speed-duplex

C U
OMMAND SAGE
This command allows you to disable a port due to abnormal behavior
(e.g., excessive collisions), and then re-enable it after the problem has
been resolved. You may also want to disable a port for security reasons.
E
XAMPLE
The following example disables port 5.
Console(config)#interface ethernet 1/5
Console(config-if)#shutdown
Console(config-if)#
This command configures the speed and duplex mode of a given interface
when auto-negotiation is disabled. Use the no form to restore the default.

no speed-duplex
1000full - Forces 1000 Mbps full-duplex operation
100full - Forces 100 Mbps full-duplex operation
100half - Forces 100 Mbps half-duplex operation
10full - Forces 10 Mbps full-duplex operation
10half - Forces 10 Mbps half-duplex operation

EFAULT ETTING
Auto-negotiation is enabled by default.
When auto-negotiation is disabled, the default speed-duplex setting is:
Fast Ethernet ports – 100full for 100BASE-TX ports
Gigabit Ethernet ports – 100full for 1000BASE-T ports

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.
To force operation to the speed and duplex mode specified in a speed-
duplex command, use the
negotiation on the selected interface.
When using the negotiation
optimal settings will be determined by the
