Introduction

This chapter introduces the 6E308-24 and 6E308-48 fiber optic Fast Ethernet modules.

Important Notice

Depending on the firmware version used in the module, some features described in this document
may not be supported. Refer to the Release Notes shipped with the module to determine which
features are supported.

The 6E308-24 module (Figure 1-1) features 24 10BASE-FL switched ports connected through 24
MT-RJ fiber optic connectors. The 6E308-48 module (Figure 1-1) features 48 10BASE-FL
switched ports connected through 48 MT-RJ fiber optic connectors.

Each of the fixed front panel ports can operate in either half-duplex or full-duplex mode of
operation. The default setting is half-duplex. Full-duplex must be manually configured.

Each module is a high-speed network switch that supports IEEE 802.1D switching (bridging).
Distributed Chassis Management (DCM) and SecureFast Switching (SFS) functions are not
supported when the module is installed in the MATRIX E7. Both DCM and SFS are supported for
this module when installed in the 6C105 SmartSwitch 6000 chassis.

The module ports can be configured to control traffic in several ways, including prioritizing traffic
flow according to protocol type. The module can also be configured to establish 802.1Q Virtual
Local Area Networks (VLANs) and control the flow of frames associated with each VLAN
according to priority and Ether type. Detailed information about VLANs is provided in the
Enterasys Networks MATRIX E7 Series and SmartSwitch 6000 Series Modules Local Management
User’s Guide.

The module gets power and backplane connectivity when it is inserted into an Enterasys Networks
MATRIX E7 or 6C105 chassis.

Connectivity

1.1 CONNECTIVITY

The module connects to Ethernet networks or workstations through the front panel connectors. The
ports are IEEE 802.3 10BASE-FL compliant.

1.2 RUNTIME IP ADDRESS DISCOVERY

This feature enables the module to automatically accept an IP address from a Boot Strap Protocol
(BootP) server on the network without requiring a user to enter an IP address through Local
Management.

When the module is connected to the network and powered up, Runtime IP Address Discovery
(RAD) checks the module for an IP address. If one has not yet been assigned (module IP address
set to 0.0.0.0), RAD checks to see if any of the module interfaces have a link. If a link is
discovered, RAD sends out Reverse Address Resolution Protocol (RARP) and BootP requests to
obtain an IP address from a BootP server on the network.

The RAD requests start at an interval of one per second. The interval then doubles after every
transmission until an interval of 300 seconds is reached. At this point, the interval remains at 300
seconds. The RAD requests continue until an IP address is received from a RARP or BootP server,
or an IP address is entered using Local Management.

NOTE: The module will reboot after RAD is successful.

1.3 SMARTTRUNK

Traditional 802.1D Spanning Tree bridges only allow one active data path between any two
switches; all other parallel data paths are in Standby or Blocking mode. If one interface or path
should fail, then the other interface automatically comes out of Blocking mode and forwards all of
the traffic. This is fine for redundancy purposes. However, it is not the most efficient use of
resources.

SmartTrunk, also referred to as SmartTrunking, is Enterasys Networks’ terminology for load
balancing or load sharing. SmartTrunk provides the ability to take full advantage of the network’s
redundant bandwidth. SmartTrunk divides network traffic across multiple ports in parallel to
provide additional throughput. The SmartTrunk application can be used with any of Enterasys
Networks’ switch modules (except ATM modules).

For more information about SmartTrunk and how to configure the SmartSwitch, refer to the
MATRIX E7 Series and SmartSwitch 6000 Series Modules Local Management User’s Guide.

Introduction 1-3

Remote Monitoring (RMON)

1.4 REMOTE MONITORING (RMON)

The module supports all nine Ethernet RMON groups. The Statistics, Alarms, Events and History
groups are enabled on all ports by default.

Enterasys Networks RMON Actions is a vendor-specific extension of RMON and provides the
ability to set an “Action” on any SNMP MIB variable. The Action can be triggered by any RMON
Event and/or Alarm. An example of an Action would be to turn off a MIB-2 interface if a
broadcast threshold is crossed.

1.5 BROADCAST SUPPRESSION

Broadcast Suppression enables a user to set a desired limit of receive broadcast frames per port/per
second to be forwarded out the other ports on the module. Any broadcast frames above this
specified limit are dropped. In the event that broadcast frames are being suppressed, multicast and
unicast frames continue to be switched.

