Information

Introduction

This appendix contains local management information that is speciﬁc to the

9G421-02 and 9G429-02 Ethernet Modules.

The 9G421-02 and 9G429-02 modules are 3-port Ethernet switching modules with:

• 2 front-panel gigabit Ethernet ports

• 1 Internal Network Bus (INB) backplane port

Modifying Fields and User Privileges

To modify ﬁelds on this module, you must have read-write or super-user

privileges. If you have read-only privileges, you can view information; however,

you cannot modify any ﬁelds. For more information about user privileges and

community names, see the

SmartSwitch 9000 Module Local Management User’s

Guide.

9G421-02/9G429-02 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

9G421-02/9G429-02 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

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). For example,

255.255.255.255.

The maximum number that you can enter in any of the four segments is 255. The

default

is 0.0.0.0 . Any of the system interfaces on the module can use this

address.

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). For example,

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). The

default

is NONE DEFINED, meaning no default gateway selected.

9G421-02/9G429-02 Module Speciﬁc Information

Default Interface

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 DEFINED, 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).

Exiting the General Conﬁguration Screen

To exit the General Conﬁguration Screen, use the arrow keys to highlight

RETURN, then press the Return key.

The Default Interface ﬁeld becomes active after you enter an IP address in the

Default Gateway ﬁeld.

Displays the total number of errors on the port.

COLLISIONS

Displays the total number of collisions detected on this port.

CRC/ALIGNMENT ERRORS

Displays the number of packets with bad Cyclic Redundancy Checks (CRC) that

have been received from the network. The CRC is a 4-byte ﬁeld in the data packet

that ensures that the data received is the same as the data that was originally sent.

Alignment errors are due to misaligned packets.

UNDERSIZE PACKETS

Displays the number of packets received whose size was less than the minimum

Ethernet frame size of 64 bytes, not including preamble.

OVERSIZE PACKETS

Displays the number of packets received whose size exceeded 1518 data bytes,

not including preamble.

Displays the total number of packets received that were not an integral number of

octets in length or that had a bad Frame Check Sequence (FCS), and were less

than 64 octets in length (excluding framing bits but including FCS octets).

JABBERS

Displays the total number of packets received that were longer than 1518 octets

(excluding framing bits, but including Frame Check Sequence (FCS) octets), and
