  • Page 10: Introduction

    1. Introduction The SmartStack SSIM-A2-01 and SmartStack SSIM-A8-01 ATM 155 Uplink Modules from Cabletron Systems provide high-speed connections to the ATM backbone for the STS16-20RM Token-Ring Switch. Designed for high performance and low latency, these modules provide connectivity between existing legacy Token Ring networks and ATM networks.

  • Page 13: Rules To Remember

    Rules to Remember This section will help you understand the configuration restrictions for the SSIM- Ax-01 ATM 155 Uplink Module. In brief, you must remember the following rules when planning to install the uplink: • Only one VAP per uplink per VLAN •...

  • Page 14: One Vap Per Uplink Per Vlan

    One VAP per Uplink per VLAN The SSIM-Ax-01 module does not allow configurations in which the following frame operations take place within a single uplink module: • Bridging from ATM back to ATM. • Broadcasting a frame from Token Ring to more than one ATM ELAN. These operations would occur if the uplink module provided more than one VAP per VLAN.

  • Page 15: Spanning Tree

    If you connect to the same ATM ELAN more than once from the same VLAN, you are using parallel bridges. When doing so, you must always enable the Spanning Tree function for all the CRFs that have parallel paths. With more than one uplink, you can connect more VLANs to ATM while at that same time creating backup connections.

  • Page 16: Installation Procedure

    Installation Procedure The SSIM-Ax-01 module is packaged with software for both the module and the base STS16-20RM Token Ring Switch. The switch is also packaged with software for both the module and the switch. To ensure compatibility between the module and the switch, you must install the later of the two software revisions.

  • Page 17: Hardware Installation

    Hardware Installation Use the following steps to install the SSIM-Ax-01 module in a STS16-20RM Token Ring Switch: 1. Power off the base switch by unplugging the power cord from the power outlet. If the switch uses the optional SmartStack STS-PSU Redundant Power Supply Unit, unplug the connector from the base switch as well.

  • Page 18: Software Installation

    Software Installation Before you can use your SSIM-Ax-01 module, you must install the uplink module software. The module software can be downloaded via TFTP or via a serial line. Search the disks supplied with the module for a file named ATMyzv.bin. The letters yzv in the file name represent the version number of the software.

  • Page 19: Serial Download

    The console will display the download activity while the software is transferred over the network. When the software has been transferred, you will see the following messages: Network download complete. Now transferring to ATM Module(s), please wait... Download of ATM firmware complete - ATM module(s) being reinitialized...

  • Page 20: Cabling

    Cabling The cabling used depends on which version of the module you are installing. SSIM-A2-01 ATM 155 Uplink UTP5 The SSM-A2-01 module uses standard copper UTP5 cabling. The maximum cable length is 100 m (328 feet). 1. Insert the modular jack from either end of an RJ45 UTP-5 cable into the connector on the SSM-A2-01 front panel.

  • Page 21: Leds

    LEDs There are four LEDs on the front panel of the SSIM-Ax-01 module. The LEDs show the module status and activity. Table 2 explains the status LEDs on the left of the module front panel, and Table 3 explains the ATM interface LEDs on the right of the module front panel.

  • Page 22: Testing The Module

    State DIAG RXSYNC On (green) SIGLOSS Table 4. Normal LED State Testing the Module 1. Power on the base switch to start diagnostics. Diagnostics are in progress when the STS16-20RM DIAG LED is on. After about a minute, the SSIM-Ax-01 DIAG LED will turn on, indicating that the expansion module diagnostics are in progress.

  • Page 23: Configuration

    Configuration The SSIM-Ax-01 module can be configured using the RS-232-based console configuration, Telnet, or the SNMP-based management application. (The SNMP- based management application is described in the online help). Default Configuration When the module is inserted for the first time, the module will be configured with the default configuration, as described below: •...

  • Page 24: Console Configuration

    3. Console Configuration This chapter explains how to view and edit the configuration of the SSIM-Ax-01 ATM 155 Uplink Module using a VT100 console attached directly to the STS16- 20RM Token Ring Switch. The module configuration can also be modified from a remote VT100 console via a telnet session.

  • Page 25: Introduction

    Introduction In the console configuration, port numbers are used to refer to ports, with the ordinary Token Ring ports being numbered 1 to 20. Using the console, the ATM port will appear as port 21 when located in the left hand slot, and as port 25 when located in the right hand slot.

  • Page 38: Traffic Profiles

    Traffic Profiles Traffic profiles describe the characteristics of the transmitted data. All VCCs (SVC or PVC) created by the uplink software and the LES are assigned a traffic profile, and for the typical ATM LAN setup, the default profile is sufficient. However, under certain circumstances it may be necessary to change the traffic profiles and their usage.
  • Page 39 Traffic profiles are used in three different situations, listed below, which again require three different methods for assigning the correct traffic profiles to the correct VCC. 1. PVCs are assigned a designated traffic profile when they are created during startup. The designated profile is simply specified in the configuration. 2.
