F2 linecard QoS scheduling

Hi, working on an N7K with F2 linecards.  All documentation I can find states the F2 cards only have 4 queues and default is 1p3q1t.  However, when I do a show int capabilities on an F2 port, I see the QoS scheduling below, which I am not sure about?

I don't know why it is reporting 8q4t and 3p5q1t when only 4 queues are available in hardware?

N7K1# sh queuing int e3/1

 Egress Queuing for Ethernet3/1 [System]

Template: 4Q8E (2 Ingress Buffers)

  • try to do this 

    show system internal qos queuing config interface ethernet 3/1 | begin COS2Q

    what is the output?

    it should show cos to queue mapping.

  • The CoS to Q mapping is shown here, and clearly shows only 4 queues, which we know from all the data sheets that that is all the F2 cards support.  I'm just wondering why it shows a 3p5q1t template?
