Mls qos trust
Hello, if the command 'mls qos trust xxxxx' is not issued, and qos is turned on for the interface, does this mean the switch will erase all cos and dscp markings received, therefore preventing me from testing packets/frames against these cos/dscp values ?
So if I want to set up class maps, policy maps, and then service policies, it is essential that I:
1. turn on mls qos ?
2. enter a trust statement in order to preserve the cos or dscp values that I want to test against ?
3. now I can test against against cos or dscp values ?
Thanks for clarification.
That is correct, when you would use for instance mls qos trust cos. You would need to define you cos<>dscp mappings on the switch and the switch will apply qos accordingly.
So really if you have an ingress switch port and you trust cos or dscp, you can still have egress policies on a port (on the same switch), using these cos or dscp values.
the mls qos trus command is just a way to make it easier to rely on existing cos/dscp values that a phone sends (based on your CUCM configuration,), without the need for you having to configure it explicitly on each access port.

Cisco 3560 switch| mls qos trust dscp question
Hi everybody
Hi everybody .
Please consider the following example:
3560 sw f1/1--------trunk---SW2
3560 sw
f1/1
mls qos trust dscp
3560 is using default cos-dscp map, assume a 3560 receives a frame carrying IP packet on f1/1 with COS 4, what will 3560 switch do?
1) will it use its default cos --dscp map ( cos 4--.dscp 32) and rewrite 32 in dscp field of the packet in the frame and provide PHB for dscp 32 ?
Much appreciated!!
Have a great weekend.Hi
No it will not trust the cos value, because You have configured to trust dcsp. So, the switch will trust the dcsp value in the incoming frame.

Hello world!
I want to enable qos on a 3560 switch,
So, I put:
Overall setup mode "mls qos"
Question:
is what it is Verily nessaiire to interface configuration mode: "mls qos trust"?

Generally, on many Catalyst switches, once you enable QoS, they will erase an ingress CoS/ToS markings unless your trust it or otherwise (i.e. policy) maintain it.
I.e. the answer to your question is an "it depends"; but unless you want the markings reset to zero, the answer is probably yes (you want to trust). -
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.
AndyHi,

Mls qos trust{cos/ip-precedence/dscp} command
Hi every body!
I have few questions
1)
The command " mls qos trust dscp" is only valid on mulilayer switch or it is also valid for layer 2 switch? If layer 2 switch is configured with that command, can it modify the dcsp value based on policy?
2)is the following correct:
switch(config-if) mls qos trust dscp
switch will set the cos value to set default. If the default set is zero, then frame will be processed by best-effort delivery.
But the egress-queue will be decided by dscp value in the packet. A dscp to cos map will be used to drive the cos value and then frame will be placed in the queue that corresponds to cos value.( off course if egress port is configured for trunk)
thanks a lot and I wish America and all of you a happy new year!
thanks a lot!Sarah
1) L2 switches can trust the dscp marking as well. The 2960 is a layer 2 only switch and the default is untrusted but if you then enter
"mls qos trusted" you have a choice of 'cos|dscp|ip-precedence'. The default if no choice is entered is DSCP.
2) If "mls qos trust dscp" is entered then the switch will use the DSCP marking found in the packet. This will then be used as the internal DSCP marking that all switches use. Unless you have a DSCP-DSCP mutation map the value used will be the value received in the packet.

Mls qos trust cos vs mls qos cos in cat6k
Hello
I am trying to configure basic qos topology with two 6k connected to each other by the trunk port.
According to the documentation, if I set the mls qos cos value at the interface level I should modify the default cos on it, and all packets leaving incoming to this port, should be marked with the new cos value.
http://www.cisco.com/c/en/us/support/docs/switches/catalyst-6000-series-switches/24055-173.html
Unfortunately, when I set such config, all incoming packets transmitted through this interface was tagged with cos = 0 until I set the "mls qos trust cos" on the same interface.
Does anybody can explain to me this strange behavior?
I would like to mention that both 6k was connected to each other with ws-x6548-GE-TX modules.
Thank you in advance.

"mls qos trust dscp" vs. "mls qos trust cos"
Are these statements correct ?
1. If using QoS profile without setting "wired qos protocol", always use "mls qos trust dscp" on the WLC trunk port
- downstream wmm traffic will be policed down to "?" (this one I'm not sure, is it "not policed" or "policed down to cos 6 for platinum, etc")
2. If using QoS profile with setting "wired qos protocol",
- use "mls qos trust cos" on the WLC trunk port if you want outgoing LWAPP traffic COS/DSCP to reflect QoS profile setting and if you want to rewrite DSCP in the outgoing upstream traffic to QoS profile setting
- use "mls qos trust dscp" on the WLC trunk port if you want LWAPP traffic COS/DSCP to reflect original DSCP setting and if you want to leave DSCP alone in the outgoing upstream traffic
3. With either "mls qos trust cos" or "mls qos trust dscp" on WLC trunk port, downstream wmm traffic will be policed down to "wired qos protocol" setting (What if "wired qos protocol" is not set, will it be policed down to, for example, cos 6 for Platinum?)
4. Always use "mls qos trust dscp" on non-HREAP AP ports
Use "mls qos trust dscp" on HREAP AP ports, if you want to preserve upstream DSCP for locally switched WLANs
Use "mls qos trust cos" on HREAP AP ports, if you want to QoS profile 802.1p to override upstream DSCP for locally switched WLANs
5. Use either "mls qos trust dscp" or "mls qos trust cos" on switch-to-switch trunksAre these statements correct ?

