[OSL | CCIE_Voice] drop packets from 3750 output queue 2
I have a switch qos item I am not sure how to address: When queue 2 reaches 60% capacity COS 4 packets should be dropped. COS 4,6,7 is mapped to queue 2. any ideas?

Re: [OSL | CCIE_Voice] drop packets from 3750 output queue 2
Hi, Ingress or egress?? My quess it to put COS 4 into different threshold than COS 6 and 7 and for egress tune queue-set assigned to the interface. I assume that auto qos was run before. *! put cos 4 in Q2 threshold 1 *mls qos srr-queue output cos-map q 2 t 1 4 *! tune dscp to queue map as it has precedence over cos to queue map if maps are inconsistent *mls qos srr-queue output dscp-map q 2 t 1 32 *! configure queue-set 2 with threshold 1 set to 60% *mls qos queue-set output 2 threshold 2 60 100 100 400 *! assign queue-set 2 to the interface *int f0/2 queue-set 2 Any comments welcome :) -- Regards, Bartosz 2011/6/2 adam compton com...@gmail.com I have a switch qos item I am not sure how to address: When queue 2 reaches 60% capacity COS 4 packets should be dropped.

CoS 4,6,7 are probably mapped to queue 2 threshold 2. Just move CoS 4 to queue 2 threshold *1*, then make sure the threshold settings for queue 2 are 60 100 100 100 (the last 3 values aren't critical, you just need the 60 so that CoS 4 packets are dropped starting at threshold 1 - 60%). cheers, sd From: ccie_voice-boun...@onlinestudylist.com [mailto:ccie_voice-boun...@onlinestudylist.com] On Behalf Of adam compton Sent: Thursday, June 02, 2011 1:10 PM To: ccie_voice@onlinestudylist.com Subject: [OSL | CCIE_Voice] drop packets from 3750 output queue 2 I have a switch qos item I am not sure how to address: When queue 2 reaches 60% capacity COS 4 packets should be dropped.

Re: [OSL | CCIE_Voice] drop packets from 3750 output queue 2
So I did a little bit of reading. Auto QOS was mapping COS values to the queues at threshold 3. I mapped COS 4 to queue 2 threshold 2: mls qos srr-queue output cos-map queue 2 threshold 2 4 So I know that the command is something like someone listed: mls qos queue-set output 2 threshold 2 60 100 100 400 What do each of the numbers mean? From what I've seen, I don't think the last two would apply at all, but it seems like the first two are a min-max type setting. I almost understand it, but just don't get what these values are.

Re: [OSL | CCIE_Voice] drop packets from 3750 output queue 2
I agree with Bartosz and Steve's answers i'd check the threshold and associate COS 4 to Queue 2 on a either threshold 1 or 2 and then modify the threshold to be 60% or whatever they're asking 2011/6/2 Steve Denney (stdenney) stden...@cisco.com CoS 4,6,7 are probably mapped to queue 2 threshold 2.
