SPA122 and auto QoS

It would be nice if the ATA could adjust its QoS automatically either by mean of clicking on a button from the Interface of by response to a SIP NOTIFY.
The response of a SIP NOTIFY would just return the new computed QoS so then you can just update the config and reboot the ATA at a convenient time.
Lots of routers out there does have this feature and I feel it would be quite a nice feature to have.
I'm just trying to improve the product here ...

How to enable auto QoS on C4500-X

How to enable auto QoS on C4500-X for Cisco phone? Since it is different from the global commands 'mls qos',who has the example? Thanks.

Cisco 2960x - auto qos voip cisco-phone on access ports

After configuring "auto qos voip cisco-phone" on a stack of 2960x switches, we later noticed that after a power cycle (config was saved first) it went missing when doing a "show run" from the interface configs, on one of the switches (g1/0/1-48 had it applied, then after power cycle it didn't show). However, doing a "show auto qos interface" shows it is still applied to all interfaces g10/1-48.
I try to do "auto qos voip cisco-phone" again on g1/0/1-48, and it shows this:
SwitchStack01(config-if-range)#auto qos voip cisco-phone
AutoQoS Error: AutoQoS already configured
% Range command terminated because it failed on GigabitEthernet1/0/1
If I attempt to remove "auto qos voip cisco-phone", it shows this:
SwitchStack01(config-if-range)#no auto qos voip cisco-phone
AutoQoS Error: AutoQoS not configured
% Range command terminated because it failed on GigabitEthernet1/0/1
When I do a "show run", it is no longer displayed for the first switch of the stack.So is it still applied to the interfaces or not? Is this a bug? Has anyone else experienced this? This has happened to at least a couple stacks of 2960x's we have.
Thanks!

It appears to be a bug in the code. Open a TAC ticket with Cisco and send them the output and the IOS version you are using so they can help you resolve the issue. Most likely, they recommend an upgrade.

Configure Auto QoS on WS-C4500X

Hi!!
I have two 4500X connected via VSS and on the edge I have 2960X and 3750. All edge switch have Auto QoS configuration activated for voip.
On 4500X I don't have the mls qos or qos only prompt to activate the QoS on the etherchannels.
Is there a different way on configure the Auto QoS on the 4500X?
I have the following software on my 4500X:

Hi Reza!!! Thanks for your reply.
I've looked on the net and found this blog http://blog.lah.io/2013/10/cisco-catalyst-4500-x-etherchannel-auto.html and thought that there is something wrong with my IOS, like a missing license.
I will read your guide and try to configure like that but you must agree that auto qos is far more easy and reliable. Strange that the guy on the blog can configure auto qos...

He is implementing ToIP. The topology is structured in the collapsed model where switches etherchannel uplinks have access to 2Gb Core.
On all access switches the "auto qos trust" for uplinks and the "auto qos trust cisco-phone" to access ports was implemented. In Core would have to disassemble the PortChannel, apply auto qos trust in the PortChannel interfaces and ride again.
The doubt is that setting the 4507R + E accepts the QoS on the doors of the Port Channel?
As this Release Notes http://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst4500/release/note/OL_27990-01.html
box in Release 3.2.3 does not support QoS on physical ports that composes the PortChannel.

Hi,
In this case as you pointed out, Auto-QoS is not supported on EtherChannel or its member ports. A physical port configured with Auto-QoS is not allowed to become a member of a physical port.
See the link below where you can find details about QOS on etherchannel:

Hope this helps.

Auto qos voip cisco-phone

Hello,
I am very new to voip, second day. I have configured a 3850 stack to trust cisco phones on the switchports with the auto qos feature. I am interested to know where else I have to apply qos for the policy's to apply. The 3850 stack is uplinked to a 4500x "core". My question is once the qos is applied at the switch port, is everything just grand and my qos will work or does it have to be applied elsewhere.
Thank you.
Dallas

It has to be applied all throughout your network. Ie Core switch, access layer, uplinks to voice servers/gateways and access ports to phones. If you have wireless phones, those will have to be considered as well.

