Introduction

The 9E531-24 shown in Figure 1-1, is a 10BASE-FL Ethernet switching module for Cabletron Systems SmartSwitch 9000 chassis, providing 24 MT-RJ MMF ports.

The 9E531-24 can be used to connect individual 10 BASE-FL user devices and servers.

Features

Connectivity

The 9H532-24 connects to Ethernet networks or workstations through the 24 MTRJ ports on the front panel. These ports are IEEE 802.1D and 802.3 10BASE-FL compliant. The ports support Multimode fiber cables with attenuation of less than or equal to 3.75 dB/Km, when measured at a wavelength of 850 nm.

Introduction

Duplex Mode

Through Local Management, each port on the 9E531-24 can be configured to support either full or half duplex mode of operation.

Runtime IP Address Discovery

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

When the modules are connected to the network and powered up, Runtime IP Address Discovery (RAD) checks the modules for an IP addr ess. If one has not yet been assigned (module and SmartSwitch 9000 chassis IP address set to 0.0.0.0), RAD checks to see if any of the module interfaces have a link. If so, RAD sends out Reverse Address Resolution Protocol (RARP) and BootP requests to obtain an IP address from a RARP or 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 rec eived fr om a RARP or BootP server, or an IP address is enter ed using Local Management.

SmartTrunk

SmartTrunk, also referred to as SmartTrunking, is Cabletron Systems’ terminology for load balancing or load sharing. SmartTrunk technology provides an easy-to-implement mechanism to group, or aggregate, multiple links of any technology together to scale the backbone bandwidth beyond the limitations of a single link. All links are user-configurable so administrators can scale the backbone bandwidth by adding SmartTrunk links. The benefits of SmartTrunking include the following:

• All purchased bandwidth is used.

• Distributed, resilient links increase reliability and performance.

• Multiple technologies are supported within a single trunk for maximum flexibility.

For information on SmartTrunk configuration, refer to the

NOTE

SmartTrunk User’s Guide.

Introduction

Management

Management of the 9E531-24 module and SmartSwitch chassis and any optional equipment is accomplished using the Local Management application or remote SNMP management stations. Local Management is accessible through the RS232 COM port on the Environmental Module using a local VT100 terminal, or a remote VT100 terminal via a modem connection, and in-band via a Telnet connection. In-band remote management is possible through Webview or any SNMP compliant Network Management Software.

Local Management provides the ability to manage the 9E531-24. Local Management information for non-Eth ernet HSIMs or VHSIMs is incl uded in t heir

respective user’s guide. For details on how to get manuals, refer to the Related Manuals section in the Introduction.

WebView

The 9E531-24 modules can be managed by Cabletron WebView, a browser-based utility. There is no software to install as this management capability is b uilt into each module.

Remote Monitoring (RMON)

The 9E531-24 supports all nine Ethernet RMON groups. The Statistics, Alarms, Events and History groups are enabled on all ports by default.

Cabletron Systems RMON Actions is a vendor-specific extension of RMON and provides the ability to s et an “Action ” on any SNMP MIB variabl e. The Action can be triggered by setting an 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.

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 up to the set limit. 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.

Port Redirect Function

The Port Redirect function, also referred to as “Port Mirroring,” is a troubleshooting tool used to map traff ic from a single source port to a destination port within the chassis. This feature allows all packets, 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 i f it is directly connected to the LAN segment of the source port.

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 enables the receiving device to communicate with the transmitting

1-4

Introduction

device, and to have it pause its transmission while the receiving device processes the frames already receive d. Flow contro l can be e nabled or disabl ed on a port-byport basis. Both devices must support the IEEE 802.3x standard for flow control to work.

The 9E531-24 supports the following two types of flow control:

• frame based 802.3x

• back pressure

Frame based 802.3x flow control is supported on all Ethernet ports operating in the full duplex mode.

Back pressure flow control is supported on all Ethernet ports operating in the standard mode of operation.

802.1p Port Priority

The IEEE 802.1p standard is used to assign a default priority to the frames received without priority information in their tag header, and to map prioritized frames to the appropriate transmit queues.

The default priority-to-queue mappings are shown in Table 1-1. This configuration can be changed by the admi nistrator.

Table 1-1. Priority Queuing Configuration

Priority Indicator Transmit Queue

73 63 52 42 31 20 10 01

Switching Options

The 9E531-24 provides IEEE Standard-based 802.1 switching or SecureFast Switching Virtual Network Services. In the 802.1 mode (the default mode of operation), the switch functions as an 802.1D switch. When VLANs are configured, it operates as an 802.1Q switch.

1-5

Introduction

Standards Compatibility

The 9E531-24 is fully compliant with the IEEE 802.3, 802.3x, 802.1Q, and 802.1p standards. The 9E531-24 provides IEEE 802.1D Spanning Tree Algorithm (STA) support to enhance the overall reliability of the network and protect against

“loop” conditions. The 9E531-24 supports a wide variety of industry standard MIBs including RFC 1573 (MIB II), RFC 1271 (RMON), RFC 1493 (Bridge MIB), RFC 1354 (FIB MIB), and RFC 1190 (Path MTU Discovery). A full suite of Cabletron Systems Enterprise MIBs pr ovide a wide array of st atistical i nformation to enhance troubleshooting.

For information about how to extract and compile individual MIBs, contact Cabletron Systems.

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 d e-r egistration of GARP attributes such as VLAN and multicast group membership.

LANVIEW Diagnostic LEDs

LANVIEW diagnostic LEDs serve as an important troubleshooting aid by providing an easy way to observe the status of individual ports and overall network operations.

