HAL.Port.FabFlowCtrlUnsuprt

Description

A Priority Flow Control configuration is applied to a stack that includes a Summit X670 or X670V which does not support fabric flow control messages on alternate stack ports or V80 native stack ports. These fabric flow control messages are required to provide priority flow control between ports on different slots in the stack. PFC between ports within the same slot will operate as expected.

Remedy

This is a hardware limitation on the X670 when using alternate stack ports or V80 native stack ports. PFC between ports on the same slot is not affected by this limitation. Stacking with V160 native stack ports supports fabric flow control messages and is the recommended stacking configuration for X670V if PFC is required between ports on different slots.
