FNB Resource Configuration Codes
The 9T125-24 Token Ring MicroLAN Switch Module provides connectivity
between either two or three interfaces: the front panel Token Ring interface(s) and
the FDDI rings on the backplane (FNB-1 or FNB-2).
The FNB Resource Configuration Screen allows you to connect the module’s front
panel Token Ring interface to one of the chassis’ two FDDI networks (FNB-1 or
FNB-2) via a bridge/switch.
The FNB Resource Configuration Screen lists all the possible connections that the
specified module can support on the FNB, displays the current connection, and
allows you to change the connection. Table 2 lists and describes the FDDI
Connections from which you can select.

Connections Description
1 NORING <-> TRNG
Neither the FNB-1 nor the FNB-2 on
the chassis’ backplane is connected
to the module’s bridge/switch.
2 FNB1 <-> TRNG
The FNB-1 on the chassis’ backplane
and the module’s front panel Token
Ring interface is connected to the
same bridge/switch.
3 FNB2 <-> TRNG
The FNB-2 on the chassis’ backplane
and the module’s front panel Token
Ring interface is connected to the
same bridge/switch.

General Configuration Screen Fields
The following information briefly explains each General Configuration Screen
field.
Module Serial #
Displays the serial number of the selected module.
Module Board Revision
Displays the version number of the selected module.
FLASH Memory
Displays the amount (megabytes) of flash memory in the selected module.
Module Date
Contains a value that the module recognizes as the current date. To enter a new
date, highlight the field and enter the date in MM/DD/YYYY format. The month
and day portion of the date must include two digits. Therefore, enter a leading
zero for months January through September, and for dates less than 10. For
example, for June 4, 1996, enter 06/04/1996 (slashes are optional). If you do not
enter slashes to separate the month, day, and year values, the first eight digits you
enter in this field represent an entry (i.e., 06041996).
ModuleTime
Contains a value that the module recognizes as the current time. To enter a new
time, highlight the field and enter the time in HH:MM:SS format. Notice that
there is no AM/PM indicator. Time should be entered based upon a 24 hour clock.
For 4:07 p.m., enter 16:07:00 (colons are optional). If you do not enter colons to
separate the hours, minutes, and seconds values, the first six digits you enter in
this field represent an entry (i.e., 160700). For 6:12 a.m., enter 6:12:00 or 061200.
Screen RefreshTime
Contains the rate at which the module’s screens are updated. This setting
determines how frequently (in seconds) information is updated on the screen. To
enter a new refresh rate, highlight the field and enter a number. The default
refresh rate is 3 seconds. The range is 3 - 99 seconds.
The module’s default date and time settings are indeterminate. The internal
calendar and clock begin running as soon as you install the module.
NOTE

9T125-24 Module Specific Information
Screen LockoutTime
Contains the maximum number of minutes that the Local Management
application will display a module’s screen while pending input or action from a
user. For example, if you enter 5 in this field, users will have up to five minutes to
respond in some fashion to each of the specified module’s Local Management
screens. In our example, after five minutes of “idleness” (no input or action), the
Local Management application terminates the session on the selected module and
the Slot Selection Screen reappears. To enter a new lockout time, highlight the
field and enter a number. The default lockout time is 15 minutes. The range is 1 -
30 minutes.
Host IP Address
Contains the Internet Protocol address currently assigned to the selected module.
Set this field according to your network requirements. Highlight the Host IP
Address field and enter the desired IP address using dotted decimal notation (4
decimal values between 1 and 255 separated by periods) as follows:
255.255.255.255
(255 is the maximum number that you can enter in any of the four segments.
Default = 0.0.0.0 .) This address can be used by any of the system interfaces on
the module.
Subnet Mask
Contains the subnet mask for the selected module. A subnet mask “masks out”
the network bits of the IP address by setting the bits in the mask to 1 when the
network treats the corresponding bits in the IP address as part of the network or
subnetwork address, or to 0 if the corresponding bit identifies the host. The
default subnet mask uses the first two portions of the IP address to identify the
network id, leaving the rest of the IP address to identify specific nodes. To enter a
new subnet mask, highlight the field and enter a new value using dotted decimal
notation (4 decimal values between 1 and 255 separated by periods) as follows:
255.255.255.255
(The Subnet Mask field defaults to the natural mask value, based on the IP
Address that you entered for the device.)
Default Gateway
Contains the IP Address of the device to which all packets addressed to an
unknown network or host are sent. If you do not configure a Default Gateway,
any packets that are addressed to an unknown network or host will be dropped.
This field is not defined until you enter an appropriate value using dotted
decimal notation (4 decimal values between 1 and 255 separated by periods).

Default Interface (Toggle)
Contains the number that represents the interface that is connected to the
module’s Default Gateway. In some instances, dissimilar modules have different
corresponding interface numbers. For example, if you are assigning a default
interface to a 9E133-36 module and you enter a 3, then the default interface is the
Flexible Network Bus. However, if you are assigning a default interface to a
9F310-02 module and you enter a 3, then the default interface is the Internal
Network Bus. See Table 1 for module-specific interface information. The default
is NONE, meaning no default interface selected.
Base MAC Address
Displays the MAC Address of the selected module. This is the MAC Address of
the SMB-10 interface.
TFTP Gateway IP
The IP address of the router that connects to or is closest to the module. Configure
this address when you are performing TFTP downloads in a routed environment
(if proxy ARP is disabled on the router).
The Default Interface field becomes active after you enter an IP address in the
Default Gateway field.

Switch Configuration Screen Fields
The following information briefly explains each Switch Configuration Screen
field.
Bridge Address
Displays the MAC Address of the bridge.
Bridge Priority Label
Allows you to enter a hexadecimal number that identifies the write-able portion
of the Bridge ID, i.e., the first two octets of the Bridge ID. Valid bridge priority
labels range from 0000 to FFFF.
Bridge Path Cost
Allows you to enter (as a hexadecimal number) the cost of the path to the root as
seen from the specified bridge. Valid bridge path costs range from 00000001 to
0FFFFFFF.
Bridging Interfaces
Displays the total number of bridging interfaces on the selected module.
Type of STA (Toggle)
Allows you to set the method that bridges use to decide which bridge is the
controlling (Root) bridge when two or more bridges exist in parallel (Spanning
Tree Algorithm). Valid entries include IEEE and NONE. Press the Space Bar to
toggle to the desired value.
Novell Xlat (Toggle)
Specifies the type of address swapping for Novell translation. Novell Xlat is one
of the following:
• NONE - Address swapping is disabled
• DLC - Bit reversal of the datalink destination address and source address
• LLC - Bit reversal of Netware payload-based MAC addresses
Press the Space Bar to toggle to the desired value. You must SAVE your choice for
it to affect Novell translation.
Interface
Lists each bridge interface on the selected module: FNB, TR1, and TR2.
All bridges in a network must use the same Spanning Tree protocol. The IEEE
protocol has a unique format for its Bridge Protocol Data Units (BPDU). Trying
to mix STA protocols results in an unstable network.