1.6 PORT/VLAN REDIRECT FUNCTIONS

The port redirect function, also referred to as “Port Mirroring,” is a troubleshooting tool used to
map traffic from a single source port to a single destination port within the module. This feature
allows frames, including those with errors, to be copied and sent to an analyzer or RMON probe.
The analyzer or RMON probe will see the data as if it were directly connected to the LAN segment
of the source port.

The VLAN redirect function is similar to the port redirect function except that the frames received
by the module are redirected to a designated destination port according to the VLAN classification
of the frames received. Multiple VLANs can be directed to the same destination port. The VLAN
redirect function is only supported when the module is operating as an 802.1Q switch.

1.7 RATE LIMITING

The Rate Limiting feature enables the SmartSwitch device to control traffic rates on a per-port,
per-priority basis. The network administrator can configure a rate limit (from 100 kbps to 1 Gbps)
for a given port with an associated list of IEEE 802.1p priorities (which can include one, some, or
all of the eight priority levels defined in 802.1p). Each rate limit is specified as an inbound or an
outbound limit. The combined rate of all traffic on the port that matches the listed priorities cannot
exceed the programmed limit. If the rate exceeds the defined limit, frames are dropped until the
rate falls below the limit.

1-4 Introduction

Flow Control

Administrators can configure up to four rate limit rules per port; however, each rule must not
include conflicting 802.1p priority values. In order to control inbound and outbound traffic on the
same port, two rate limiting rules must be configured (one for inbound and one for outbound).
Since the rate limiting operation occurs after the processing of the multi-layer classification rules,
the two features can be combined to provide application-aware rate limiting.

NOTE: This Rate Limiting function is not supported on ports connected to SmartTrunk
segments.

For more information about the application of the Rate Limiting function, refer to the Enterasys
Networks MATRIX E7 Series and SmartSwitch 6000 Series Modules Local Management User’s
Guide.

1.8 FLOW CONTROL

Flow control is a method of managing the flow of frames between two devices. It ensures that a
transmitting device does not overwhelm a receiving device with data. This is accomplished by the
transmitting device pausing its transmission while the receiving device processes the frames
already received.

The module supports the following two types of flow control, which can be enabled or disabled on
a port-by-port basis.:

• Frame based 802.3x, which is supported on all Ethernet ports operating in the full-duplex mode.

• Back Pressure, which is supported on all Ethernet ports operating in the standard mode of

operation.

1.9 GARP SWITCH OPERATION

Some or all ports on the switch may be activated to operate under the Generic Attribute
Registration Protocol (GARP) applications, GARP VLAN Registration Protocol (GVRP) and/or
GARP Multicast Registration Protocol (GMRP).

GARP is a protocol, or set of rules, that outlines a mechanism for propagating the port state and/or
user information throughout a bridged LAN to keep track of users and VLANs on the network
fabric. MAC bridges and end users alike can take part in the registration and de-registration of
GARP attributes such as VLAN and multicast group membership. For more details on how GVRP
and GMRP handle frames under GARP, and how to configure the switch ports to take advantage of
this operation, refer to the Enterasys Networks MATRIX E7 Series and SmartSwitch 6000 Series
Modules Local Management User’s Guide.

Introduction 1-5

802.1 Port Priority

1.10 802.1 PORT PRIORITY

The 802.1 port priority is used to assign a default priority to the frames received without priority
information in their tag header, map prioritized frames to the appropriate transmit queues, and
prioritize frames according to protocol type. The 802.1 port priority is part of the IEEE 802.1D
standard.

1.11 DISTRIBUTED CHASSIS MANAGEMENT

Installation in the MATRIX E7 chassis

From a management perspective, 6x3xx modules in the MATRIX E7 chassis can be managed
separately by individual IP addresses. Any modules in the MATRIX E7 can be selected and
managed, however, no overall system-wide settings are available.

The MATRIX E7 chassis does not allow Distributed Chassis Management functionality
as in the 6C105 chassis. Refer to the Enterasys Networks MATRIX E7 Overview and
Setup Guide for more information.

Installation in the 6C105 SmartSwitch 6000 chassis

The 6C105 SmartSwitch 6000 chassis can be viewed as a single entity with a single IP address. Its
systems management functions are distributed to all modules, including the chassis. The chassis
can be managed using a single IP address, or the modules can be managed separately by individual
IP addresses. When the IP address of the chassis is used, system wide settings can be entered from
the chassis menu in Local Management, while module settings are entered by selecting the specific
module to be modified and changing the settings for that module.

