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.

Enabling ICMP Polling of the Management Address in a NAT Environment

By default, NNMi automatically enables ICMP management address polling for all nodes, including those nodes residing in a NAT environment. If you have a NAT environment, it is highly recommended that you do not disable this setting.

To enable ICMP management address polling (if it is disabled), do the following:

From the workspace navigation panel, select the Configuration workspace, expand the Monitoring folder, select Monitoring Configuration, and locate the Default Settings tab.
Enable ICMP Management Address Polling. See Set Default Monitoring in the NNMi help.

View the information NNMi displays after performing Actions->Monitoring Settings for SNMP Agents. The displayed information indicates whether NNMi has the management address polling enabled.

When ICMP Management Address Polling is enabled, NNMi changes as follows:

The Agent ICMP State field appears in the following forms:
- Node form
- SNMP Agent form
- SNMP Agent table views
NNMi changes the display location of the management address ICMP state. NNMi also changes the way it determines the SNMP agent status.

The following table shows the Agent ICMP and IP Address state polling actions that NNMi takes for the ICMP Management Address Polling and ICMP Fault Polling settings.

ICMP Configurations and Resulting State Polling
ICMP Management Address Polling	ICMP 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

The following table shows changes to the SNMP Agent Status determined by APA for the SNMP agent and ICMP responses.

Determining SNMP Agent Status
SNMP Agent Response	Management Address ICMP Response	SNMP Agent Status
Responding	Responding	Normal
Responding	Not Responding	Minor
Not Responding	Responding	Critical
Not Responding	Not Responding	Critical

With ICMP polling of the management address enabled, APA now considers the management address ICMP response and the SNMP agent response when generating conclusions and generating incidents.
