Setting Port Auto-Negotiation and Advertised Ability
Purpose
To determine whether auto-negotiation is enabled or disabled for the specific port and to set the
state, and to display 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.