1.12 MANAGEMENT

Management of the module can be either in-band or out-of-band. In-band remote management is
possible through any SNMP-compliant Network Management Software, such as Enterasys
Networks’ Webview and Aprisma’s SPECTRUM for Open Systems suite of management
products. Out-of-band Local Management is provided through the RJ45 COM port on the front
panel using a VT100 terminal or a VT100 terminal emulator.

Local Management, described in a separate Enterasys Networks document, provides the ability to
manage the module. Refer to the MATRIX E7 Series and SmartSwitch 6000 Series Modules Local
Management User’s Guide for more information.

1-6 Introduction

Switching Options

1.13 SWITCHING OPTIONS

The module provides 802.1Q switching between all of the front panel interfaces. In the 802.1Q
mode (the default mode of operation), the module functions as an 802.1D switch until VLANs are

Network Requirements

Before installing the module, review the requirements and specifications referred to in this chapter
concerning the following:

• SmartTrunk (Section 2.1)

• 10BASE-FL Fiber Optic Network (Section 2.2)

The network installation must meet the requirements to ensure satisfactory performance of this
equipment. Failure to do so will produce poor network performance.

The Enterasys Networks MATRIX E7 Series and SmartSwitch 6000 Series Modules
Local Management User’s Guide and Cabling Guide referred to in the following sections

can be found on the Enterasys Networks World Wide Web site:

http://www.enterasys.com/

2.1 SmartTrunk FEATURE

Before connecting the module to a network so it can take advantage of the SmartTrunk feature,
there are certain rules concerning port connections and configurations that must be followed for
proper operation. Refer to the MATRIX E7 Series and SmartSwitch 6000 Series Modules Local
Management User’s Guide for additional information.

2.2 10BASE-FL FIBER OPTIC NETWORK

The front panel ports of the module provide a connection that supports 10BASE-FL fiber optic
cabling. The device at the other end of the fiber optic segment must meet 10BASE-FL Ethernet
network requirements for the devices to operate at 10 Mbps. Make sure to check your network
diameter specifications.

10BASE-FL FIBER OPTIC REQUIREMENTS

The fiber optic link segments can consist of 50/125, 62.5/125, or 100/140 micron fiber-optic cable
segment. However, the 2.5/125 m fiber cable segment is the one that is the most implemented.

Network Requirements 2-1

10BASE-FL Fiber Optic Network

The link segment can be tested with a fiber optic attenuation test set that is adjusted for an 850 nm
wave length. This verifies that the signal loss in a cable is within an acceptable level:

• 13.0 dB or less for a 50/125 micron fiber-optic cable segment

• 16.0 dB or less for a 62.5/125 micron fiber-optic cable segment

• 19.0 dB or less for a 100/140 micron fiber-optic cable segment

When determining the maximum fiber optic cable length, the fiber optic budget and total network
propagation delay should be calculated and taken into consideration before fiber runs are
incorporated in any network design. Fiber optic budget is the combination of the optical loss due to
the fiber optic cable, in-line splices, and fiber optic connectors. Propagation delay is the amount of
time it takes a packet to travel the distance from the sending device to the receiving device and
back to the sending device.

If the system budgets are met, the maximum allowable fiber optic length is 2 km (6562 feet).
However, IEEE 802.3 FOIRL (Fiber Optic Inter-Repeater Link) specifications allow for a
maximum of 1 kilometer (3281 feet).

3.5 CONNECTING TO THE NETWORK

This section provides the procedures for connecting fiber optic cable from the network or other
devices to the module. For details on how to obtain more information, refer to the “Related

Documents” section in About This Guide.

NOTE: If the module is being installed in a network using SmartTrunking, there are
rules concerning the network cable and port configurations that must be followed for
SmartTrunking to operate properly. Before connecting the cables, refer to the MATRIX

E7 Series and SmartSwitch 6000 Series Modules (6x2xx and 6x3xx) Local
Management User’s Guide for the configuration information.

The front panel ports of the module are 10BASE-FL MT-RJ ports.

Each fiber optic link consists of two fiber optic strands within the cable: the transmit (TX) and the
receive (RX). The transmit strand from a module port connects to the receive port of a fiber optic
Fast Ethernet device at the other end of the segment. The receive strand of the applicable port on
the module connects to the transmit port of the fiber optic Fast Ethernet device.

