4. Type the appropriate values in the fields, and then click OK to save the settings for this SNMP

To remove previously created SNMP targets from the SNMP Targets selection list, select one (or more) 
SNMP target entries from the list and then click Remove.

Click Global SNMP Settings to configure SNMP settings that will be used by Device Crawlers for all 
SNMP target communications. The Global SNMP Settings window opens. This window contains the 
following fields: 

Delete SNMP Sensors if 
Not Found on Crawled 
Device

When checked, automatically removes previously defined 
SNMP-based sensors on a target when, after a successful scan, the 
sensors are found to no longer be present (no longer defined, 
unavailable, and so forth). If the sensors are not deleted, they will 
be displayed with sensor reading values of “N/A” or “null.”

Send Offline alert if 
SNMP agent becomes 
unavailable

Check this check box if the monitored device has an SNMP agent 
and you want Device Crawlers to generate an alert if the device’s 
SNMP agent on this target is unavailable. If the SNMP agent is 
unavailable, the Device Crawlers Online sensor status for this 
device will report an Online status value of “No,” enabling you to 
configure thresholds and generate alert notifications in response 
to this status change.
Note: If the target device does not have an SNMP agent, be sure 
to leave this check box unchecked. If this check box is checked 
and the target does not have an SNMP agent the Online sensor 
status will always report a “No” value, regardless of whether the 
device is online or not.

Send Offline alert if 
ICMP ping times out

Check this check box if you want Device Crawlers to generate an 
alert if ICMP Pings directed at the target device time out. If this 
time out occurs, the Device Crawlers Online sensor status for this 
device will report an Online status value of “No,” enabling you to 
configure thresholds and generate alert notifications in response 
to this status change.

Scan Interval

Use this control to specify the number of minutes that must pass 
between Device Crawlers target queries.

Maximum Route Hops

Use this control to specify the maximum number of hops that will 
be recorded and saved by Device Crawlers route tracing support.   

Include Route Trace in 
Alerts check box

Check this check box to enable Device Crawlers route tracing 
support. If this check box is not checked, route tracing is disabled 
and alert notifications will not include route tracing data.
