Managing the Module 2-43
The Device View
For a 100Base-FX port, the selection process is somewhat simpler; Auto-Negotiation for
these ports is not supported at this time, so you need only choose between 100Base-FX
standard mode and 100Base-FX Full Duplex. However, you must still be sure that both
link partners are set to the same operational mode, or the link will be unstable.
To set your desired operational mode:
1. Click on the Desired Operational Mode list box to display the menu of
available options; click to select the operational mode you wish to set.
For 100Base-TX ports, the available options are:
Auto Negotiation — the operational mode will be dynamically set based on
the modes selected in the Advertised Abilities field (where both link partners
are auto-negotiating) and the speeds and modes supported by the attached
device
10Base-T — 10 Mbps connection, Standard Mode
10Base-T Full Duplex — 10 Mbps connection, Duplex Mode
100Base-TX — 100 Mbps connection, Standard Mode
100Base-TX Full Duplex — 100 Mbps connection, Duplex Mode
For 100Base-FX ports, options are:
100Base-FX — 100 Mbps connection, Standard Mode
100Base-FX Full Duplex — 100 Mbps connection, Duplex Mode
2. If you have selected Auto-Negotiation (for 100Base-TX ports only), use the
Advertised Abilities field to select the operational capabilities you wish to
advertise to the port’s link partner. If both link partners will be auto-negotiating,
be sure there is at least one mutually-advertised operational mode, or no link
will be achieved.
TIP
If you select Auto-Negotiation at both ends of a link, be sure at least one
mutually-advertised operational mode is available.
TIP
The selected Advertised Abilities only come into play when both link partners are
auto-negotiating; if only one link partner is set to auto-negotiate, that node will establish
a link at whatever mode its partner is set to, even if that mode is not currently being
advertised.
