Setting the appropriate duplex mode is done at the interface configuration prompt. The choices you have are Auto, Full, or Half; the default is Auto, so your switch should work in most cases if you do not make any configuration changes at all. Note that if you manually set duplex to Half or Full, the interface(s) will be locked to that setting and will no longer use the Auto negotiation to dynamically determine the duplex setting of the link(s).

Following is an example of a configuration that sets Interface FastEthernet 0/1 to Full duplex/100Mbs, Interface 0/2 to Half Duplex/10Mbs, and Interface 0/3 to Auto Duplex/Auto speed:

2950#config terminal
2950(config)#interface fastethernet 0/1
2950(config-if)#duplex full
2950(config-if)#speed 100
2950(config-if)#interface fastethernet 0/2
2950(config-if)#duplex half
2950(config-if)#speed 10
2950(config-if)#interface fastethernet 0/3
2950(config-if)#duplex auto
2950(config-if)#speed auto

The configuration would be either:
->Half duplex(i.e one way)
->Full duplex(i.e two way)
