4.3.6 Setting Auto-Negotiation and Advertised Ability
Purpose
To review, disable or enable auto-negotiation, and to review or set a port’s advertised mode of
operation.
During auto-negotiation and advertised ability, 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.
Commands
The commands used to review and configure auto-negotiation and advertised ability are listed
below and described in the associated section as shown.
• show port negotiation (Section 4.3.6.1)
• set port negotiation (Section 4.3.6.2)

NOTE: Advertised ability can be activated only on ports that have auto-negotiation
enabled.
