Scheduling Modes

The scheduler modes available on adapter cards are 4-priority and 16-priority. Which modes are supported on a particular adapter card depends on whether the adapter card is a second-generation or third-generation card.

Note: Throughout the 7705 SAR documentation set, second-generation and third-generation Ethernet adapter cards and Ethernet ports on fixed platforms are also referred to as Gen-2 and Gen-3 hardware.

On Gen-3 hardware, 4-priority scheduling mode is the implicit, default scheduling mode and is not user-configurable. Gen-3 platforms with a TDM block support 4-priority scheduling mode. Gen-2 adapter cards support 16-priority and 4-priority scheduling modes.

For more information on differences between Gen-2 and Gen-3 hardware related to scheduling mode QoS behavior, see QoS for Gen-3 Adapter Cards and Platforms.
