Command History
Usage Guidelines
The
negotiation
command is applicable only to the Gigabit Ethernet interface of the
Cisco 7200-I/O-GE+E. The
negotiation auto
command is used instead of the
duplex
and
speed
commands (which are used on Ethernet and Fast Ethernet interfaces) to automatically configure the
duplex and speed settings of the interfaces. The
negotiation forced
command is used to configure the
Gigabit Ethernet interface to be 1000/full-duplex only and to disable flow-control. The Gigabit Ethernet
interface of the Cisco 7200-I/O-GE+E is restricted to 1000 Mbps/full duplex only. Autonegotiation only
negotiates to these values.
Examples
The following example configures the Gigabit Ethernet interface of the Cisco 7200-I/O-GE +E to auto
negotiate:
configure terminal
interface gigabitethernet 0/0
negotiation auto
Related Commands
