Shaping Input and Output Traffic on Ethernet IQ2 Interfaces

Gigabit Ethernet Intelligent Queuing 2 (IQ2) 4-port and 8-port Type 2 Physical Interface Cards (PICs) are oversubscribed, which means the amount of traffic coming to the PIC can be more than the maximum bandwidth from the PIC to the Flexible PIC Concentrator (FPC).

This chapter discusses the following topics:

• Configuring Shaping on Ethernet IQ2 Interfaces
• Differences Between Gigabit Ethernet IQ and Gigabit Ethernet IQ2 PICs
• Configuring a Shared Scheduler and Shaper
• Differences Between Per-Unit Scheduling and Shared Scheduling
• Configuring Separate Input Schedulers
• Configuring Hierarchical Input Shapers
• Examples: Shaping Input and Output Traffic on Ethernet IQ2 Interfaces
