How many ingress and egress queues are there per port on the Cisco 2960-X switches?

see table-2 in this link:

Thanks Reza
Table 2 list 4 output/egress queues. But no mention of ingress queue/s
Below shows the output of a 'sh interface' of a particular port
Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 0
Queueing strategy: fifo
Output queue: 0/40 (size/max)
1. Based on the above output can I safely assume that there is 1 input/ingress queue?
2. Why is the size of both input and output queue 0?
3. For the output queue, is the max of 40 a reflection of all four queues?
4. Why is the Queuing strategy saying

Hi,
It seems that the only way you can configure ingress queues on the 2960-x series switches is by using auto-qos. See table-2 in this link:

Thanks for your response Reza, but based on the link below, ingress queuing and scheduling is not supported on the 2960-x switches. See note under section "Actions at Ingress Port"

With respect to egress queuing, there are four (4) outbound queues.
