COMSPHERE 6800 Series Network Management System
SNMP Trap Export Feature

Installation and Enabling/Disabling Instructions

Document Number 6800-A2-GZ45-00

April 1994

Overview

The 6800 Series Network Management System (NMS) SNMP (Simple Network Management Protocol) Trap
Export feature enhances the interoperability between the 6800 Series NMS and most industry-standard,
SNMP-based network management systems. This feature exports native 6800 Series NMS alerts as standard
SNMP traps. All traps are generated as enterprise specific.

Variable Bindings Information

The 6800 Series NMS alert information is packed into the variable bindings. The fields from the Common
Alert Format of the 6800 Series NMS that are put into the variable bindings are the following:

• Device T ype

• Device Address

• Alert Type

• Alert Text

Each of these fields is handled as a separate MIB (Management Information Base) variable. (The entire MIB
definition is registered formally.) These SNMP alerts are forwarded on the TCP/IP network. In this context, the
term TCP/IP network refers to the entire internet suite of protocols. Traps can be forwarded to any specified
SNMP Manager on the network. The SNMP Manager may require a formal definition of the variable bindings
to be parsed into its MIB definitions. Also, users must specify the internet address of the SNMP Manager on the
6800 Series NMS host. Both of these requirements are discussed in the installation instructions provided in this
document. The traps community string will always be public.

Object Identifier

The SNMP traps forwarded from the 6800 Series NMS contain a single object identifier, the 6800 NMS, which
is registered under the att-management sub-tree. The fully distinguished name for this object is the following:

iso(1).identified-organization(3).dod(6).internet(1).private(4).enterprise(1).att-2(74).att-mgmt(2).paradyneNMS(23)

User Features

For users requiring the flexibility to turn trap forwarding on and off and to provide a more customized filtering
mechanism for traps, the following user features are provided.

• User facility to turn the trap forwarding on/off.

• Forwarding ability for selected alerts using the UAI (Uniform Alarm Interface) Filter; that is, any new

alerts passing the UAI filter are forwarded as an SNMP trap. Existing alerts will not be forwarded on
start-up. Alert clears and alert updates will never be sent.

• Ability to view alerts on the SNMP Manager from the X-workstation. Refer to the COMSPHERE

6800 Series Network Management System User’s/System Administrator’s Guide, Appendix I, for more
information on X-window cut-through for the SNMP Manager and the COMSPHERE 6800 Series
Network Management System Installation and Maintenance Guide for more information on connecting

the components.

NOTE

In the device profile, the ability to turn the forwarding mechanism
within UAI on/off is not supported for SNMP traps. That is, alerts for
SNMP will always be sent at the device level.

Network Interface

The SNMP Trap Export feature assumes that the SNMP Manager is connected to the 6800 Series NMS via the
TCP/IP network. There is no limitation on the physical medium. It could be Ethernet, which is the most
commonly used physical interface. The SNMP trap forwarding server will use the Transport Layer Interface
(TLI) to access the network services. It will use the User Datagram Protocol (UDP) as the transport layer. This
is a connection-less service without guaranteed delivery. This is the standard requirement for all SNMP PDUs
(Protocol Data Units).

Installation Notes

The SNMP Trap Export feature is contained on three diskettes:

1. NMS 6800 install diskette

2. DOS MIB diskette

3. UNIX MIB diskette

The first diskette contains the install script which enables the trap forwarding server. The remaining diskettes
provide the variable binding MIB definition, one for UNIX and the other for DOS. T ypically, any two of these
three diskettes are used during installation. The installation must be done in the super-user mode. Hence, before
starting the installation, you must login as root and change the directory to /tmp.

After installing the software, you must enable the feature using the trpEnable command described later in this
document. This document describes the TrpDisable command for disabling the feature as well.
