VERVIEW
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.

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:
