3750 - Show mls qos interface statistics

Hi All,
Sorry if this is posted in the wrong place but can anyone shed any light on the meaning of the five columns given in the output for the following command on a 3750 ?
Show Mls Qos Interface <interface id> Statistics
Many Thanks
Shaun

I think that this is my first post, so I hope it will be useful ;-)
It's indeed very strange, I faced the same problem before, so I tried to check older switches, and I was able to find what these values are, for example, if You check the link :
Understanding QoS Policing and Marking on the Catalyst 3550
http://www.cisco.com/en/US/products/hw/switches/ps646/products_tech_note09186a00800feff5.shtml
You will find that these five fields mean:
incoming   no_change       classified      policed    dropped (in pkts)
This is a description of the fields in the example:
Incoming—shows how many packets arrive from each           direction
NO_change—shows how many packets were trusted (such           as QoS level not changed)
Classified—shows how many packets have been assigned           this internal DSCP after classification
Policed—shows how many packets were marked down by           policing; DSCP shown before markdown.
Dropped—shows how many packets were dropped by           policing

Catalyst 3550 & 3560/3750 command 'show mls qos interface statistics'

On the Catalyst 3550 the command 'show mls qos interface statistics' will show ingress packet (or byte) counts with DSCP values. If you have policers configured then it also shows a count of packets that have been marked down to another DSCP value due to policing or any that have been dropped (obviously 'mls qos monitor dscp x' needs configuring). The same command on the 3560/3750 only shows the ingress & egress DSCP values, there is no column that shows packets (or bytes) that have been policed or dropped. Is there any command to display the same information with the 3560/3750?
Neither platform show counters when the command 'show policy-map interface x/x' is used so this won't work.
Thanks
Andy

Hi, I believe there is a command on the 3560 'sh mls qos interface policers' may be what you are looking for.
Here is what the command says it outputs:
To display QoS information at the interface level. This information includes:
The configuration of the egress queues and the CoS3-to-egress-queue map
Which interfaces have configured policers
Ingress and egress statistics, which includes the number of bytes that have been dropped

Show mls qos interface statistics equivalent command on Cat6500 SUP720-3B?

Hi all
Is there a command on the SUP720-3B that is similar to the show mls qos interface gi0/x statistics command on the access-layer series switches (3560 etc.)?
I'd like to see the incoming and outgoing DSCP/COS values in number of packets.
Thx :)

Hi,
You can use this command:
SUP720#show queueing interface xx
You should be able to see all that information there.
Hope this helps.

3560 mls qos interface statistics output

Hi
I've seen questions like this before, but never seen a satisfactory answer... I can't find any good documentation anywhere about this command.
If you run it, you get tabular output of some statistics - with no headers to the columns.
The closest thing I've found to it is in this document:
http://www.cisco.com/univercd/cc/td/doc/product/lan/c3550/12113ea1/3550cr/cli2.htm#wp2418191
It shows the fields as: Incoming, No_Change, Classified, Policed and dropped.
I have a switch with a modified cos-dscp map so that cos 5 is marked to dscp 46. This shows normal traffic as in the row titled 0-4 in the 'incoming' column, and cos 5 traffic appears in the 40-44 row and the 'dropped' column... which can't be right.
Anyone know what the columns mean?
Aaron

I figured this out after looking at it sideways and upside down. Here is part of the output from the command I ran on one of our 3750 switches (copy it and paste it into notepad so the rows stretch back out): 'sh mls qos int f0/35 statistics'
dscp: outgoing
0 - 4 : 63683 0 0 0 0
5 - 9 : 0 0 0 0 0
10 - 14 : 0 0 0 0 0
15 - 19 : 0 0 0 0 0
20 - 24 : 0 0 0 0 81
25 - 29 : 0 0 0 0 0
30 - 34 : 0 0 0 0 13366
35 - 39 : 0 0 0 0 0
40 - 44 : 0 0 0 0 0
45 - 49 : 0 10749 0 13653 0
50 - 54 : 0 0 0 0 0
55 - 59 : 0 0 0 0 0
On the left side X - X are the DSCP values for the five columns of that row. For example, 20 - 24 row has the number 81 in the fith column. That shows that 81 packets with the DSCP value of 24 went out of that port. In row 45 - 49, 10749 packets with DSCP of 46 and 13653 packets with DSCP value of 48 went out that port.
I finally was able to use this table to show that a video conferencing unit was truely generating voice packets with DSCP 46 (EF), video packets with DSCP 34, and call control packets with DSCP 24 (this is COS 3 that is mapped to DSCP 24 in the cos-dscp map entry.)
So to clarify, the five columns have nothing to do with Incoming, No_Change, Classified, Policed and dropped, they represent the number of packets that have the DSCP values as referred to by the far left table.
Hope this helps.

Cat. 3750 QoS Queue statistics

Hi all:
Does anyone know a way to see input and output queue statistics like occupation, number of frames discarded due to threshold reached etc ... on a Cat 3750
May be there exists a MIB...
Best regs.

the command "show mls qos interface" should help.
check out the following link for the command reference :

Hello !
My switch is Cisco IOS Software, C2960X Software (C2960X-UNIVERSALK9-M), Version 15.0(2)EX5, RELEASE SOFTWARE (fc1)
I try to disabled mls qos only for one interface, but when i do it, mls qos is globally disabled. Is it possible to do it ?

Denis

Hi Denis,
You cant disable the QOS on per interface on 2960 devices.
By default, QoS is disabled. When we enable QoS all ports
will be assigned to queue-set 1. We can configure up to two
different queue-sets.
Hence if you remove the qos out of the interface it would be disabled globally as well.

