Setting Auto-Negotiation and Advertised Ability
Purpose
To review, disable or enable auto‐negotiation, and to configure port advertisement for speed and
duplex.
During auto‐negotiation, the port “tells” the device at the other end of the segment what its
capabilities and mode of operation are. If auto‐negotiation is disabled, the port reverts to the
values specified by default speed, default duplex, and the port flow control commands.
In normal operation, with all capabilities enabled, advertised ability enables a port to “advertise”
that it has the ability to operate in any mode. The user may choose to configure a port so that only
a portion of its capabilities are advertised and the others are disabled.
Refer to “ Configuring SFP Ports for 100BASE‐FX ” on page 4‐2 for information on configuring
settings for 100 Mb SFP ports.
Commands