3850 - auto qos voip cisco-phone

I am having an issue where it appears that the "auto qos voip cisco-phone" command is marking down my voice packets COS and DSCP values to 0. Anyone else notice this? I am connecting Cisco 7945 phone to the interfaces with this command applied to the interface. I verified that the IP Phone is sending COS = 5 and DSCP = ef to the switchport. I verified the packets inbound to the switchport and the packets outbound as they transit to the destination IP Phone's switchport.

Hi joshua,
What is the IOS-XE version you are running on your 3850 ?
Post your switchport configuration (7945 phone connected)
Here is 3.3 QoS config guide & I noticed it says something like below qouted. So make sure this trust device command is there & your port is configured for standard VoIP port connectivity.(like voice vlan, etc)
http://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst3850/software/release/3se/consolidated_guide/configuration_guide/b_consolidated_3850_3se_cg/b_consolidated_3850_3se_cg_chapter_01101000.html#reference_8A1C35AB2874498F90C4F5600301BE9D
"The trust device device_type interface configuration command is only supported in an auto-QoS configuration, and not as a stand-alone command on the switch. When using the trust device device_type interface configuration command in an auto-QoS configuration, if the connected peer device is not a corresponding device (defined as a device matching your trust policy), both CoS and DSCP values are set to "0" and any input policy will not take effect"

Auto QoS Voip Trust question

Hello,
I am a little confused on the auto qos voip trust command. I am reading that it should be used on interior switchports like trunk ports connected to another switch. I guess my question is this: If the auto qos voip command tells the switchport to trust the incoming CoS values, then isnt it redundant to tell the port to "trust" the incoming CoS value when the auto qos voip command is already accomplishing this? Or does this have something to do with trusting DSCP values instead of CoS values? If so, why are we trusting DSCP values at the uplinks and not CoS values coming from the IP Phone? Im so confused. Thanks for any light you can shed on this topic.
Chris.

Chris
Yes, the trust value used for "auto qos voip trust" depends on the operation of the port as you say.
And yes when you use the "cisco-phone" option it will trust the values but as you say only if it detects a Cisco IP phone and it does this by using CDP.
What is not entirely clear, at least to me, is exactly which markings the "cisco-phone" option trusts. There seems to be conflicting information but the configuration guide talk about DSCP markings so it may be those but i can't say for sure as i have limited experience in that area.

IEEE 802.1X auto-QoS

Hello,
Do Cisco switches implement QoS polices using 802.1X?
I found at Cisco 3560-X and 3750-X software configuration guide informations about 802.1x authentication with per-user ACL and authentication with VLAN assignment, but nothing related of QoS.
Could you help me please?
Thank you!
Allyson

Hi Claudia,
do you mean that the EAP-TLS authentication fails only on some 2960 switches and it works on other 2960s?
What is the IOS version you're using there?
What is the RADIUS server in use?
What is the exact error message you see on the RADIUS side?
Usually, the reason for the EAP-TLS handshake failure is to be troubleshoot on the supplicant and AAA server, however, there may be something on the switch depending on the certificate size and MTU settings on the switch(es).
What is the server cert size and the MTU configured on the switches?
With the info you provided it's difficult to say what's the reason of this failure.
I would suggest to start looking into the above mentioned topics, else you would need to proceed with deeper debugging and sniffer traces, which may be better/easier to handle through a TAC case.
I hope this helps.
Regards,
Federico