I am trying to identify what QoS marked packets are hitting an interface on my 4500E
Previously with the likes of the 2900 / 3500 I could collect the below information which was a great insight into the packets going through the interface. Is there anything like this for the 4500E on a Sup7? I've not been able to find anything.so far.

Hi,
I believe 4500E uses MQC style. if you have a policy map attached to the interface, you could use
sh policy-map interface <> <direction>
Hope this helps and Kindly rate all helpful posts.
Thanks,

Why does mls qos trust dscp dissapear after reboot?

The command takes but after reboot, Invlaid inputs detected show up and "mls qos tust dscp" is gone from every interface.
Happens on both 2960-24PC-S / 2960-48PST-S switches.

Hi,
thanks for your reply.

If i don't include the global 'mls qos' command then the voice packets keep the dscp 46 value. If I add the mls qos command this causes the switch to set the dscp values to zero.
Thanks again
ps. there are some other mls commands on the switch... i don't know if these could interfere but they were already on there so i'm reluctant to remove them..

Mls qos trust dscp??? is setting my DSCP values to zero!?

Hi,
I was just doing some testing to ensure that the command 'mls qos trust dscp' is working on my 6509 switches before rolling out QoS.
Before adding any configuration I could see using wireshark that traffic from my Avaya 9608 handset was coming through with a DSCP value of 46 (as it is supposed to).
I then added the command 'mls qos' (at global level)
on examining the wireshark output this time, the DSCP value had been set to zero (i.e. it defaulted it to best effort)
I then expected by adding the commmand 'mls qos trust dscp' on the interface the phone is connected to that the DSCP value would would again be left alone?
does anybody know why this is happening?
Many thanks in advance.
Andy

Hello,
I have two switches with ios, I want to configure the qos, but I have the error message:
Will I need to update the ios or is the platform switch that does not supporting this command?

I am answering this myself.
SW7(config)#mls qos srr input bandwidth ?

SW7(config)#mls qos srr input bandwidth 1 ?
<1-100> enter bandwidth weight for queue id 2
SW7(config)#mls qos srr input bandwidth 1 1 ?
<cr>
Its the weight that we mention here. Not the percentage directly.
SW2#show mls qos input-queue
Queue : 1 2
buffers : 90 10
bandwidth :   100     100
priority : 40   0
threshold1: 100 100
threshold2: 100 100
This will give 40% priority BW to queue and remaining 60% will equally share between bot the queues as their weights are same.

Without 'MLS QOS' in 6500 does any interface queueing and trusting take place?

I have a 6500 that does not have 'mls qos' global configured, although the interfaces do have 'mls qos trust dscp' on them as in:

switchport voice vlan 910
logging event link-status
mls qos trust dscp

When I 'show queueing int gx/x', it does show the default queueing structure of the interface as in:

So just what does the global 'mls qos' do? Without it is the command 'mls qos trust dscp' ignored?
I'm trying to track down where in our network dscp settings are being stripped out of packets and this is when I noticed the 'mls qos' was not configured.

it enables QOS on the switch, without it no QOS is being used.

MLS QOS problems on 3750

When i enable mls qos on 3750 running EMI image the ingress ports should switch to non-trusted and therefore reclassify all DSCP/COS bits to 0.
This is not happening and the COS bits are reamining as set by the IP handsets and pc's.
This does not happen on 3550 or 6500's which i have just tested to verify.

What is the exact version of OS you are using ?

Mls qos on Catalyst 3750

I can't understand dropping algorithm used by WTD on Catalyst 3750.
Giving the following configuration:
Switch(config)# mls qos queue-set output 2 buffers 40 20 20 20
Switch(config)# mls qos queue-set output 2 threshold 2 40 60 100 200
1. What happens if buffer utilization for queue 2 is between drop-threshold1 and drop-threshold2? Are the packets dropped using a specific algorithm as in WRED?
2. What happens if buffer utilization for queue 2 is between drop-threshold2 and maximum threshold? Are the packets dropped using another algorithm?
3. Is it true that with buffer utilization above maximum threshold all packets are dropped?
Thanks
Stefano

Paresh,
thanks a lot for your suggestions!
Anyway I still have some doubt related to WTD thresholds. The sintax is the following:
mls qos queue-set output qset-id threshold queue-id drop-threshold1 drop-threshold2 reserved-threshold maximum-threshold
For drop-threshold1 and drop-threshold2 the range is 1 to 400 percent. For reserved-threshold the range is 1 to 100 percent.
By default, drop-threshold1 and drop-threshold2 for queues 1, 3, and 4 are set to 100
percent. Drop-threshold1 and drop-threshold2 for queue 2 are set to 50 percent. The reserved
thresholds for queues 1, 3, and 4 are set to 50 percent. The reserved
threshold for queue 2 is set to 100 percent. The maximum thresholds for
all queues are set to 400 percent.
With these default settings, queue 2 has drop-threshold1 and drop-threshold2 set to 50 percent and reserved threshold set to 100 percent.
The problem is that drop-thresolds are percentage values related to the ENTIRE buffer, reserved threshold is related to the specific queue's buffer.
So with default settings (1/4 of total buffer for each queue) reserved threshold seems to be HIGHER than drop-thresolds!!!
reserved threshold = 1/4 total buffer
drop thresholds = 50% over 400% total buffer = 1/8 total buffer
Maybe there's something missing...
Thanks
Stefano

Show policy-map interface | Question about QOS show command output

I hope this is the correct place for this question. If not, please let me know.
When I issue the show policy-map interface command (in this case on a 3845) there is some output I don't understand. I have included some output below and formatted the lines I am confused about as "computer code" which show up as red on my screen. A list of the individual lines i'm confused about is below, followed by those liens in the context of the show policy-map command's output.
Any help with this will be greatly appreciated. Thanks in advance.
