9T125-24 Module Speciﬁc Information

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.

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.

9T125-24 Module Speciﬁc Information

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).

9T125-24 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.

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.

NOTE

9T125-24 Module Speciﬁc Information

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.
