Catalyst 2950 series switches do not provide any ingress scheduling, but they do support egress queuing and scheduling. Use the wrr-queue bandwidth command. The default is to use FIFO. The Catalyst 2950 series switches provide QoS-based 802.1p CoS values. In Cisco IOS Software Release 12.0(5)WC1 and later, the 2950 series switches honor the CoS value of an incoming frame by default.
