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

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.

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
address of the TFTP server and the Þle name of the image to be downloaded.
¥ If set for TFTP or RUNTIME, the module attempts a TFTP download based on
the IP address and Þle name entered in the Þelds at the bottom of the Flash
Download Screen. See the download procedures at the end of this section.
Reboot After Download (Modifiable only when RUNTIME is chosen)

SmartTrunk Configuration Screen Fields
The following information brießy explains each SmartTrunk ConÞguration Screen
Þeld.
Port # (Read-only)
Lists each MIB II interface number capable of SmartTrunking on the selected
module. If the number of listed ports is more than twelve, then additional ports
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
connected to the same remote device or network) must be designated as
NETWORK connections to participate in SmartTrunking. To change a portÕs
connection type, press the Space Bar once. The desired value appears in the Þeld.
SmartTrunk State (Read-only)
Displays the current operating state of each listed port. The possible states
include:
NONE The port is operating as a normal bridge port.
BLOCKING The port is load sharing, but in the blocked mode. A port
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.
Instance (Read-only)
Displays the ports associated with each redundant loop. A module can have
multiple instances.
#STPorts (Read-only)
Displays the total number of load sharing ports in the redundant loop.
