General Configuration Screen Fields
The following information brießy explains each General ConÞguration Screen
Þeld.
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 ßash 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 Þeld 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 Þrst eight digits you
enter in this Þeld 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 Þeld 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 Þrst six digits you enter in
this Þeld represent an entry (i.e., 160700). For 6:12 a.m., enter 6:12:00 or 061200.
The moduleÕs 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 moduleÕs screens are updated. This setting
determines how frequently (in seconds) information is updated on the screen. To
enter a new refresh rate, highlight the Þeld and enter a number. The
refresh rate is 3 seconds. The
range is 3 - 99 seconds.

9T122-08 Module Specific Information
Screen Lockout Time
Contains the maximum number of minutes that the Local Management
application will display a moduleÕs screen while pending input or action from a
user. For example, if you enter 5 in this Þeld, users will have up to Þve minutes to
respond in some fashion to each of the speciÞed moduleÕs Local Management
screens. In our example, after Þve minutes of ÒidlenessÓ (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
Þeld 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 Þeld according to your network requirements. Highlight the Host IP
Address Þeld 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 Òmasks outÓ
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 identiÞes the host. The
default subnet mask uses the Þrst two portions of the IP address to identify the
network id, leaving the rest of the IP address to identify speciÞc nodes. To enter a
new subnet mask, highlight the Þeld 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 Þeld 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 conÞgure a Default Gateway,
any packets that are addressed to an unknown network or host will be dropped.
This Þeld is not deÞned until you enter an appropriate value using dotted
decimal notation (4 decimal values between 1 and 255 separated by periods).
5
9T122-08 Module Specific Information
Default Interface (Toggle)
Contains the number that represents the interface that is connected to the
moduleÕs Default Gateway. In some instances, dissimilar modules have different
corresponding interface numbers. For example, if you are assigning a default
interface to a 9T122-08 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-speciÞc interface information. The
is NONE, meaning no default interface selected.
The Default Interface Þeld becomes active after you enter an IP address in the
NOTE
Default Gateway Þeld.
default
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. ConÞgure
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 9T122-08 Token Ring Secured Station ConÞguration Screen (Figure 8), allows
you to control access to the moduleÕs 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
Òallowed list.Ó 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 Òstation addedÓ
trap/alarm notiÞes the Network Management Station (NMS) of the event. The
trap/alarm includes the new stationÕs 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 Þrst 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 ÒRemove Station MAC Frame CommandÓ 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 Òthe
station could not be removed.Ó 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 9T122-08 Token Ring Secured Station ConÞguration Screen from the

Security Mode (Toggle)
Allows you to set one of three security modes for the moduleÕs 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 - This is the default setting. 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 ÒStation AddedÓ trap/alarm is sent to the Network
Management Station. This trap message is only sent once, and it includes the
new stationÕs 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 Þeld.
24
¥ 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 ÒRemove
MAC FrameÓ 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
ÒRemove FailureÓ 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.
Selecting a Security Mode
To select a Security Mode:
1. Use the arrow keys to highlight the Security Mode Þeld.
