9T122-08 Module Specific Information  
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).  
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.  
NOTE  
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 default  
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  
is NONE, meaning no default interface selected.  
The Default Interface Þeld becomes active after you enter an IP address in the  
Default Gateway Þeld.  
NOTE  
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).

9T122-08 Module Specific Information  
Token Ring Secured Station Configuration  
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 Non-  
Volatile 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.  
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!  
!
CAUTION  
The Remove/Alarm mode sends a ÒRemove Station MAC Frame CommandÓ to

Security Mode (Toggle)  
Allows you to set one of three security modes for the moduleÕs token ring.  
Make sure you understand the consequences of changing security modes.  
!
CAUTION  
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  
 
9T122-08 Module Specific Information  
¥
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  
that have not been added to the allowed list will be removed from the token ring.  
NOTE  
Selecting a Security Mode  
To select a Security Mode:  
1. Use the arrow keys to highlight the Security Mode Þeld.  
2. Press the Space Bar to toggle to the desired security mode (either Disabled,  
Alarm Only, or Remove/Alarm).  
3. Use the arrow keys to highlight the SAVE/EXECUTE command, then press  
the Return key. The selected mode of ring security becomes effective.  
Viewing Previous/Next Page of Station Addresses  
To view the previous/next page (if there is one) of station addresses, use the  
arrow keys to highlight the appropriate range of station addresses command (for  
example, [ 9-16 ]), then press the Return key.  
Exiting the Token Ring Secured Station Configuration Screen  
To exit the Token Ring Secured Station ConÞguration Screen, use the arrow keys  
to highlight RETURN, then press the Return key.