- downstream wmm traffic will be policed down to "?" (this one I'm not sure, is it "not policed" or "policed down to cos 6 for platinum, etc")
Ans: Not sure about always. you can use both 'mls qos trust dscp' and 'mls qos trust cos'. Since it is a trunk port the packets will have a cos value (802.1p tag) and hence you can trust cos. Downstream and upstream traffic both are capped to the WLAN max QoS value. for example if Wlan is set to silver, and if a packet comes in at platinum QoS, the AP will cap it to silver in upstream direction. Same holds true for a cos 5 / dscp 46 packet coming in from the wired side.
2. If using QoS profile with setting "wired qos protocol",
- use "mls qos trust cos" on the WLC trunk port if you want outgoing LWAPP traffic COS/DSCP to reflect QoS profile setting and if you want to rewrite DSCP in the outgoing upstream traffic to QoS profile setting
- use "mls qos trust dscp" on the WLC trunk port if you want LWAPP traffic COS/DSCP to reflect original DSCP setting and if you want to leave DSCP alone in the outgoing upstream traffic
Ans:
3. With either "mls qos trust cos" or "mls qos trust dscp" on WLC trunk port, downstream wmm traffic will be policed down to "wired qos protocol" setting (What if "wired qos protocol" is not set, will it be policed down to, for example, cos 6 for Platinum?)
Ans: Traffic in both direction wil always get capped to WLAN max QoS. Untagged (802.1p = 0) traffic will be treated as best effort.
4. Always use "mls qos trust dscp" on non-HREAP AP ports
Use "mls qos trust dscp" on HREAP AP ports, if you want to preserve upstream DSCP for locally switched WLANs
Use "mls qos trust cos" on HREAP AP ports, if you want to QoS profile 802.1p to override upstream DSCP for locally switched WLANs
Ans:
5. Use either "mls qos trust dscp" or "mls qos trust cos" on switch-to-switch trunks
Ans: I think on purely layer 2 switches you can trust dscp, but am not 100% sure. -
I have an uplink from an access switch configured as a trunk 802.1q that needs to trust Qos towards the distribution switch, does this have to trust cos or dscp ? the issue is that the access switch has a local voice vlan and the trunk uses another vlan to connect to the distribution.
You don't trust "to" a device, only from.
The advice I've gotten from switching guys is "If you're not sure - just trust DSCP".
If you try to trust cos on an access port where there is no VLAN header, there is no cos, and you can have problems.
If you have a trunk to another switch, you can trust cos and you shouldn't have any problems.

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:
interface GigabitEthernet3/3

switchport mode access
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.
Sent from Cisco Technical Support iPhone App -
Was going thro one of the document on METRO QOS and came across 2 commands "mls qos trust cos pass-through dscp" and second one is "no mls qos rewrite ip dscp ".Can any please elaborate these commands and share difference between them.
1.mls qos trust cos pass-through dscp -- To configure the multilayer switching (MLS) port trust state and to classify traffic by examining the class of service (CoS) or differentiated services code point (DSCP) value.
2.no mls qos rewrite ip dscp-- To enable type of service (ToS)-to-differentiated services code point (DSCP) rewrite, use the mls qos rewrite ip dscp command in global configuration mode. To disable ToS-to-DSCP rewrite, use the no form of this command

Thank you.Hi,
QOS implementation has radically changed since the advent of
sup-7 & later
You no longer set mls qos as qos is on the engine by default.
Please see the following links
http://www.cisco.com/c/en/us/products/collateral/switches/catalyst-4500-series-switches/white_paper_c11-539588.html
"Ingress QoS: Default Actions
First and foremost, QoS does not need to be enabled on the Supervisor Engine, it is on by default in compliance with the MQC construct.
When a packet arrives at an interface, there are two options to take into consideration: is there a policy attached or not? If the packet arrives with or without a marking and there is not a policy attached to the interface, packets will flow through the switch untouched. There are no questions as to where the packet came from or if it has a valid marking. If the packet arrives with or without a marking, and a policy is attached to the interface, the packet will only then be subject to the policy classification."
And the config guide
http://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst4500/15-1/XE_330SG/configuration/guide/config/qos_mrg.html#wp1461453
Hope this helps

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
ShaunI 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 -
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 ?
Maybe you are looking for
