How Can TOP Server help?
What is SNMP?



SNMP – Simple Network Management Protocol
An Ethernet protocol
Unlike regular drivers, we aren’t getting PLC or
control system data via SNMP
What is SNMP?


SNMP standardizes access to managed device
health and configuration information
All major IT devices that are “managed” support
the SNMP Protocol






Routers
Network Switches & Hubs
Firewalls
UPS power backups
Generators
Even some control devices!
Why SNMP?





Automation depends on critical IT
infrastructure
IT infrastructure uptime directly impacts
operational profitability
Putting network/infrastructure “health”
information in front of the right users
empowers them to act sooner when
problems occur
Less downtime = More Profitability
A message that fits for any industry!
Examples of Information
Provided by SNMP







UPS battery capacity remaining
UPS battery failure warnings
UPS power/battery status (on utility
power or battery)
Switch port traffic volume
Switch port status (connected/not
connected)
Alerts of system problems
And many more
Terminology Introduction

OID = Object Identifier


MIB file = Management Information Base


A big sequence of numbers that represents the “address” for a parameter
A text file that lists the OIDs and their uses for each status parameter
available in the device
SNMP Trap = an event that a managed network device generates based
on configured conditions

Example: UPS goes off utility power and onto battery power

Ping = a simple command you type at the DOS prompt followed by the
IP address to see if a device is responding on the network. Useful to
see if non-managed devices are responding and working

SNMP Community Name – like a password

SNMP Agent = an SNMP Slave Device

SNMP Manager – in this case TOP Server, but in the IT world, this
would be a Network Management System like HP Openview or Tivoli.
Now before the IT Manager Asks..

TOP Server SNMP Suite





Is not a replacement for their IT tools like HP
Openview or Tivoli, rather a complement to
these systems.
Is typically used in a read only configuration
Can limit what an operator or control engineer
sees to a “need to know” list of items
Should be used to have the controls group
provide more helpful information when they
report a problem to IT
If used properly should actually make the IT
team’s job easier
What Tools are Needed?

TOP Server SNMP Suite

Three levels of licensing






1-15 device license, US$895
16-50 device license, US$1795
Unlimited device license, US$2495
License for a single computer
Annual support and free upgrades: US$175
– US$495 depending on license level
Also part of the vertical industry IT &
Infrastructure Suite

TOP Server
SNMP Suite Overview



Includes SNMP and Ping Drivers
Ping Driver is available for non-managed
ethernet devices and provides
online/offline status of these devices
SNMP v1 and v2c supported (SNMP v3 not
presently supported)


Supports standard TOP Server protocol
diagnostics
Includes a number of standard device
MIBs as part of the install.

Considerations

Use primarily for monitoring of managed network
systems
Polled points (SNMP GET) and unsolicited events
(TRAPs).
Data is organized in hierarchies.

Configuring the SNMP Driver

So let’s see how to configure the
driver – we’ll highlight these
differences as we get to them in

Give your device a name that
is useful to you.
Give the correct IP address of the
SNMP-enabled device you wish to
monitor.

You will need to set your timing. In most
cases the defaults are acceptable.

SNMP Version

3 official SNMP versions


1 draft SNMP Version


2c – known as the “real” Version 2 in practical use
TOP Server supports



1, 2, and 3
Version 1 and 2c.
Does not currently support version 3 but most V3 devices still
support 1 and 2c
SNMPv3 provides three important services that are
incompatible with previous versions, which is why we do not
yet support V3

Configuration – SNMP Communications
SNMP Port and Protocol
The Port number and
Protocol are used when
communicating to the
remote device. Ports may
range from 1 to 65535. The
default Port is 161. UDP
and TCP protocols are
available. UDP is the
default Protocol.
If you change these at the
server, you must configure
this on your device as well.
Configuration – SNMP Communications
SNMP Community



The next screen allows you to configure the SNMP Community
and Items per request.
Community name = a password for network devices.
Common options are public and private


Public usually read only
Private may allow writes if device configured for it
The common options,
public and private exist
in a dropdown, but you
may enter any
community name you
have defined in your
device.
Configuration – SNMP Communications
Request Size



Items per request used with SNMP Get or polled
requests
SNMP V2c devices typically can handle maximum
SNMP V1 devices may require 1 item/request
Set your items per
request between 1
and 25, depending on
your device
capabilities.
Configuration – SNMP Communications
Error Logging


Namespaces in SNMP devices can change
on the fly
Define how you want to handle the error
Check or Uncheck
this box depending
on if you would like to
suppress the error
messages as noted
above.
Configuration – SNMP Communications
Scan Rate Floor


SNMP scan rates are generally slower than
control rates
Use Scan Rate Floor to protect from an overdemanding client application
Set your Scan Rate
Floor and decide if
you want to lock it at
that rate for OPC
clients.
Configuration – SNMP Communications
MIB Import – What is a MIB?

The SNMP MIB, or Management Information Base for a
device, is





MIB hierarchy





A collection of variables which is shared between the network
manager and the network device.
Extensible
Hierarchical
Contain OIDs or Object Identifiers
A tree with a nameless root
Levels assigned by different organizations.
The top-level MIB OIDs belong to different standards
organizations
Lower-level object IDs are allocated by associated organizations
Managed object=MIB object=object=MIB is


One of any number of specific characteristics of a managed
device.
Managed objects are made up of one or more object instances
(identified by their OIDs), which are essentially variables.

Setting up SNMP Tags/Items


SNMP does not have “addresses” but rather object identifiers
as defined by the associated MIB files.
You do not have to set up tags as they are automatically
generated when you define your device and MIBs.
