Feature Overview
The Cisco 7200-I/O-GE+E is an Input/Output controller that provides one Gigabit Ethernet and one
Ethernet port. It is equipped with a GBIC receptacle for 1000 megabits per second (Mbps) operation
and an RJ-45 receptacle for 10 Mbps operation.
The Cisco 7200-I/O-2FE/E is an Input/Output controller that provides two autosensing Fast Ethernet
ports and is equipped with two RJ-45 receptacles for 10/100 Mbps operation.
I/O controllers support the following features:
•Dual EIA/TIA-232 channels for local console and auxiliary ports
•NVRAM for storing the system configuration and environmental monitoring logs
•Two PC Card slots that hold Flash disks or Flash memory cards for storing the default Cisco IOS
software image
•Flash memory for storing the boot helper image
•Two environmental sensors for monitoring the cooling air as it enters and leaves the chassis

negotiation
On the Gigabit Ethernet port of the Cisco 7200-I/O-GE+E to configure speed, duplex, and flow control,
use the negotiation {forced | auto} interface configuration command. Use the no negotiation auto
command to disable automatic negotiation.
negotiation {forced | auto}
Syntax Description
Defaults Negotiation auto
Command Modes Interface configuration
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
