Enabling #mls qos globally on 3650 switch
Hi,
I just got a WS-C3650 switch, Trying to configure #mls qos but it seems as if this switch does not support this feature.
Is there a way of enabling it?
Regards
Pardon
Hey,
Its enabled by default, as this box uses MQC for QoS. Check the link:

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
switchport access vlan 536
switchport mode access
switchport voice vlan 910
logging event link-status
mls qos trust dscp
spanning-tree portfast
When I 'show queueing int gx/x', it does show the default queueing structure of the interface as in:
LLT-6509AS-A#sh queueing int g3/3
Interface GigabitEthernet3/3 queueing strategy: Weighted Round-Robin
QoS is disabled globally
Port is untrusted
Extend trust state: not trusted [COS = 0]
Default COS is 0
Queueing Mode In Tx direction: mode-cos
Transmit queues [type = 1p3q8t]:

Packets dropped on Transmit:
BPDU packets: 0

Packets dropped on Receive:

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.

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 ?

Enabling MLS QOS on 2960S seems to "throttle" bandwidth when using a specific Mitel 5320 phone. I have a PC behind the Mitel and the performance is way slower. Validated via a speed test. Once I remove the MLS QOS globally, the performance is greatly improved, about doubled. This is causing some issues as users with this particular phone attached with a PC behind the phone are starting to complain. What could be causing this or what settings to overcome this?

Enabling QoS on a 2960/3560/3750, using defaults, often results in slow transfer performance. This because the default buffer settings often increase drop rates in the newly enabled egress queues. Manual buffer tuning might mitigate. -
"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 ?
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")
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. -
Mls qos enabled globally and disabled for only one interface

Thanks in advance for your help !!
DenisHi 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.

Cisco 3650 QoS design: "mls QoS" not supported
Dear colleagues,
I am currently testing a Cisco 3650 for various catalogue items. One key feature that we use on almost all our catalogue items, is Quality of Service (QoS).
On the old Cisco 3560 and 3750, we use "mls qos" and related commands. We use numbered ACLs for untrusted QoS policy that sits on the LAN / ingress port. I have raised a TAC case for this issue but is there a tool to help me convert the "mls QoS" design on the old 3560 platform to the new 3650 platform where "mls qos" is not supported?
Many thanks.Hi,
The new 3650 runs IOS-XE and the older Cisco 3560 and 3750 run IOS. So the QOS architecture on the new 3650 is different.
here is the link to the qos config for the 3650:
http://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst3650/software/release/3se/qos/configuration_guide/b_qos_3se_3650_cg/b_qos_3se_3650_cg_chapter_011.html

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.

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

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

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.

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

NAT problems on a L3 3650 switch
So, I am trying to setup NAT on our new 3650 switch running IOS-XE Software, Catalyst L3 Switch Software (CAT3K_CAA-UNIVERSALK9-M), Version 03.06.00E RELEASE SOFTWARE
This simple setup involves a layer 3 port (1/0/46) to our gateway and a Vlan for NAT
My hosts on my NAT Vlan (Vlan 2) do not seem able to ping anywhere else than the switch itself (all its interfaces) and their local subnet. Pings from the switch to outside are fine (NAT debug enabled):

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).
