on priority, which has the same principle as flow control this series of switches use pfc to achieve the purpose of flow control, support global enable/de enable pfc and specify one or some queues enable/de enable pfc this series of products supports setting up to two lossless queues the default lossless queues are 3 and 4, so pfc is enabled by default for queue 3 and 4 queues o 0 7 (sub
