The Device View
The window displays the following information about the selected Fast Ethernet port:
Port Type
Displays the port’s type: 100Base-TX RJ-45 (for built-in Fast Ethernet ports and the
FE-100TX Fast Ethernet port module), 100Base-FX MMF SC Connector (for the
FE-100FX Fast Ethernet port module), or Unknown (for a port slot with no module
installed).
Link State
Displays the current connection status of the selected port: Link or No Link.
Current Operational Mode
Indicates which of the available operational modes is currently in effect: 10Base-T,
10Base-T Full Duplex, 100Base-TX, 100Base-TX Full Duplex, 100Base-FX, or
100Base-FX Full Duplex. If the port is still initializing, not linked, or if there is no port
module installed in the slot, this field will remain blank.
Desired Operational Mode
Displays the operational mode that you have selected for this port, and allows you to
change that selection. The following operational modes are available for each port:
100Base-TX
Auto-Negotiation, 10Base-T, 10BASE-T Full Duplex, 100Base-TX,
and 100Base-TX Full Duplex.
100Base-FX
100Base-FX and 100Base-FX Full Duplex
Note that if Auto-Negotiation is the selected mode, the Current Operational Mode field
will indicate which mode was selected by the link partner.

Advertised Abilities
For 100Base-TX ports which have been configured to operate in Auto-Negotiation mode,
this field allows you to select which of the operational modes available to the port can be
selected by the negotiating link partners.
!
CAUTION
If you choose to select a specific mode of operation (rather than auto-negotiation), you
should be sure that the link partner supports the same mode. Otherwise, no link will be
achieved.
If you select a Full Duplex mode and the link partner supports the same wire speed but not
Full Duplex, a link will be achieved, but it will be unstable and will behave erratically.
If you select Auto-Negotiation, the local node will try to match the mode of the link
partner, even if the link partner is not set to auto-negotiate, and even if the local node must
use a mode which it is not currently advertising.
