What Is HiVision?

HiVision is an SNMP or Simple Network Management Protocol software offered by Hirschmann Electronics to help facilitate Management, monitoring and configuration of SNMP enabled network devices.

What Is SNMP?

SNMP or Simple Network Management Protocol is a standard language that allows Network Manager applications to interact with Network Agent applications.

What can be managed by SNMP software ?

Hubs Switches Routers UPS’s Device Servers Computers Printers Or any other device that would

be SNMP enabled.

What is Network Management software ?

Network Management software can:o Poll Network Agents for

real-time network status.o Set values in Network

Agents.o Provides a graphical user

interface to network administrators to show network alarms, network architecture, etc.

What is a Network Agent?

A Network Agent is an embedded application running in a manageable network device that accumulates real-time information about the performance of the network device it runs on.

The data table in a Network agent is called a Management Information Base (MIB).

What is a MIB?

Two types of MIB’s: Public MIB’s include information that

would be common to a wide range of network devices.

Private MIB’s include information that would generally only be found in the specific device that contains the private MIB.

What is a Public MIB?

Public MIB data is governed by a set of standards set by IETF

(Internet Engineering Task Force)

Examples of public MIB information include:o Port Link Status.o Traffic In-Flow per port.o Traffic Out-Flow per port.o Errors per port

What is a Private MIB?

Examples of private MIB information include:o In a UPS

• Line or Battery Power• Battery Strength

o In an industrial Switch• Power Supply Health• Redundancy Status

o In a Device Server• Serial Port Statistics

With Traps: agent immediately indicates events with alarm messages reducing polling to a minimum

With Gauges: agent itself monitorsindividually configured thresholds no polling data, just traps

Polling vs. Traps

Polling vs. Traps

SNMP traps allow network devices to report on exception instead of being polled regularly, reducing network traffic.

Traps reduce the traffic load on the network by only sending traffic when alarm conditions occur, rather than continuous “polling” by the network management software.

Multiple network management programs can be on a manageable network device’s Trap list, allowing IT and plant personnel to both monitor the same network.

After installation, click the HiVision icon on your desktop and select configuration from the tool bar, then preferences.

Select “new”

Makes sure "Scan Ranges" is highlighted in the left hand column…

Enter the IP addressrange and subnet maskto be scanned

Click apply

Make sure the “active”button is checked then click OK!

You will then see the scan range you justdefined. Click OK

You then return to themain screen and select"Edit" then "Rescan Range"

Then select from the list of scan ranges defined to scanthe network—Click OK

As you can see from the fields listed, there is some pretty significant information listed about your network and the devices on it

On the first page, we have the current view of "Active Devices" on the network as well as; IP Address, Product description, location of device, software version, device status, etc…

By clicking on/selecting the device to view, you are able to "dive down" into the device and get some more prevalent information.

We are able to determine certain port characteristics simply by observing the graphical LED's shown on the devices GUI.

An empty port means nothing is attached, a port with a hollow circle means only one device is attached and a port with a solid circle indicates multiple devices attached to the port…Probably indicating another networking device is attached

By double clicking a specific port, we can view the characteristics of that port.

This screen gives specific information of the corresponding port; port on or off, auto negotiation, speed, duplex operation, etc…

By selecting device description, we are able to individualize each device on the topology. System name and location as well as contact information are configured into the switch as well as other criteria…

By double clicking the "Agent Dialog" icon, we are presented with the configuration and performance criteria of the device.

This is where we as the management station are able to configure certain aspects and characteristics of the device as a whole: Multicast Filtering (GMRP, IGMP) Port Mirroring VLAN's Prioritization etc…

The Performance tab under the Agent dialog window, gives the user a visualization of the port statistics for a number of criteria…

By selecting the statistical graph within the Performance tab under the Agent dialog window, we are able to display important characteristics of the port such as Load, Collisions, packet types and sizes.

The Security tab under the Agent dialog window, gives the user a visualization of the Learned Address Table of the switch as well as the ability to configure traps and configure port security.

In order to configure a trap, we would first select the configuration tab under traps. We would then be shown the criteria configuration page. Here would set the conditions that we wanted to receive traps on such as; Cold Start, Link Down, Link Up, Redundancy, etc…

We would then select the destination tab in order to determine where the traps would be sent…

By clicking on one of the lines, we are presented with the destination editor where the IP address of the destination station would be identified…

The Events tab under the Agent dialog window, gives the user a visualization of traps received as well as specific status changes to the device.

The Events tab off the Main window, gives the user a visualization of traps received as well as specific status changes for ALL the devices collectively

HiVision also offers a "Multi-Device" port manager. The Port Manager gives the option to "Globally" configure all ports on all devices at the same time.

HiVision also offers a "Multi-Device" configuration manager. The Configuration Manager gives the option to "Globally" save any or all configuration files on all devices at the same time.

HiVision and SNMP management offer many advantages in Network wide visualization and configuration that many other less sophisticated methods can provide.