Enterasys Networks recommends labeling fiber optic cables to indicate receive and transmit ends.
Many cables are prelabeled, providing matching labels or tapes at both ends of each strand of
cable.

The following instructions detail the process used to connect an MT-RJ connector to a module
port.

1. Remove the protective covers from the fiber optic ports on the applicable port on the device, and

from the connectors on each end of the cable.

Leave the protective covers in place when the connectors are not in use to prevent
contamination.

Do not touch the ends of the fiber optic strands, and do not let the ends come in contact
with dust, dirt, or other contaminants. Contamination of cable ends causes problems in
data transmissions. If the ends of the fiber optic strands become contaminated, use a
canned duster to blow the surfaces clean. A fiber port cleaning swab saturated with
optical-grade isopropyl alcohol may also be used to clean the ends.

2. Insert the MT-RJ fiber optic cable connector on the cable into the MT-RJ connector on the

device until it clicks into place. See Figure 3-3.

3-8 Installation

To remove the cable connector, press on its release tab and then pull the connector out
of the MT-RJ connector on the device.

4. Verify that a link exists by checking that the port RX (Receive) LED is ON (flashing amber,
blinking green, or solid green). If the RX LED is OFF and the TX (Transmit) LED is not
blinking amber, perform the following steps until it is on:

a. Check that the power on the device at the other end of the fiber optic cable is turned on.

b. Verify proper crossing over of fiber strands between the applicable port on the module and

the fiber optic device at the other end of the fiber optic cable. Check for continuity between
the two devices.

c. Verify that the fiber connection meets the dB loss specifications according to 10BASE-FL

standards. Refer to Appendix A.

If a link is not established, refer to Chapter 4 for troubleshooting instructions before contacting
Enterasys Networks. Refer to “Getting Help,” in About This Guide, for details.

3.6 COMPLETING THE INSTALLATION

After installing the module and making the connections to the network, proceed as follows:

1. If the chassis is installed in a rack that has strain-relief brackets, secure the cables by running the
cables along the strain-relief bracket and tying them to the bracket using cable ties.

2. The module is now ready to be configured through Local Management. Refer to the MATRIX E7
Series and SmartSwitch 6000 Series Modules (6x2xx and 6x3xx) Local Management User’s

B.2 SETTING THE MODE SWITCHES

CAUTION: Read the appropriate sections to be fully aware of the consequences when

changing switch settings.

Only qualified personnel should change switch settings.

Figure B-1 shows the location of the mode switches and the switch settings for normal operation.

These switches are set at the factory and rarely need to be changed.

Switch definitions and positions are as follows:

• Switches 1 through 4 – For Enterasys Networks use only.

• Switch 5 – COM Port Autobaud. The default (OFF) position enables Autobaud sensing on the

COM port for Local Management sessions. Changing the switch to the ON position disables
Autobaud sensing and sets the COM port to 9600 baud for Local Management sessions.

Setting the Mode Switches

• Switch 6 – Forced BootP.

NOTE: After changing the position of Switch 6, DO NOT reapply power to the module
until there is a station on the network acting as a BootP server, which contains the
downloadable firmware image file.

DO NOT attempt a Forced BootP unless a BootP server has been configured for the module. The
BootP server references the location of a station acting as a Trivial File Transfer Protocol
(TFTP) server containing the module image file.

When the position of Switch 6 is changed and the power is cycled to the module, the device
requests the image file location from the BootP server and uses TFTP to download the image
from the TFTP server. If one of these requirements is not met, the module continues to request
either the BootP server or the TFTP server until the RESET button on the module is pressed.
Once the RESET button is pressed, the module resets after one minute and loads the image
stored in FLASH memory.

• Switch 7 – Clear NVRAM. Changing the position of this switch resets NVRAM on the next

power-up of the module. All user-entered parameters, such as the IP address, device names, etc.,
are reset to the factory default settings. Once the module resets, you can either use the factory
default settings or reenter your own parameters.

• Switch 8 – Reset Password/Community Names. Changing the position of this switch clears

user-entered passwords stored in NVRAM, and restores the factory default passwords on the
next power-up of the device. Once the module resets, you can either use the factory default
settings or reenter your own passwords.

NOTE: Do not change the position of Switch 8 unless it is necessary to reset the
super-user configured passwords to their factory default settings.
