Configure output scheduling on the Catalyst 6500 with PFC1 or PFC2 and Catalyst OS system software

[TCC_2]

Resolution

Output scheduling is used to ensure that important traffic does not get dropped in the event of heavy over-subscription. Quality of Service (QOS) has different stages of operation and implementation. Output scheduling is applied on the interface after shaping and policing.

For more information on understanding and configuring output scheduling on Catalyst 6000 switches, refer to QoS on Catalyst 6000 Family Switches: Output Scheduling on the Catalyst 6000 with PFC or PFC 2 Using Hybrid Mode.

The document discusses these topics:

• Types of queueing involved in output scheduling on the Catalyst 6000
• Output queueing capability of different line cards on the Catalyst 6000
• Configuration, monitoring, and output scheduling on the Catalyst 6000
• Using output scheduling to reduce delay and jitter
