9T125-08 Module Specific Information
FNB Resource Configuration Codes
The 9T125-08 Module provides connectivity between one of 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.
Neither the FNB-1 nor the FNB-2 on
the chassis’ backplane is connected to
the module’s bridge/switch.
The FNB-1 on the chassis’ backplane
and the module’s front panel Token
Ring interfaces are connected to the
same bridge/switch.
The FNB-2 on the chassis’ backplane
and the module’s front panel Token
Ring interfaces are connected to the
same bridge/switch.

General Configuration Screen
The General Configuration Screen (Figure 1), displays various information about
the selected module and allows you to set the following general parameters:
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).
NOTE
Module Time
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.
The module’s default date and time settings are indeterminate. The internal
calendar and clock begin running as soon as you install the module.
Screen Refresh Time
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.

Page 7
9T125-08 Module Specific Information
Screen Lockout Time
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).

Page 8
9T125-08 Module Specific Information
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.
The Default Interface field becomes active after you enter an IP address in the
NOTE
Default Gateway field.
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).

Token Ring Secured Station Configuration
The Token Ring Secured Station Configuration Screen (Figure 7), allows you to
control access to the module’s token ring network.
The Disabled mode (by default) allows all new stations to enter the ring.
When ring security is enabled in Alarm Only mode, the module stores the MAC
address of each station on the token ring network in a secure database or
“allowed list.” The module can store up to 250 station MAC addresses on the
allowed list. The module retains the allowed list in its battery-backed NonVolatile Random Access Memory (NVRAM). When the module is powered up or
reset, all MAC addresses are retained and ring security is reenabled automatically.
The Alarm Only mode allows new stations to enter the ring, but a “station added”
trap/alarm notifies the Network Management Station (NMS) of the event. The
trap/alarm includes the new station’s MAC address so that the network manager
can decide if the new station should be allowed on the ring.
!
CAUTION
Do not enter Remove/Alarm mode without first entering the Alarm Only mode
or adding nodes to the allowed list. All nodes not appearing in the list, currently
active on the ring, WILL BE REMOVED!
The Remove/Alarm mode sends a “Remove Station MAC Frame Command” to
new stations attempting to enter the ring, and a trap/alarm to the NMS informing
it of the action taken. If, after three attempts, the station (outside the hub) cannot
be removed from the ring, a trap/alarm is sent to the NMS informing it that “the
station could not be removed.” Also, the port is disabled for the station directly
connected to the hub and a trap/alarm is sent indicating port removal.
To access the Token Ring Secured Station Configuration Screen from the Module
Specific Configuration Menu:
1. Use the arrow keys to highlight the Token Ring Security option.
2. Press the Enter key.
The Token Ring Secured Station Configuration Screen (Figure 7), appears.

22
Page 25
9T125-08 Module Specific Information
4. Press the Space Bar until the command toggles to display DEL.
5. Press the Return key.
The station appears in the Station Address list.
Security Mode (Toggle)
Allows you to set one of three security modes for the module’s token ring.
!
CAUTION
Make sure you understand the consequences of changing security modes.
Each mode offers more security than the previous mode. Select from the
following modes:
•Disabled (default) - Use this mode to temporarily disable ring security so that
new stations can enter the ring.
•Alarm Only - In this mode, new stations can enter the ring and are added to
the allowed list, but a “Station Added” trap/alarm is sent to the Network
Management Station. This trap message is only sent once, and it includes the
new station’s MAC address so that the network manager can decide if the new
station should be allowed on the ring.
When temporarily disabling ring security to allow new users to enter the ring,
use the Alarm Only mode to reenable ring security. In Alarm Only mode, the
management module stores the MAC address of each station on the ring in
the allowed list. This eliminates entering MAC addresses one at a time using
the Stn Edit field.
•Remove/Alarm - This is the highest level of ring security. In this security mode,
the ring is locked to new stations. The Remove/Alarm mode sends a “Remove
MAC Frame” command to a new station attempting to enter the ring, and a
trap/alarm to the NMS informing it of the action taken. If, after three attempts,
the station cannot be removed from the ring, remove alarm sends a trap/alarm
“Remove Failure” to the NMS, informing it that the station could not be
removed.
If you change directly from Disabled mode to Remove/Alarm mode, all stations
NOTE
that have not been added to the allowed list will be removed from the token ring.

Frames Received
Displays the number of frames received on the token ring.
Kbytes T ransmitted
Displays the number of kilobytes transmitted on the token ring.
Kbytes Received
Displays the number of kilobytes received on the token ring.
Beacon States
Displays the number of times that a beacon even occurred on the token ring.
Ring Purges
Displays the number of times that an Active Monitor on the token ring generated
a ring purge MAC frame to clear ring problems.
Ring Number
Identifies the source route ring number (a hexadecimal value) assigned to this
ring.
Ring Status
Displays the current condition of the token ring. Valid conditions include
Unknown, Closed, Normal, Purge, Contention, and Beaconing.

Burst Errors
Displays the number of times a signal is not received by a station on the token
ring.
AC Errors
Displays the number of times that two successive AMP or SMP frames are
received with A and C bits set at zero.
Abort Transmit Errors
Displays the number of times that a station transmits an abort delimiter while
transmitting.
Internal Errors
Displays the number of times that a station encounters a recoverable internal
error. This information helps to detect a station in marginal operating condition.
NON-ISOLATING ERRORS
Lost Frame Errors
Displays the number of times that a station’s TRR timer expires before the station
receives the ending delimiter of the frame transmitted.

Frame Copied Errors
Displays the number of times that a node receives a frame with its address as the
destination address, however the Address Recognized bit is already set to ‘1’.
Rcvr Congestion Errors
Displays the number of times that a station on the token ring recognizes its
address, but it cannot copy the frame because the buffer is full.
Token Errors
Displays the number of times that a token on the token ring has encountered a
problem along its path.
Frequency Errors
Displays the number of times that the frequency of an incoming signal differs by
more than 0.6% from the local oscillator.
Token Ring LAN Statistics Screen Commands
TOTAL / ACCUMULATE / DELTA (Toggle)
Allows you to:
•Display a running TOTAL of statistics (statistics since the module was inserted
into the chassis).
•Reset the statistics to zero and then ACCUMULATE and display figures from
that point in time forward.
•Display statistics and then reset the statistics to zero each time the screen is
refreshed (DELTA).
Table 6 shows the various statistics after four screen refreshes:

TOKEN RING 1/TOKEN RING 2 (Toggle)
Allows you to select the interface for which statistics are displayed.
•If you select TOKEN RING 1, token ring statistics for the module’s number one
interface are displayed.
•If you select TOKEN RING 2, token ring statistics for the module’s number two
interface are displayed.
Press the SpaceBar to toggle to the desired value, then press the Return key.
REFRESH (Toggle)
Allows you to select the interval at which the screen will be updated (the range is
3 - 99 seconds). To increase the number of seconds, press the SpaceBar while the
cursor is on the command. To decrease the number of seconds, press the BackSpace key while the cursor is on the command.
CLEAR
A command that only appears when you select ACCUMULATE as a statistic
reporting method. The CLEAR command allows you to manually reset the
screen’s statistics to zero and then start to accumulate statistics from that point in
time. For example, you may have accumulated statistics for 45 minutes, but now
you want to see accumulated statistics for the current period. In this case you
would position the cursor onto the CLEAR command and press the Space Bar.
The screen’s statistics will reset to zero and start to accumulate again.
RETURN
Allows you to exit the 9T125-08 Token Ring LAN Statistics Screen.
