Current Oper. Mode (Read-only)
This field displays the current operating mode of slots 5 and 6. Depending
on whether a 100BASE-FX or 100BASE-TX Fast Ethernet Interface
Module is installed, this field displays the following:
• With a 100BASE-FX interface: 100Base-FX, 100Base-FXFD (full
duplex), or N/A when the slot is empty.
• With a 100BASE-TX interface: Unknown, 10Base-T, 10Base-TFD
(full duplex), 100Base-TX, 100Base-TXFD (full duplex), or N/A
when the slot is empty.
Desired Oper. Mode (Selectable)
This field allows the user to select the desired operational mode for an
interface in slot 5 or 6. The field toggles between 100Base-FX and
100Base-FXFD (full duplex) when an FE-100FX or FE-100F3 is

automatically establishes a link with the device at the other end
of the segment without requiring user setup. However, Local
Management provides the user with the option of manually
configuring that port.
If an FE-100TX is installed, the field steps to Auto-Negotiation,
10Base-T, 10Base-TFD (full duplex), 100Base-TX, and 100Base-TXFD
(full duplex). In normal operation, the port with an FE-100TX installed is
capable of auto-negotiating the operational mode and no further user
setup is required.
FE-100TX.
In Auto-Negotiation, the FE-100TX negotiates to the highest common
denominator of the two interfaces. The order of priority of negotiation is
100Base-TXFD, 100Base-TX, 10Base-TFD, and 10Base-T.
