This command forces two connected ports into a master/slave configuration to
enable 1000BASE-T full duplex for Gigabit ports. Use the no form to restore the
default mode.

Command Usage
◆
The 1000BASE-T standard does not support forced mode. Auto-negotiation
should always be used to establish a connection over any 1000BASE-T port or
trunk. If not used, the success of the link process cannot be guaranteed when
connecting to other types of switches. However, this switch does provide a
means of forcing a link to operate at 1000 Mbps, full-duplex using the giga-
phy-mode command.
◆
To force 1000full operation requires the ports at both ends of a link to establish
their role in the connection process as a master or slave. Before using this
feature, auto-negotiation must first be disabled, and the Speed/Duplex
attribute set to 1000full. Then select compatible Giga PHY modes at both ends
of the link.
