ONFIGURING

SNMP

OVERVIEW

A Network Management Station (NMS) is a device that contains SNMP-specific software, giving it

the ability to query SNMPAgents using various SNMP commands. If you have purchased an NMS

(such as Cabletron’s SPECTRUM® Management Platform), you should enable and configure the

CyberSWITCH to be an SNMP Agent. This will allow you to use the NMS to monitor the

CyberSWITCH and other remote devices on your network. (Refer to Remote Management: SNMP.)

On the CyberSWITCH, SNMP is disabled when you first install your system software. (This is the

default.) To enable the CyberSWITCH as an SNMP agent, you must first enable IP routing, then

configure SNMP. SNMP configuration steps include:

• enabling IP routing (if not already enabled)

• enabling SNMP

• entering Community Name information

• entering SNMP trap information (optional)

• changing the MIB-2 system group objects (optional)

Notes: The SNMP management station must have the latest enterprise MIB (the ih_mib.asn

file), and the CyberSWITCH must be running the latest software release to take advantage

of the available SNMP features.

If you are using Cabletron’s SPECTRUM® Element Manager™ as NMS, the enterprise MIB

is already built into its software.

If you are using a non-Cabletron product for NMS, you must perform a copy and compile

of the latest enterprise MIB (i.e., the ih_mib.asn file) on the NMS before beginning the

CyberSWITCH SNMP configuration.

If the NMS SNMP software requires the MIB objects that it manages to be defined in a

format other than ASN.1, the NMS must have some type of “MIB Formatter” or “MIB

Compiler” software. A MIB formatter is SNMP Management Station vendor-specific

software that converts MIB data from ASN.1 format to the format understood by the given

manager. This MIB Formatter software should be executed using the ih_mib.asn file as

input.

CONFIGURING SNMP

USING CFGEDIT

Before configuring the SNMP Agent, you must have the following information:

• the Community Name(s) used in SNMP request messages generated by the Network

Management Station

• the IP address of the Network Management Station

• the Community Name to be used in Trap messages received by the Network Management

Station

The steps to configure SNMP are:
