Secondly whenever i changing the mapping using configure dot1p type command .. which ever priority i give to qp4,qp5,qp6 the same problem is there.. i mean for example if i assign priority 1 to qp4 then if i intend to pause priority 1 the priorities assigned to qp5, qp6 regardless of their value are also paused. so its not the priority i think its the QOS profile that has a bug. because any priority value assigned to QP4,qp5, qp6, shows the same problem.. what do u think?
