Speed and Duplex Mode Configuration Guidelines
You usually configure Ethernet port speed and duplex mode parameters to auto and allow the
Catalyst 6500 series switch to negotiate the speed and duplex mode between ports. If you decide to
configure the port speed and duplex modes manually, consider the following information:
•
•
•
•
Catalyst 6500 series switches cannot automatically negotiate Ethernet port speed and duplex mode if the
Note
connecting port is configured to a value other than auto.
Caution
Changing the Ethernet port speed and duplex mode configuration might shut down and reenable the
interface during the reconfiguration.

If you set the Ethernet port speed to auto, the switch automatically sets the duplex mode to auto.
If you enter the no speed command, the switch automatically configures both speed and duplex to
auto.
If you configure an Ethernet port speed to a value other than auto (for example, 10, 100, or
1000 Mbps), configure the connecting port to match. Do not configure the connecting port to
negotiate the speed.
If you manually configure the Ethernet port speed to either 10 or 100 Mbps, the switch prompts you
to also configure the duplex mode on the port.
