9.6.4 SNMP Service
Nform has SNMP Service features for polling devices and testing Nform’s handling of traps, as listed
in Table 8.
• SNMP Agent Polling allows you to set up Nform to poll devices for their status at a specified
interval. By default, this feature is disabled (False) with a time interval of 1 minute.
When this feature is enabled, the icons in the Navigate tab indicate the status of each device
(see 7.2.2 - Informational Icons in the Navigation Tree): if any alarms are present, the status
is normal or the polled agent is not responding. (If there is no communication with a device, its
icon in the Navigate tab bears a large red X —when Nform displays this icon, verify that your
network cables are connected. If further action is required, consult the SNMP card user manual.)
• SNMP Comm Check allows you to verify that Nform is correctly receiving and processing traps.
By default, this feature is disabled (False), starting each day at 800 (8:00 a.m, military time).
When this is enabled, Nform sends an SNMP Comm Check Trap to the SNMP Trap Service.
To view or change any option:
• Log on as Administrator and click on the Configure tab.
• In the left side of the window, click on Domain Management.
• In the right side of the window, double-click on Local Domain, Services and Applications,
SNMP Service and finally Configuration to display the options.
• To change the setting for an option:
• Double-click on any option to open the Configuration window for that option. The example
above shows the SNMP Agent Polling option.
• Enter the appropriate change and click OK.
• Click on the File menu at the top of the window, and then click on Save.
(Or click the Save button on the toolbar.)
• A message window advises that the change will not take effect until after the service is
restarted. Click OK.
