Information

Introduction

This appendix contains local management information that is speciﬁc to the

9E132-15, 9E133-36, 9E138-12, and 9E138-36 MicroLAN modules.

Module Interfaces

The Default Interface ﬁeld on the General Conﬁguration Screen allows you to

enter a number (1 through 6). Each number represents a default interface for the

selected module. Table 1 lists the numbers you can enter, each number’s

corresponding interface, and a brief description of that interface. The default for

this ﬁeld is NONE, meaning no default interface selected.

FNB Resource Conﬁguration Codes

The MicroLAN Modules described in this appendix provide connectivity

between four interfaces: the three front panel Ethernet interfaces and the FDDI

rings on the backplane (FNB-1 or FNB-2).

The front panel of the MicroLAN Modules described in this appendix contain

three Ethernet connections that interface to the Repeater Interface Controllers

(RICs). These function as individual repeating networks; each front panel port

group (ENET1, ENET2, ENET3) is a separate collision domain. Front panel

Ethernet packets are received via the RICs. Bridging/Routing may occur between

these RICs and/or to any other SmartSwitch 9000 module via the Flexible

Network Bus.

The FNB Resource Conﬁguration Screen allows you to connect the module’s front

panel Ethernet interfaces 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.

Connections Description

1 NORING <-> ENET

Neither the FNB-1 nor the FNB-2

on the chassis’ backplane is

connected to the module’s

bridge/switch.

2 FNB1 <-> ENET

The FNB-1 on the chassis’

backplane and the module’s

Ethernet interface(s) are

connected to the same

bridge/switch.

3 FNB2 <-> ENET

The FNB-2 on the chassis’

backplane and the module’s

Ethernet interface(s) are

connected to the same

bridge/switch.

Module Speciﬁc Statistics Screen

Figure 1 displays a variety of information about the selected module including,

bytes received, frames received, total errors, collisions, OOW collisions, CRC

errors, alignment errors, undersize packets, oversize packets, broadcasts,

multicasts, port administration status and port segment status.

MicroLAN Module Speciﬁc Statistics Screen Fields

NETWORK

Displays the code name of the selected network. The four possible values are

FNB, ENET 1, ENET 2, and ENET 3.

PORT

Displays the number of the selected port. (A speciﬁc port may be selected, for

example, ENET 1, ENET 2, or ENET 3.)

BYTES RECEIVED

Displays the number of bytes received.

FRAMES RECEIVED

Displays the number of frames received.

TOTAL ERRORS

Displays the total number of errors received.

COLLISIONS

Displays the number of collisions received.

OOW COLLISIONS

Displays the number of Out Of Window collisions. OOW collisions are usually

caused by the network being too long where the round trip propagation delay is

greater than 51.2

sec. (the collision domain is too large), a station somewhere on

the network is violating Carrier Sense and transmitting at will, or a cable

somewhere on the network failed during the transmission of the packet.

CRC 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 transmitted data that is received is the same as the data that

was originally sent.

ALIGNMENT ERRORS

Displays the number of errors 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.

9E132-15 / 9E133-36 / 9E138-12 / 9E138-36 Module Speciﬁc Information

BROADCASTS

Displays the number of broadcasts received.

MULTICASTS

Displays the number of multicasts received.

PORT ADMIN STATUS

Displays the administrative status of a selected port.

PORT SEG STATUS

Displays the segmentation status of the port selected. The two possible status

messages are Segmented or Unsegmented. The SmartSwitch 9000 automatically

partitions problem segments, and reconnects non-problem segments to the

network.

Choosing a Network

The

NETWORK

command allows you to choose a particular network for which

you want to view module statistics. The choices are FNB, ENET1, ENET2, and

ENET3.

To select a particular network:

1. Use the arrow keys to highlight

NETWORK

2. Press the

Shift

and plus (

) keys until your desired network appears.

3. Press the

Return

key.

Exiting the Module Speciﬁc Statistics Screen

The

RETURN

command allows you to exit the Module Speciﬁc Statistics Screen.

To exit the Module Speciﬁc Statistics Screen:

1. Use the arrow keys to highlight

RETURN

2. Press the

Return

key.

Selecting a Module Port

The

PORT

command allows you to choose a particular module port for which

you want to view port-level statistics.

To select a particular port:

1. Use the arrow keys to highlight

PORT

2. Press the

Shift

and plus (

) keys, or press the minus (

) key, until the desired

port number appears.

3. Press the

Return

key.

Enabling or Disabling a Port

The

ENABLE

PORT

command allows you to enable the port that is identified in

the PORT field; the

DISABLE

PORT

command allows you to disable the port

that is identified in the PORT field. A port must be selected before it can be

enabled or disabled.

To enable or disable a selected port:

1. Use the arrow keys to highlight

ENABLE PORT

DISABLE

PORT

2. Press the

Return

key.

This command appears only when the selected network is Ethernet (ENET1,

ENET2, or ENET3). You can NEVER enable or disable an FNB port.

NOTE

These commands appear only when the selected network is Ethernet (ENET1,

ENET2, or ENET3). You can NEVER enable or disable an FNB port.
