You can use the SNMP Viewer tool to view and monitor SNMP objects for a device. There are three ways that you can select the device for which you want to see SNMP information:
From the Tools menu, select SNMP Viewer, then enter the information described below.
In the SNMP Viewer, from the File menu, select New, then enter the information described below.
Right-click a device in the map, then select SNMP View from the pop-up menu. The SNMP Viewer shows the interfaces for that device.
Host Name. Enter the host name or IP address of a device.
Community. This is the password used for SNMP read permission for this device. (Note: You can set the Read Community for all maps and all devices by using the Replace SNMP Community feature.)
Timeout. Enter the timeout. A value of 500 or greater is treated as milliseconds; less than 500 as seconds. If a device does not respond to the SNMP request within this time, the request times out.
