9M426-02 Module Specific
Information

Introduction

This appendix contains Local Management information that is speciÞc to the
9M426-02 Dual HSIM Switch Module.

This module has two slots for two High Speed Interface Module (HSIM)
interfaces (not included and may be purchased separately). These HSIMs operate
in various modes (ATM, FDDI, WAN, etc.), depending on the HSIM installed in
the module.

HSIM UserÕs Guides, in Portable Document Format, are available from the

NOTE

World Wide Web at the following site: http://www.cabletron.com/

The Listening state is entered from the Blocking state, when the
Spanning Tree Algorithm and Protocol determines that the
interface should participate in forwarding trafÞc.

The Listening state is exited in any of three ways:

¥ When a protocol timer expires (the Learning state is then

entered).

¥ When a BPDU is received on this port or another port (the

Blocking state is then entered).

¥ Through management action (either the Blocking or the

Disabled state is then entered).

Learning In the Learning state, an interface is preparing to forward trafÞc,

and is learning network addresses to minimize the forwarding of
unnecessary trafÞc.

TrafÞc that is received is discarded.

Station location information is added to the Filtering Database.

The Learning state is entered from the Listening state when a
protocol timer expires.

¥ Through management action (either the Blocking or the

Disabled state is then entered).

Forwarding In the Forwarding state, an interface is forwarding trafÞc.

Station location information is added to the Filtering Database.

The Forwarding state is entered from the Learning state.

The Forwarding state is exited in either of two ways:

¥ When a BPDU is received on this port or another port (the

¥ Through management action (either the Blocking or the

Disabled state is then entered).

Disabled In the Disabled state, an interface is not forwarding trafÞc.

TrafÞc that is received is discarded.

Station location information is not added to the Filtering Database.

Flash Download Screen Fields

The following information brießy explains each Flash Download Screen Þeld.

Download Method (Selectable)

Toggles between TFTP, RUNTIME and BOOTP.

¥ If set for BOOTP, the module sends out a BootP request to determine the IP

are listed on subsequent screens.

Port Name (Read-only)

Displays the names (assigned by Cabletron Systems) to each listed port.

Connection (Selectable)

Contains the connection type for each listed port (either USER or NETWORK).
USER connections do not participate in SmartTrunking. Only NETWORK
connections participate in SmartTrunking. At least two ports (redundantly

may be properly conÞgured for trunking but may be
blocked. If a path not involved with trunking between the
two chassis yields more bandwidth than the aggregate of
the trunking ports, the trunking ports will be placed in
blocking mode. The non-trunked, higher-bandwidth
connection will be used.

SMARTTRUNKING The port is load sharing with other Network designated

ports of the same instance.
