Updated to 8.10.112.0 and it appears to be working, albeit in 802.11b mode. I think it may be related to this bug: https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvs63543 Current 2.4GHz channel is 11. I don't remember what it was before. ... View more

I would really like to take advantage of QOS but only if the link is saturated. It would be really nice to have voice or other tagged traffic take priority over SMB (unclassified) traffic but I don't see a reason to drop SMB traffic (like it is now) if there is more than enough bandwidth on the link.   Did the  buffer assignment increase after I rebooted with:  " qos queue-softmax-multiplier 1200"? ...

What if I just want the switch to not strip the DSCP tags? How do I tell it to keep the tags? ... View more

All unclassified traffic is getting effected. I'm not sure why because I thought QOS was only suppose to kick in when there was no bandwidth left. I tested this on a dedicated 1Gbps link and it still throttles unclassified traffic and drops it. ... View more

Oh, I most definitely have an issue. Not just going by stats here. Can't stream audio or video files from an SMB share without buffering. ... View more

I rebooted the switch late last night to see if "qos queue-softmax-multiplier 1200" needed a reboot to take effect. The counters have been reset as a consequence. It probably won't show many drops until later on today but here you are in the meantime.   1.  show pla hard fed sw active qos queue config interface gig 1/0/3 DATA Port:27 GPN:1352 AFD:Disabled FlatAFD:Disabled QoSMap:3 HW Queues: 216 - 223 DrainFast:Disabled PortSoftStart:4 - 5400 ---------------------------------------------------------- DTS Hardmax Softmax PortSMin GlblSMin PortStEnd ----- -------- -------- -------- -------- --------- 0 1 7 45 9 45 5 0 0 0 6 7200 1 1 4 0 10 360 9 80 4 30 6 7200 2 1 4 0 11 1440 9 80 4 30 6 7200 3 1 4 0 11 1440 9 80 4 30 6 7200 4 1 4 0 11 1440 9 80 4 30 6 7200 5 1 4 0 11 1440 9 80 4 30 6 7200 6 1 4 0 11 1440 9 80 4 30 6 7200 7 1 4 0 12 3600 10 200 5 75 6 7200 Priority Shaped/shared weight shaping_step sharpedWeight -------- ------------- ------ ------------ ------------- 0 1 Shaped 850 255 0 1 7 Shared 125 0 0 2 7 Shared 125 0 0 3 7 Shared 125 0 0 4 7 Shared 312 0 0 5 7 Shared 1250 0 0 6 7 Shared 125 0 0 7 7 Shared 50 0 0 Weight0 Max_Th0 Min_Th0 Weigth1 Max_Th1 Min_Th1 Weight2 Max_Th2 Min_Th2 ------- ------- ------- ------- ------- ------- ------- ------- ------ 0 0 71 0 0 80 0 0 90 0 1 0 286 0 0 320 0 0 360 0 2 0 1147 0 0 1282 0 0 1440 0 3 0 1147 0 0 1282 0 0 1440 0 4 0 1147 0 0 1282 0 0 1440 0 5 0 1147 0 0 1282 0 0 1440 0 6 0 1147 0 0 1282 0 0 1440 0 7 0 2868 0 0 3206 0 0 3600 0 2.  show pla hard fed sw active qos queue stats interface gig 1/0/3 DATA Port:27 GPN:1352 AFD:Disabled FlatAFD:Disabled QoSMap:3 HW Queues: 216 - 223 DrainFast:Disabled PortSoftStart:4 - 5400 ---------------------------------------------------------- DTS Hardmax Softmax PortSMin GlblSMin PortStEnd ----- -------- -------- -------- -------- --------- 0 1 7 45 9 45 5 0 0 0 6 7200 1 1 4 0 10 360 9 80 4 30 6 7200 2 1 4 0 11 1440 9 80 4 30 6 7200 3 1 4 0 11 1440 9 80 4 30 6 7200 4 1 4 0 11 1440 9 80 4 30 6 7200 5 1 4 0 11 1440 9 80 4 30 6 7200 6 1 4 0 11 1440 9 80 4 30 6 7200 7 1 4 0 12 3600 10 200 5 75 6 7200 Priority Shaped/shared weight shaping_step sharpedWeight -------- ------------- ------ ------------ ------------- 0 1 Shaped 850 255 0 1 7 Shared 125 0 0 2 7 Shared 125 0 0 3 7 Shared 125 0 0 4 7 Shared 312 0 0 5 7 Shared 1250 0 0 6 7 Shared 125 0 0 7 7 Shared 50 0 0 Weight0 Max_Th0 Min_Th0 Weigth1 Max_Th1 Min_Th1 Weight2 Max_Th2 Min_Th2 ------- ------- ------- ------- ------- ------- ------- ------- ------ 0 0 71 0 0 80 0 0 90 0 1 0 286 0 0 320 0 0 360 0 2 0 1147 0 0 1282 0 0 1440 0 3 0 1147 0 0 1282 0 0 1440 0 4 0 1147 0 0 1282 0 0 1440 0 5 0 1147 0 0 1282 0 0 1440 0 6 0 1147 0 0 1282 0 0 1440 0 7 0 2868 0 0 3206 0 0 3600 0 core3850# core3850#show pla hard fed sw active qos queue stats interface gig 1/0/3 DATA Port:27 Enqueue Counters --------------------------------------------------------------------------------------------- Q Buffers Enqueue-TH0 Enqueue-TH1 Enqueue-TH2 Qpolicer (Count) (Bytes) (Bytes) (Bytes) (Bytes) - ------- -------------------- -------------------- -------------------- -------------------- 0 0 0 128 5726106 0 1 0 0 0 0 0 2 0 0 0 0 0 3 0 0 0 0 0 4 0 0 0 0 0 5 0 0 0 0 0 6 0 0 0 0 0 7 0 0 0 287220 0 DATA Port:27 Drop Counters ------------------------------------------------------------------------------------------------------------------------------- Q Drop-TH0 Drop-TH1 Drop-TH2 SBufDrop QebDrop QpolicerDrop (Bytes) (Bytes) (Bytes) (Bytes) (Bytes) (Bytes) - -------------------- -------------------- -------------------- -------------------- -------------------- -------------------- 0 0 0 0 0 0 0 1 0 0 0 0 0 0 2 0 0 0 0 0 0 3 0 0 0 0 0 0 4 0 0 0 0 0 0 5 0 0 0 0 0 0 6 0 0 0 0 0 0 7 0 0 0 0 0 0 ...

I'm having trouble understanding your English but I don't believe this should be happening. On a 1Gbps link (actually 2Gbps here with LACP) with no other traffic, unclassified data should not be dropping since there is nothing of priority to preempt it. It is my understanding that QoS should only take effect if the link is saturated. This is not the case here. I am seeing drops on an unsaturated link just because the data is not DSCP tagged. ...
