4.3.5.Ping Commands
The Cortex can monitor the state of IP networks and IP-connected device through the use of 64 configurable Ping
commands on the CORTEX 360 and 32 Ping commands on the CORTEX 320. The input identifier (ID) of these commands
is 1N, 1N2, 1N3…etc.
For any ping request that is configured and that does NOT receive a proper ping reply, the corresponding Identifier will
become active (high). This input can then be used to generate alarms, log events, or take action such as pulsing a relay to
power-cycle a network device. The commands can also be useful to automatically diagnose problems in multi-branch
networks.
Please see Section 4.3.1 for details about the generic

Below is the Actions configuration menu screen of the Ping Command inputs.
1 – ID
ID of the selected input. Select from the drop-down menu.
2 – I/O DESCRIPTION RETRIEVAL
Click to retrieve and display the current normal or active description. Normally hidden to minimize data transfer on
low speed or high fee data connections.
3 – ACTION TYPE
Selects the action type that will happen when an out-of-limit condition occurs. 3 types are available: Major alarm,
Minor alarm, and Command (CMD). On CMD, no alarm will be triggered. Use this Action when you want to take
actions without triggering any alarms.
4 – QUALIFIER
Qualifying element (operand) which can be any input, output, flag, timer, SNMP GET, Logic Gate, etc. Essentially
any ID in the Cortex can be used to mute or unmute the input to prevent it from taking any action. When the Qualifier
is active, the input will be monitored and be able to generate alarms. When the qualifier is non-active (or normal),
the input will be muted and it will not be able to generate an alarm. To invert the Qualifier’s level, simply put a ! in
front of its ID. For example, use !1D01 to invert it. Leave the Qualifier field blank for a “don’t care” condition.
5 – PING ADDRESS
IP address that will be Pinged and monitored.
6 – CONTROLLED OUTPUT
Outputs to be controlled (on/off) based on the state of this input. The two output types allowed are relays (both
physical and virtual) and SNMP SETs. For the relays, adding a P suffix will Pulse the relay (ex: 1R01P), L will Latch
it and R will Release it.
