ProSafe Network Management System

This is a single user version for managing small to medium sized networks. ProSafe NMS can be used on Windows 2000, 2003, NT, XP, ME, and 98 systems. All components run on a single system and support one user. The map database size is limited to 1,000 objects.

System Requirements

The following table lists the minimum recommended system requirements.
Table 1-3. Recommended system requirements
Parameter ProSafe NMS
CPU Pentium II 600 MHz Memory 128 MB Disk Free 500 MB Screen 800 x 600 Mouse Required Yes Console Operating System Win XP/2K/2K3/NT/ME/98

Device Access Modes

ProSafe NMS supports various device access modes including TCP only, ICMP (Ping), SNMP V1, SNMP V2c and SNMP V3. Each mode is briefly described below.
Introduction 1-3
September 2004 202-10058-01
Reference Manual for the ProSafe Network Management System NMS100

None (TCP Only)

Null access is used for polling TCP services only, where ICMP (Ping) and SNMP access is restricted by a firewall.

ICMP (Ping)

ICMP (Ping) mode is used for devices that do not support SNMP but can still be pinged to see if they are responding. This may include servers and workstations.

SNMP V1 and V2c

SNMP V1 and SNMP V2c are very similar SNMP agent protocols that are used by most currently deployed network devices. Any device that supports V2c will generally also support V1. ProSafe NMS uses automatic intelligence to switch from one mode to the other as needed. So in most cases select SNMP V1 as the device access mode for any SNMP device.
Since SNMP V1 and V2c are the most common and simplest SNMP protocols, this guide will only show you how to use these protocols.

SNMP V3

SNMP V3 is a secure SNMP agent protocol that supports authentication and privacy (encryption). The use of SNMP V3 is considered an advanced topic. As such, this guide does not describe V3 in any detail. For more information about using V3, please use the Help/Help Topics menu and search for Setting Device Access Modes in the Index.

Reference Manual for the ProSafe Network Management System NMS100
To remove one or more events, select the event and press the Delete key.
To acknowledge (remove current status of) an event, select the event and use the right-click Acknowledge menu.
To completely clear the event log, use the File/Clear Events menu.

View Window Area

The View Window Area is the main way to view the ProSafe NMS map and command results. This area uses the Multi-Document-Interface (MDI) specification to display multiple windows at the same time.
Use the Window/Cascade and Windows/T ile menus to rearrange the windows in the V iew W indow area in a way that makes them all visible.
Windows in this area can be in one of several states:
•A maximized window uses the entire area and hides any other windows behind it. If you close a maximized window , the next top-most window wi ll still be displayed in the maximized state. You need to be careful when using maximized windows because it is easy to lose track of how many windows you have opened and there is an uppe r limit. Use the Windows menu to see a list of windows. Use the Windows/Cascade menu to view all windows at the same time.
•An overlapped window does not take up the entire area. One window will be completely visible and other windows are partially hidden behind it. This is the most common situation for the View Window area because it lets you view maps, tables and graphs at the same time and quickly move between them.
•A minimized window is displayed as a small title bar with window Open and Close buttons. Windows are not typically minimized within the View Window area because, as with the maximized case, they can easily be lost behind other windows.

Working with the Map Database

The Map Selection Tree

Locate the Selection T ool on the right side of the console. If you do not see the Selection Tool, use the View/Selection Tool menu to show it. Select the first tab marked Map. The displayed Map Selection Tree shows all icon objects in the map. This includes subnets (which contain lower map levels), devices, and Goto icons. Networks and links are not shown in the Map Selection Tree.
Single-click the small box to the left of a subnet icon (folder icon) to open or close that sublevel in the selection tree.
Double-click on a subnet name (right of folder icon) to open that subnet level as a Map View window (see below).
Left-click on any object name to select that object. Use the Shift and Ctrl keys to select multiple objects.
Use the Delete key to remove selected objects.
After opening two subnet levels, select multiple device names and drag the mouse to move them from one subnet to another. Note that any attached links and networks are not moved, and links will be deleted during the move (you can re-add them manually later).
Right-click on a device icon (colored rectangle) or name to see the available right-click menus. Use these menus to edit the selected object properties, display tables, and run other custom menus.
Open a subnet tree and use the Insert/Map Object menus, or the Edit button bar to add icon objects to the subnet tree.
Each icon in the Map Selection Tree is colored according to the status of the represented object. Subnet icons (and the top level Root Subnet icon) show the highest priority color of all underlying objects.
