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:

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.

9
9H423-28 Module Specific Information
MULTICASTS
Displays the number of multicasts received.
LINK STATUS
Indicates whether there is a physical connection from this port to another device.
One of the following values appears:
• Link - There is a link signal present; there is a valid physical connection from
this port to another device.
• No Link - There is no link signal present; there is no valid physical connection
from this port to another device.
PORTTYPE
Displays one of the following values:
• AUI
• BNC
• EPIM-x
• FE-xx
• MMF SMA
• MMF SC
• RJ45
• RJ71
• SMF ST
PORT STATUS
Indicates the administrative status of the selected port. Possible values are:
• ENABLED - The port is turned on administratively
• DISABLED - The port is turned off administratively
APPLICATION
Displays BRIDGING , indicating that the port is operating as a bridge with a
high-speed backbone connection.
OPERATION MODE
Displays the value FULL DUPLEX . The port can transmit and receive data at the
same time.
Enable or disable ports from the Bridge Configuration screen.
