Token Ring Specific Configuration Screen Fields
The following information brießy explains each Token Ring SpeciÞc
ConÞguration Screen Þeld.
Source Route Bridge Number (Modifiable)
Displays and sets the Source Route Bridge Number used by the switch module.
Valid values are 0 through F (hexadecimal). The
Virtual Ring Number (Modifiable)
Displays and sets the internal Virtual Ring Number. Valid values are 000 through
FFF (hexadecimal). The
Auto-Detect Ring Number (Toggle)
default is CAC.
Automatically allows the Source Route Ring Numbers to be determined for each
port, if a Ring Parameter Server (RPS) is present on the ring segment. Valid
choices are ENABLED (
default ) or DISABLED.
default is 1.
Locally Admin Address (Read-only)
Displays the address of the port and also sets the MAC address to either of the
following:
¥ Burned-in address from the PIC (
default )
To reset to the Burned-in address, enter 00-00-00-00-00-00.
¥ User-deÞned address
The
range is 40-00-00-00-00-00 through 40-00-7F-FF-FF-FF (hexadecimal).
Media Rate (Toggle)
Sets the ring speed for the port:
¥ 4M = 4 Mbps
¥ 16M = 16 Mbps (
default )
¥ AUTO =Automatically determines the appropriate speed (either 4M or 16M)
Ring Number (Modifiable)
The source route ring number used for this port and segment. If ÒAuto-detect
Ring NumberÓ is ENABLED, then this value is automatically updated each time
the port is inserted into the ring segment from RPS responses. Valid values are 000
through FFF (hexadecimal). The
default is equal to the Token Ring port number.

9T425-16, 9T427-16, and 9T428-16 Module Specific Information
Bridging/Explorer (Toggle)
DeÞnes how the interface forwards a packet via one of the following Bridge
Methods:
¥ Source Route (
) - All frames are forwarded on the front panel Token Ring
port with a source route RIF. There is no transparent frame support. The Token
Ring port may only receive and transmit SR frames in this mode. All TP frames
are Þltered when they are received by the Token Ring interface.
¥ Source Route Transparent (
SRT ) - Performs both transparent bridging and
source route translational bridging. The Token Ring interface can receive and
transmit both SR and TP frames.
¥ Transparent (
) ( default ) - Allows TP and SR frames to be
received/forwarded. The port performs transparent 802.1d bridging. It
transmits only TP frames on the ring.
Table 2 lists the
Bridge Method Explorer Type Choices
TP (default)
Bridge methods and the corresponding Explorer types for each.
Table 2. Bridge Methods and Explorer Types
TP - Frames that are destined for an unknown destination address
(not in the bridge database) or a broadcast destination address are
forwarded out the Token Ring port as transparent (TP) frames.
This is the default .
SR
SRT
ARE - Frames that are destined for an unknown destination
address (not in the bridge database) or a broadcast destination
address are forwarded out the Token Ring port as All Route
Explorer (ARE) frames.
STE - Frames that are destined for an unknown destination
address (not in the bridge database) or a broadcast destination
address are forwarded out the Token Ring port as Spanning Tree
Explorer (STE) frames.
The ARE, STE, and TP Explorer Type choices apply only to
unknown Destination Address (DA) and Broadcast frames that are
sourced from NON-Token Ring INB modules (see deÞnitions
above).
For unknown DA and Broadcast frames that are sourced from a
Token Ring module, these frames will be transmitted on the front
panel Token Ring port just as they were originally transmitted
from the source station. In other words, if a frame is sent as an STE
frame, it will be forwarded as an STE frame out the Token Ring
port.

Novell Xlate (Toggle)
Allows Token Ring Netware IPX clients or servers operating in their default MSB
mode to communicate with FDDI or Ethernet client and servers (which operate
only in LSB mode). When enabled for LLC, the module will convert MAC
addresses for each Novell Netware frame from MSB to LSB format as each frame
is forwarded. The DLC option provides the best translation, but is limited to
support only transparent (NON-source routed) IPX frames. This option is
available on the Token Ring SpeciÞc ConÞguration LM screen and
NONE. If left set to NONE, TR devices must be conÞgured to operate in LSB
mode in order to communicate with FDDI, Fast Ethernet, or Ethernet nodes. Valid
choices are:
defaults to
¥ NONE (
default ) - No translation performed for Novell IPX/SPX packets. TR
devices must be conÞgured for LSB operation.
¥ DLC - Translation performed within the data link control layer for Novell
IPX/SPX packets. This selection is valid for ports conÞgured with the Bridge
Method set to TP or SRT only. Only the 9T427-16 supports this for SR mode.
¥ LLC - Translation performed within the Logical Link Control layer for Novell
IPX/SPX packets (provides MSB-to-LSB MAC address conversion).
C-Port Mode (Toggle) - 9T425-16 & 9T427-16
ConÞgures the port to one of the following choices:
¥ AUTO ( default ) - Automatically determines the correct port mode (either
LOBE or STN).
¥ LOBE - Allows direct-attach station connections (acting as a concentrator port).
¥ STN - Provides station emulation and sources phantom drive.
C-Port Mode (Toggle) - 9T428-16 Only
ConÞgures the port to one of the following choices:
¥ STN/RI ( default ) - Provides station emulation and sources Þber optic key. Also
provides Ring In port; compatible to attach with 802.5 Ring Out ports.
¥ LOBE - Allows direct-attach Þber optic station connections or stations
converted by TRFOT-2
¥ TPIM - Allows for connection to Cabletron Þber optic RI/RO ports using
TPIM-F2, TRFOT-2 (in RI/RO application), or TDRMIM conÞgured for
Cabletron (ctron) Þber optic keying.

Duplex Mode (Toggle)
ConÞgures the port to one of the following choices:
¥ AUTO ( default ) -ConÞgures the port to automatically determine at insertion
time whether to operate in Full (TXI) or Half (TKP) Duplex mode.
¥ FULL - ConÞgures the port to only operate with a device that supports Full
Duplex (TXI) mode. Classic TR devices that only support Half Duplex (TKP)
mode will not connect to the port.
¥ HALF - ConÞgures the port to only operate with a device that operates in Half
Duplex (TKP) mode. DTR (TXI capable) devices will be denied the ability to
use Full Duplex (TXI) mode.
