Ports
Description User Impact
10GBaseT ports operating at speeds
lower than 10G must have both Flow
Control and Priority Flow Control
enabled in hardware. As a result, when
showing the interface status, Flow
Control will show active on interfaces
enabled for Priority Flow Control.
This is automatically enabled when the user enables Priority Flow
Control.
When using Priority Flow Control, the
dot1p-mapping to traffic class must be
one-to-one. For example, dot1p value 0
must be mapped to traffic class 0, and
dot1p value 1 must be mapped to traffic
class 1.
If this is not done, the wrong queue may be suspended when priority
flow control frames are received.
