2TECHNICAL SUMMARY
2.1 BRIEF DESCRIPTION
2.1.1 PREFACE
This manual describes how to install and use the OSD2700F Managed Ethernet Switch. The
OSD2700F switch is designed to deliver full scalability with SNMP/RMON web-based management
functions. To get the most out of this manual, you should have an understanding of Ethernet
networking concepts.
2.1.2 OVERVIEW
The OSD2700SFP is a managed 24-port 100BaseT and 4-port Gigabit Ethernet switch designed to
operate in tough industrial applications providing real-time redundant performance. The four 1000Base
RJ45 copper ports and four Gigabit SFP ports are combo ports - It is possible to use either the RJ45
port of the SFP port per channel (G1, G2, G3, G4). ie It is not possible to use both at the same time.
SFPs are sold separately.
The unit will operate on either 1310nm and/or 1550nm singlemode. Operation over at least 40km of
singlemode fiber is possible by use of the appropriate SFP optical devices. It normally requires two
fibers per SFP port but is optionally available for one fiber operation.
A major benefit of the OSD2700F is its reliable and consistent performance over the -10°C to +60°C
temperature range that allows it to be used in uncontrolled environments such as roadside cabinets,
mine sites and factories.

4SWITCH MANAGEMENT
This chapter explains the methods that can be used to configure management access to the switch. It
describes the types of management applications and the communication and management protocols that
deliver data between your management device (workstation or personal computer) and the system. It
also contains information about port connection options.
This chapter covers the following topics:
• Management Access Overview
• Key Concepts
• Key Guidelines for Implementation
• Web Management Access
• Administration Console Access
• SNMP Access
• Standards, Protocols, and Related Reading
4.1 MANAGEMENT ACCESS OVERVIEW
The switch gives you the flexibility to access and manage the switch using any or all of the following
methods.
The web browser interface and administration console (CLI) support are embedded in the switch
software and are available for immediate use.
4.2 ADMINISTRATION CONSOLE (CLI)
The administration console is an internal, character-oriented, Command Line Interface (CLI) for
performing system administration such as displaying statistics or changing option settings.
Using this method, you can view the administration console from a terminal, personal computer, Apple
Macintosh, or workstation connected to the switch’s console port.
There are two ways to use this management method: direct access or modem access. The following
sections describe these methods.
4.2.1 DIRECT ACCESS
Direct access to the administration console is achieved by directly connecting a terminal or a PC
equipped with a terminal-emulation program (such as HyperTerminal) to the switch console port.
When using the management method, configure the terminal-emulation program to use the following
parameters (you can change these settings after login):

OPTICAL SYSTEMS DESIGN
DOC ID: 10111504
OSD2700F OPERATOR MANUAL
PAGE 18
[Default parameters]
•115,200bps
•8 data bits
•No parity
•1 stop bit
This management method is often preferred because you can remain connected and monitor the system
during system reboots. Also, certain error messages are sent to the serial port, regardless of the
interface through which the associated action was initiated. A Macintosh or PC attachment can use any
terminal-emulation program for connecting to the terminal serial port. A workstation attachment under
UNIX can use an emulator such as TIP.
4.2.2 MODEM ACCESS
You can access the switch’s administration console from a PC or Macintosh using an external modem
attached to the console port. The switch management program provides Console Port screen,
accessible from the Basic Management screen that lets you configure parameters for modem access.
When you have configured the external modem from the administration console, the switch transmits
characters that you have entered as output on the modem port. The switch echoes characters that it
receives as input on the modem port to the current administration console session. The console appears
to be directly connected to the external modem.
4.3 WEB MANAGEMENT
The switch provides a browser interface that lets you configure and manage the switch remotely.
After you set up your IP address for the switch, you can access the switch’s web interface applications
directly in your web browser by entering the IP address of the switch. You can then use your web
browser to list and manage switch configuration parameters from one central location, just as if you
were directly connected to the switch’s console port.
4.4 SNMP-BASED NETWORK MANAGEMENT
You can use an external SNMP-based application to configure and manage the switch. This
management method requires the SNMP agent on the switch and the SNMP Network Management
Station to use the same community string. This management method, in fact, uses two community
strings: the get community string and the set community string. If the SNMP Network management
station only knows the set community string, it can read and write to the MIBs. However, if it only
knows the get community string, it can only read MIBs. The default get and set community strings
for the switch are public.

4.5 PROTOCOLS
The switch supports the following protocols:
Virtual terminal protocols, such as Telnet
A virtual terminal protocol is a software program, such as Telnet, that allows you to establish a
management session from a Macintosh, a PC, or a UNIX workstation. Because Telnet runs over
TCP/IP, you must have at least one IP address configured on the switch before you can establish access
to it with a virtual terminal protocol.
<Note> Terminal emulation is different from a virtual terminal protocol in that you must connect a
terminal directly to the console port.
Simple Network Management Protocol (SNMP)
SNMP is the standard management protocol for multivendor IP networks. SNMP supports transaction-
based queries that allow the protocol to format messages and to transmit information between reporting
devices and data-collection programs. SNMP runs on top of the User Datagram Protocol (UDP),
offering a connectionless-mode service.
4.6 MANAGEMENT ARCHITECTURE
All of the management application modules use the same Messaging Application Programming
Interface (MAPI). By unifying management methods with a single MAPI, configuration parameters set
using one method (e.g. console port) are immediately displayed the other management methods (e.g.
SNMP agent of web browser).
The management architecture of the switch adheres to the IEEE open standard. This compliance
assures customers that the switch is compatible with, and will interoperate with other solutions that
adhere to the same open standard.

5SNMP & RMON MANAGEMENT
This chapter describes the switch’s Simple Network Management Protocol (SNMP) and Remote
Monitoring (RMON) capabilities. The following documentation applies to both the OSD2700F and to
the OSD2700SFP
5.1 OVERVIEW
RMON is an abbreviation for the Remote Monitoring MIB (Management Information Base). RMON is
a system defined by the Internet Engineering Task Force (IETF) document RFC 2819, which defines
how networks can be monitored remotely.
RMONs typically consist of two components: an RMON probe and a management workstation:
•The RMON probe is an intelligent device or software agent that continually collects statistics
about a LAN segment or VLAN. The RMON probe transfers the collected data to a
management workstation on request or when a pre-defined threshold is reached.
•The management workstation collects the statistics that the RMON probe gathers. The
workstation can reside on the same network as the probe, or it can have an in-band or out-of-
band connection to the probe.
The switch provides RMON capabilities that allow network administrators to set parameters and view
statistical counters defined in MIB-II, Bridge MIB, and RMON MIB. RMON activities are performed
at a Network Management Station running an SNMP network management application with graphical
user interface.
5.2 SNMP AGENT AND MIB-2 (RFC 1213)
The SNMP Agent running on the switch manager CPU is responsible for:
•Retrieving MIB counters from various layers of software modules according to the SNMP
GET/GET NEXT frame messages.
•Setting MIB variables according to the SNMP SET frame message.
•Generating an SNMP TRAP frame message to the Network Management Station if the
threshold of a certain MIB counter is reached or if other trap conditions (such as the
following) are met:
oWarm start
oCold start
oLink up
oLink down
oAuthentication failure
oRising alarm
oFalling alarm
oTopology Alarm
MIB-II defines a set of manageable objects in various layers of the TCP/IP protocol suites. MIB-II
covers all manageable objects from layer 1 to layer 4, and, as a result, is the major SNMP MIB
supported by all vendors in the networking industry. The switch supports a complete implementation of
SNMP Agent and MIB-II.
