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 ex isting
legacy Token Ring networks and ATM networks.

Note: References to STS16-20RM are also applicable to STS16-20FRM.

The SSIM-Ax-01 module mou nt s in one of the two fron t- panel expansion module
slots on the switch. The SmartStack SSIM-A2-01 has a UTP-5 copper shielded
RJ-45 connector interface. The SmartStack SSIM-A8-01 is available for
multimode optical fiber with duplex SC connector.

1

Figure 1.

The modules support Token Ring LAN Emulation (LANE) 1.0, UNI 3.0/3.1/4.0
and Integrated Local Management Interface (ILMI) 4.0.

A single ATM interface can emulate up to 63 Virtual ATM Ports (VAPs), each
implementing a separate LANE bridge (LANE proxy client). Virtual ATM ports
support nearly all of the features of standard Token Ring ports, and are co nfigured
just like any other Token Ring port. Extra configuration options are available for
configuring the LAN emulation and ATM interface options.

The bandwidth of the ATM interface is shared among multiple VAPs.
Additionally, advanced traffic configuration facilities eliminate transmit overloads
and permit the optimization of bandwidth usage.

Rules to Remember

This section will help you understand the configuration restrictions for the SSIM­Ax-01 ATM 155 Uplink Module. In brief, y ou mus t rememb er the fol lowing r ules
when planning to install the uplink:

Only one VAP per uplink per VLAN

•

If you create parallel paths directly between switches, spanning tree must be

•

enabled
Configuration data follows the switch slot, not the uplink module

•

Frame Length Limit

When attaching to an ATM network with LANE, possible ATM frame sizes are
1516, 4544, 9234 and 18190 bytes.

The LANE frame size (

You must configure yo ur To ken R i ng st at ions to a maxi mu m frame s ize as ab ove,

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. Therefore, the configuration shown in Figure 2 is

supported.

not

Figure 2. Unsupported Configuration

If you want to connect the same STS16-20RM Token Ring Switch to ATM via
more than one VAP, the VAPs must reside on different ATM uplink modules, as
shown in Figure 3.

Figure 3. Connecting One Switch to Two VAPs

SmartStack SSIM-A2-01/SSIM-A8-01 Installation

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 pat hs.

With more than one uplink, you can connect more VLANs to ATM while at that
same time creating back up connections. Figure 4 s hows two uplink modules, each
connected to two ATM ELANs. The lighter arrow shows the parallel path in the
spanning tree “blocked” state (the path is on “standby”).

Figure 4. Connecting VLANs to ATM

Spanning Tree

If you create parallel paths in your network topology, but fail to enable the spanning
tree protocol, you risk “b road cast sto rms” th at can d isrupt you r en tire n etwork . To
enable spanning tree, see section “Spanning Tree Menu” in the STS16-20RM
switch manual. The default setting for spanning tree is disabled.

Configuration Data

When you configure an uplink module in a switch, the configuration data is applied
to any uplink in that particular switch slot. This means that the config uration data
does not move with the uplink module if the module is moved to another slot or
another switch. Conversely, configuration data is retained if one uplink is replaced
with another.

Note, however, that the SSIM-Ax-01 module software image is stored in the
module itself and will follow the module when it is moved to another switch.

SmartStack SSIM-A2-01/SSIM-A8-01 Installation

Installation Procedure

The SSIM-Ax-01 module is packaged with software for both the module and the
base STS16-20R M Token Ring Switch. The switch is also packaged with soft ware
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. The switch
and module software is also available via Cabletron’s online services, such as the
Internet.

When installing the module, follow the procedure lis ted below:

1. Install the software in the switch. See the switch manual for instructions on
downloading software.

2. Optional: clear NVRAM in the base switch. This will erase all configuration in
the switch.

3. Reset the switch to activate the new software.

7

4. If you cleared NVRAM in step 2, re-establish the switch configuration. Verify
that the switch is operating correctly.

5. Turn off the switch.

6. Physically install the module in one of the two expansion slots. See section
“Hardware Installation” on page 8.

7. Turn on the switch.

8. Download the software for the module. See section “Software Installation” on
page 9.

9. If you plan to use the graphical switch manager, install it now.

10.If necessary, configure the module. F o r deta il s , see sect i on “Configuration” on
page 14 as well as Chapter 3, “Console Configuration”.

Token Ri ng Switch:

1. Power o ff t he base swi tch b y unpluggi ng the po wer cord from the po wer ou tlet.
If the switch uses the optional SmartStack STS-PSU Redundant Power Supply
Unit, unplug the connector from the base switch as well.

2. Select an empty expansion module slot in which to install the module. You can
install the module in either or both of the slots.

3. Remove the blind plate covering the expansion module slot on the front of the
STS16-20RM b y loosening the two retai ning thumbscre ws (Figure 5). Keep the
plate for use in the event that the expansion module is removed.

➽

Figure 5. Removing the Expansion Slot Cover

Warning:

Expansion modules are

hot-swappable. If you install or remove

not

expansion modules while the power to the switch is on, damage may occur to the
switch and to the module.

4. Carefully insert the module into the rails on each side of the expansion slot,
sliding it back until the connector on the module is seated into the connector at
the back of the slot (Figure 6). When the module is fully seated, the module
faceplate will be flush with the front of the base switch.

Testing the Module

1. Powe r on the base sw itch to st art diagnostic s. Diagnost ics are in pr ogress 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 diagnostic s are
in progress.

2. Verify that the base switch diagnostics have been completed successfully. You

can see that diagnostics have been completed successfully when the switch
DIAG LED turns off and the ERR LED stays off. Diagnostics can take up to
four minutes to complete.

3. Verify that the SSIM-Ax-01 ERR LED is of f. If th e ERR LED is of f, diagno stics

have been successfully completed, and the module is ready for 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 SNMP­based 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:

One VAP in the default CRF.

•

LANE services using the LECS address con figured in the switch, subs equently

•

LECS at the LANE well-known address.
The ELAN name will be empty.

•

The maximum data frame size is 4544 (and the LAN type is Token Ring).

•

The signaling version is UNI 3.1.

•

The framing type is SONET.

•

You will need to reconfigure the module in the following cases:

If you want to change any of the defaults listed above.

•

If you want to change any of the more advanced parameters not listed above.

•

If you want to connect other CRFs than the default CRF to ATM.

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 STS16­20RM Token Ring Switch. The module config uration can also be modified from a
remote VT100 console via a telnet session. Connecting a network management
console is explained in the manual supplied with the switch.

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. The ATM ports can be configured just like the
ordinary switch ports. They will appear as additional ports on any configuration
panel where ports are listed.

As a significant difference from the ordinary Token Ring ports, the ATM ports can
work as trunk ports, which means that they can carry traffic belonging to all
possible 63 VLANs over the same physical cable connection. That is, each ATM
port is divided into vi rtual ATM ports (VAPs). In the defaul t configuration an ATM
port will have one VAP in the default CRF. Assigning an ATM por t to se veral
CRFs will create new VAPs, but there can be only one VAP per BRF/VLAN.

After a VAP has been established as described above, you can configure the VAP
from the Port Configuration menu. Manually added VAPs will have the sam e
settings as the default VAP, except that the ELAN name will be set to the name of
the CRF. Note that a BRF (VLAN) can only be connected to any ATM ELAN once
on the same ATM module. This means that if more than one CRF is attached to
ATM by the same ATM module, the CRFs must connect to different ELANs.
