Interface Configuration (Ethernet, Port Channel)
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 safely forcing a link to operate at 1000 Mbps, full-duplex
using the giga-phy-mode command (page 4-194).
• To force operation to the speed and duplex mode specified in a speed-duplex
command, use the no negotiation command to disable auto-negotiation on
the selected interface.
• When using the negotiation command to enable auto-negotiation, the
optimal settings will be determined by the capabilities command. To set the
speed/duplex mode under auto-negotiation, the required mode must be
specified in the capabilities list for an interface.
Example
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)#