Year 2000 Compliance

The 9E531-24 module and the SmartSwitch 9000 chassis have an internal clock that can maintain the time and date beyond the year 1999.

Installing the SmartSwitch 9000 Module

Using DIP Switch 6

The purpose of DIP switch 6 is to force a Flash download from a BootP server through the EM-EPIM. The first step in this process is to configure the BootP server. Configurations of BootP servers can differ from platform to platform and

from one operating system to another. Read the user’s manual on BootP and TFTP serving for the correct files to edit and the correct files to execute for the server. After configuration of the BootP server the module can then have the switch state changed on dip switch 6 to initiate BootP and TFTP requests.

When the state of dip switch 6 is changed, the module begins requesting a BootP server in an attempt to receive a Flash ima ge download. The modules boot PROM initiates a BootP sequence. During this sequence, the module requests an IP address and a filename from the BootP server. The module then requests a TFTP of the file and receives the download of the image. The module will not function until the Flash image is downloaded from the BootP and TFTP server.

If a BootP and TFTP are not intended at this time, this process may be stopped by resetting the module. Resetting is done by pushing the reset button on the module, power cycling the chassis, or removing the module from the chassis and re-inserting. (See section titled module again looks for a BootP server, but will time-out after about f our min utes. After the time-out, the module boots from Flash memory. The next time the power is cycled, the module will boot from Flash memory and not request the BootP server.

Technical Overview

SmartSwitch Architecture

The SmartSwitch Architecture of the 9E531-24 module, as shown in Figure 3-1, is configurable for one of two modes of operation: traditional IEEE 802.1 switching, or SecureFast switching. The module supports only one of these modes of operation at any one time.

When operating in traditional IEEE 802.1 switch mode, the 9E531-24 makes filtering/forwarding decisions based on Destination Addr ess (DA), with standard IEEE 802.1D learning. 802.1Q VLANs are also supported.

Spanning tree operation for the 9E531-24 is config urable to adher e to IEEE 802.1D , DEC, or none. The default Spanning Tree Algorithm is 802.1D.

Chapter 3

When operating in SecureFast switch mode, al l filtering/forwar ding decis ions are made on a DA-SA pair and its in and out port on a connection-orientated basis. SecureFast switching mode provides value-added network services including dynamic VLANs, Topology, Connectivity, IP Multicast, Control, Security, Application, Address Management, Dynamic Mapping, and Directory services. For example, Topology Services includes configurable options ranging from simple spanning tree implementations to fully-meshed active topologies. Other services and features supported in SecureFast switching mode are described in detail in the Cabletr on W hite Paper, IP Host Communication in Bridged, Routed and SecureFast Networks.

System Management Buses

There are two management channels within the SmartSwitch 9000 system: the SMB-1 and the SMB-10. These buses provide out-of-band management and inter-module management communication.

3-2

SMB-1 Bus

The SMB-1 is a 1 Mbps management bus located within the SmartSwitch 9000. This bus is utilized by all diagnostic controllers in the system including connectivity modules, power supply modules and the environmental module. The SMB-1 transports inter-chassis information between system components, such as power and environmental information, as well as diagnostic messages. Periodic loop-back tests are performed by all modules that share this bus to ensure the validity of SMB-1. In the event a failure is detected on SMB-1, the SMB-10 may be used as an alternate communication channel.

SMB-10 Bus

The SMB-10 is a 10 Mbps management bus located within the SmartSwitch 9000, which is also used for inter-chassis communication of modules as well as serving as an out-of-band management ch annel i nto the SmartSwitc h 9000 . The SMB-10 is externalized from the chassis via an optional Ethernet Port Interface Module (EPIM) located on the front of the Environ mental Module. Through an EPIM connection, full SNMP management of the SmartSwitch 9000 is available out-ofband from user data. Modules which share the SMB-10 bus periodically send out loop-back packets to ensure the validit y of SMB-10. In t he event a fault is detected on the SMB-10, the SMB-1 can be used as an alternate communication chan nel by the modules.

Technical Overview

System Diagnostic Controller

This diagnostic controller is composed of a Z-80 microprocessor and its supporting logic. The diagnostic controller is designed to control the power-up sequencing of modules, monitor the 9E531-24 input and output power parameters, keep watch over the main host processor, as well as monitor the temperature and control the SMB LANVIEW diagnostic LED. Although the diagnostic controller and the main host processor can operate independent of

each other if needed, they exchange information about each other’s status and overall module condition. The information gathered by the diagnostic controller is available to the network manager via local/remote management and the LCD located on the Environmental Module. Th e 9E531- 24 has been designed so that in the event of a diagnostic controller fault, the 9E531-24 will continue to function.

DC/DC Converter

The DC/DC converter converts the 48 VDC on the system power bus to the necessary operating voltages for its host network se rvices module . The di agnostic controller monitors and controls the operation of the DC/DC converter.

3-3

Technical Overview

INB Interface

Each module attaches to both INB A and INB B and has two INB ASICs. The INB ASICs use 64-byte Ethernet frames for transmission onto the INBs at 66 MHz.

The 9X5XX modules are fully compatible with the the first generation 9X4XX modules. The first generation modules communicate only on INB B using a 56-byte canonical frame format, at 40 MHz. If the newer module detects a first generation module on the backplane, it automatically changes from the fast 66 MHz Ethernet frames, to the first generation compatible 40 MHz canonical frame on INB B only. INB A is used only by the 9X5XX modules and remains at the higher speed.

i960 Core

The i960 core provides modules host services, the SNMP protocol stacks, to support industry standard MIBs, as well as Cabletron enterprise extension MIBs for each media type. Management services, such as telnet , WebV ie w and network address to MAC address mapping, are also provided by the i960 core.
