Port Conﬁguration Screen Fields

The following information brieﬂy explains each Port Conﬁguration Screen ﬁeld.

Port #

Displays the port number of the current 100 Mb Ethernet port.

PortType

Displays one of the following values:

• AUI

• BNC

• EPIM-x

• FE-xx

• MMF SMA

• MMF SC

• RJ45

• RJ71

• SMF ST

Link Status

Displays the status of the Link Integrity pulse for the twisted pair or ﬁber optic

segment. You will see one of the following:

• Link

• No Link

Current Operational Mode

Displays the operational mode that was set using the Desired Operational Mode

ﬁeld.

Buffer Utilization (Toggle)

Allows you to specify how the Receive (Rx) and Transmit (Tx) buffers will be

utilized (on a percentage basis). Valid choices are:

• Auto

• 80/20

• 60/40

• 40/60

• 20/80

9H423-28 Module Speciﬁc Information

Desired Operational Mode (Toggle)

Allows you to specify how you want the port to communicate with a device. If

you specify Auto-Negotiation, the port and the device automatically synchronize

communication. Valid modes are:

• Auto-Negotiation

• 10Base-T

• 10Base-T FD (Full Duplex)

• 100Base-TX

• 100Base-TX FD (Full Duplex)

• 100Base-T4

• 100Base-FX

• 100Base-FX FD (Full Duplex)

Advertised Ability (2Toggles)

Allows you to specify which Operational Modes the port should use (Enabled) or

not use (Disabled) in Auto-Negotiation. By

default

, operational modes are

Enabled

Disabling an Operational Mode for Auto-Negotiation

To disable an Operational Mode for Auto-Negotiation:

1. Make sure the Desired Operational Mode ﬁeld displays

Auto-Negotiation

2. Use the arrow keys to highlight the left toggle ﬁeld.

3. Press the

Space

Bar

to display an Operational Mode you want to disable.

4. Use the arrow keys to highlight the right toggle ﬁeld.

5. Press the Space Bar until

Disabled

is displayed.

The Operational Mode is disabled.

6. To disable another Operational Mode, repeat steps 2 through 5.

Changing to Another Port

To change to another port:

1. Use the arrow keys to highlight the

Port #

ﬁeld at the bottom of the screen.

2. Press the

Space

Bar

to increment (or press the

Backspace

key to decrement)

the port number.

Port Statistics Screen Fields

The following information brieﬂy explains each Port Statistics Screen ﬁeld.

PORT #

Indicates the current port for which statistics are displayed.

OCTETS

Displays the number of octets transmitted and received.

PACKETS

Displays the number of packets transmitted and received.

TOTAL ERRORS

Displays the total number of errors on this 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 transmitted data that is 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.

FRAGMENTS

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

were not an integral number of octets in length or had a bad Frame Check

Sequence.

BROADCASTS

Displays the number of broadcasts received.
