-No-Answer fallback switching.
For example, if this value is set to "3", then after three consecutive Ping failures, the
specified Circuit Module(s) will then be switched. (Default = 3.)
• Toggle: Enables/Disables the Ping-No-Answer Fallback function for the specified
IP address. When enabled, the AFS-16 will switch the selected circuit(s) or Circuit
Group(s) when the target device fails to respond to a ping command. When
disabled, the AFS-16 will not switch the specified circuit(s) when a ping failure is
detected, but will continue to notify you via Email, Syslog Message and/or SNMP
Trap, providing that parameters for these functions have been defined as described
in Section 5.9 and the Ping-No-Answer Answer alarm has been enabled as
described in Section 7.3. (Default = No.)

• CircuitAccess: Determines which Circuit Modules will be switched when the IP
address for this Ping-No-Answer Profile does not respond. Note that in the Text
Interface, Circuit Access is defined via a separate submenu; in the Web Browser
Interface, Circuit Access is defined via a drop down menu, which is accessed by
clicking on the "plus" sign in the "Configure Circuit Access" field.
(Default = undefined.)
• CircuitGroupAccess: Determines which Circuit Group(s) this Ping-No-Answer
Profile will be applied to. Note that in the Text Interface, Circuit Group Access
is defined via a separate submenu; in the Web Browser Interface, Circuit Group
Access is defined via a drop down menu, which is accessed by clicking on the
"plus" sign. (Default = undefined.)
• PNAAction: Determines how the AFS-16 will react when the IP address fails to
respond. The PNA Action parameter allows you to select either a Continuous
action or a Single Action as described below: (Default = Continuous.)
• Continuous: (Default) The AFS-16 will continuously restart the PNA Check cycle
at the specified circuit(s) or group(s) until the IP address responds.
• Single: The AFS will switch the specified circuit(s) or group(s) only once when
the IP Address fails to respond to a ping command.
• PingTest: (Text Interface Only) Sends a test Ping command to the IP Address or
domain name that has been defined for this Ping-No-Answer Profile.
