no speed-duplex
1000full - Forces 1 Gbps 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

◆
Auto-negotiation is enabled by default on the Gigabit ports, and
disabled on the 10 Gigabit ports.
◆
When auto-negotiation is disabled, the default speed-duplex setting is
100full on the 1000Base-T ports, 1000full on the 1000Base SFP ports,
and 10Gfull on the 10G ports.
◆
The speed-duplex setting on the 10G ports is fixed at 10Gfull.

◆
The 1000BASE-T and 10GBASE-T standard does not support forced
mode. Auto-negotiation should always be used to establish a
connection over any 1000BASE-T and 10GBASE-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
no
command to disable auto-
negotiation on the selected interface.
◆
When using the
command to enable auto-negotiation, the
optimal settings will be determined by the
command. To set
the speed/duplex mode under auto-negotiation, the required mode
must be specified in the capabilities list for an interface.

The following example configures port 5 to 100 Mbps, half-duplex
operation.
Console(config)#interface ethernet 1/5
Console(config-if)#speed-duplex 100half
Console(config-if)#no negotiation
Console(config-if)#
