Appendix
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.
Modifying Fields and User Privileges
To modify Þelds on this module, you must have read-write or super-user
privileges. If you have read-only privileges, you can view information; however,
you cannot modify any Þelds. For more information about user privileges and
community names, refer to the
SmartSwitch 9000 Module Local Management UserÕs
Guide.
HSIM UserÕs Guides, in Portable Document Format, are available from the
World Wide Web at the following site: http://www.cabletron.com/

Module Interfaces
The 9M426-02 Module can have as few as 8, and as many as 112, interfaces.
Table 1 lists the identifying number, name, and description of each interface.
If the HSIMs installed are ATM, ports 9Ð112 are ATM virtual ports.
The default interface is limited to SMB10 (Interface 2) or the HOST (Interface 3) on
the General ConÞguration Screen.

The port numbering for Table 1 is MIB II interface numbering.
The port numbering for this screen is 802.1D Bridge Port numbering.
- Port 1 corresponds to the INB.
- Ports 2 & 3 correspond to HSIM1.
- Ports 4 & 5 correspond to HSIM2.
NOTE
Information for up to 8 ports can appear on the screen. If additional ports exist, a
command containing the range of ports, such as [ 9-16 ], appears on the command
line at the bottom of the screen. To view any additional ports, highlight the range
of ports command, and then press the Return key.

Switch Configuration Screen Fields
The following information brießy explains each Switch ConÞguration Screen
Þeld.
Switch Address (Read-Only)
Displays the MAC address of the switch.
Number of Ports (Read-Only)
Displays the total number of switched ports on the module.
Type of STA (Selectable)
Allows you to set the method that switches use to decide which switch is the
controlling (Root) switch when two or more switches exist in parallel (Spanning
Tree Algorithm). Valid entries include IEEE, DEC, and NONE.
Port # (Read-Only)
Lists each switch port on the module.
MAC Address (Read-Only)
Displays the hardware address assigned to each listed port.
State (Read-Only)
Displays the current state of each listed interface. The possible interface states
include:
Blocking In the Blocking state, an interface is not forwarding trafÞc.
TrafÞc that is received is discarded.
Station location information is not added to the Filtering Database.
The Blocking state can be entered from the Listening, Learning, or
Forwarding states.
The port numbering for Table 1 is MIB II interface numbering.
The port numbering for the Switch ConÞguration Screen is 802.1D Bridge Port
numbering.
- Port 1 corresponds to the INB.
- Ports 2 & 3 correspond to HSIM1.
- Ports 4 & 5 correspond to HSIM2.

The Blocking state is entered in either of two ways:
¥ Following initialization of the switch.
¥ From the Disabled state when management enables the
interface.
The Blocking state is exited in any of three ways:
¥ When a protocol timer expires.
¥ When a ConÞguration BPDU is received on this port or another
port.
¥ Through management action.
Listening In the Listening state, an interface is preparing to forward trafÞc.
TrafÞc that is received is discarded.
Station location information is not added to the Filtering Database.
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.

9M426-02 Module Specific Information
The Learning 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).
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
Blocking state is then entered).
¥ 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.
The Disabled state is entered from any other state through
management action.
The Disabled state is exited when the port is enabled by
management action (the Blocking state is entered).
Status (Toggle)
Allows you to enable or disable a port by setting the status of the listed interface
to either ENABLED or DISABLED.
