Question about a switch port configuration on a Cisco switch

Hello Cisco Experts,

I have been handed the Cisco administration at work.  I'm not a total newbie, but pretty close.  I have been asked to configure a port for a new server.  My regular configuration would look something like this:

interface GigabitEthernet1/29
 description FILESERVER1
 switchport
 switchport access vlan 100
 switchport mode access
 switchport nonegotiate
 speed 1000
 duplex full
 flowcontrol receive on
 flowcontrol send on
 spanning-tree portfast edge
 spanning-tree bpduguard enable

I found a free port on the server and it's configuration is as follows:

interface GigabitEthernet9/11
description UNUSED
switchport
switchport access vlan 60
switchport mode access
switchport nonegotiate
shutdown
priority-queue queue-limit 5
 wrr-queue queue-limit 65 15 15
 wrr-queue random-detect min-threshold 1 70 100 100 100 100 100 100 100
 wrr-queue random-detect min-threshold 2 70 100 100 100 100 100 100 100
 wrr-queue random-detect min-threshold 3 40 40 50 50 60 60 70 70
 wrr-queue random-detect max-threshold 1 100 100 100 100 100 100 100 100
 wrr-queue random-detect max-threshold 2 100 100 100 100 100 100 100 100
 wrr-queue random-detect max-threshold 3 70 70 80 80 90 90 100 100
 wrr-queue cos-map 2 1 1 2
 wrr-queue cos-map 3 5 3 4
 wrr-queue cos-map 3 7 6 7
flowcontrol receive on
flowcontrol send on
spanning-tree bpduguard enable

Can someone tell me what the priority-queue queue-limit 5 is?

Also, can someone explain the lines that start with wrr-

Can I get rid of these?  I believe they have something to do with QoS, but not sure.  If I can get rid of them, do I just do a (for example):
no wrr-queue random-detect max-threshold 3 70 70 80 80 90 90 100 100

Thanks,
Nick

priority-queue and wrr commands are both for qos.  Generally 'no' in front of the command will get rid of it.  Worst case scenario, clear the port by 'default interface gi9/11', then add back only the config you want.
