A single word	`cat`	Topics that contain the word "cat". You will also find its grammatical variations, such as "cats".
A phrase. You can specify that the search results contain a specific phrase.	`"cat food"` (quotation marks)	Topics that contain the literal phrase "cat food" and all its grammatical variations. Without the quotation marks, the query is equivalent to specifying an OR operator, which finds topics with one of the individual words instead of the phrase.

NNMi Calculations for State and Status

By default, NNMi automatically enables ICMP polling of each Node’s management address, including those Nodes residing in a NAT environment (Configuration > Monitoring > Monitoring Configuration, the Default Settings tab, ICMP Fault Monitoring section’s Enable Management Address Polling setting). If you have a NAT environment, it is highly recommended that you do not disable this setting.

Note In the Inventory > SNMP Agent view, select an SNMP Agent and use the Actions > Monitoring Settings command. The displayed information indicates whether NNMi has this management address polling enabled.

When Management Address Polling is enabled, the Agent ICMP State field appears in the following locations:

Node form
SNMP Agent form
SNMP Agent table views

The following table shows how NNMi behavior changes based on ICMP Fault Monitoring settings. The first row in the table shows the NNMi default settings.

Monitoring Configuration Settings and the Resulting State Poller Behavior
ICMP Fault Monitoring Settings		Resulting NNMi Behavior
Enable Management Address Polling	Enable IP Address Fault Polling	Agent ICMP State	IP Address State
Enabled	Disabled	Polled	Not Polled
Enabled	Enabled	Polled	Polled
Disabled	Disabled	Not Polled	Not Polled
Disabled	Enabled	Not Polled	Polled

When Management Address Polling is enabled, NNMi considers both the management address’s ICMP response and the SNMP Agent’s response when calculating conclusions and generating incidents.

The following table shows the SNMP Agent Status calculations determined by the combined ICMP and SNMP responses.

Determining SNMP Agent Status

Responding	Responding	Normal
Responding	Not Responding	Minor
Not Responding	Responding	Critical
Not Responding	Not Responding	Critical