Nexus and 3850 QoS

Dear all,
I am having a problem with implementing QoS for a 3rd Party application. The vendor requests that some of this traffic needs special markings with specific cos/dscp values. Also we need to have QoS for our Cisco IP Phones.
The devices ( phones and the 3rd Party devices) are hooked up at the 3850 (running IP Base) switches which are connected via port channel to 2 Nexus 5596UP which are connected via vPC.
If i execute the
show policy-map int t1/1/4 or show policy-map int e1/1 on the switches, I can see that there are match packets ( matched by any) but 0 by the UDP ports.
Also the the 3rdParty Clocks are not synchron which is an indicator that the QoS is not working. If the two clocks are hooked up at the same 3850 switch they sync.
I am sure I miss something, but I really do not know what. The goal is to have QoS for the Cisco IP phones and also the 3rd Party devices.
Any help would be much appreciated.
Here the 3rd Party requests and configurations I did on the switches:

Auto QoS parameters on 2950

I have been looking at the way auto-qos behaves on a 2950 switch. Now, it used to be that the weightings given to the four WRR queues was 20 1 80 0. This made sense to me because it made a strict priority out of queue 4, which is the one that will get all my DSCP EF (i.e. voice) traffic.
I did this on a switch with version 12.1(22)EA4, and I see that the default weightings are now 10 20 70 1. This does not seem to make sense to me at all, and looks like the worst possible combination for voice. It is giving the least weighting to queue 4, which is the one carrying the voice traffic.
Is this a bug, or is there some reasoning behind it?
Kevin Dorrell

Kevin
This is a recent change in auto-qos on the 2950 from 20 1 80 0 to this 10 20 70 1. The reasoning is to get away from strict-priority queueing as it allows for starvation. In older code it still show 0 but new codes now show 1.
On the 2950 switches, This is done by design not to have a strict priority queue starve the other queues out. So this is expected behavior not to have a strict priority queue in newer versions of code when you use Auto QoS.
It is advisable not to give "strict" priority to any queue in order to prevent other queues from getting starved. On 2950, the wrr CLI allows weights of 1 - 255, and the weight of 0 is not configured (which would keep the queue in strict priority). One of the reason is that 2950 does not have features such as shaping. So, it is safer to keep the queues in round robin, and the number of buffers are controlled.
At this point it would probably be best to play with the weights to determine if the defaults work for your network. If the Auto QoS defaults do not work for your network you can always have the option to manually configure the CLI as you want.
Hope this helps.

Problems with .ARW files and auto toning

problems with .ARW files and auto toning
let me try to explain this because this has happened in past and never found a way to resolve but i lived with it
now that I have a Sony A7R the problem is more serious
Firstly i take pride it making the picture happen all in camera, i use DRO lvl 5 to get enough light, like when i'm shooting at dusk. DRO its like doing HDR but in a single file, it lightens the darks. in my camera i'm happy with results
but when I upload them to lightroom, they come out near black.
allow me to explain
lets say I import 100 images
i double check my preferences and everything is UNCHECKED when it comes to importing options, there is no auto toning, nothing.
as the images import i see a preview in the thumbnail which looks fine.
i double click on one to enlarge it, hence leave grid view.
for a brief 1 or 2 seconds, i see the full image in all its glory but than lightroom does something funny, it darkens the image
one by one as it inspects each image, if it was a DRO image it makes it too dark.
to make this clear, the image is perfect as it was in the beginning but after a few seconds lightroom for some reason thinks it needs to correct it.
how to prevent lightroom from doing this, i want the image exactly as it is, why must lightroom apply a correction>?
i think it has to do something with interpreting the raw file and lightroom applies its own algorithm.
but here is what i dont get.....before lightroom makes the change i'm able to witness the picture exactly as it was taken and want it unchanged..
now i have to tweak each file or find a profile for it which is added work.
any ideas how to prevent lightroom from ruining my images and just leave them as they were when first detected...
there are 2 phases...one is when it originally imports and they look fine
second is scanning each image and applying some kind of toning which darkens it too much.
thanks for the help

sorry thats the auto reply message from yahoo email.
i've disabled it now
thing is, there is no DRO jpg to download from the camera
its only ARW. so my understanding is when i use DRO setting, the camera makes changes to the ARW than lightroom somehow reads this from the ARW.
but then sadly reverts it to no DRO settings.
because i notice if i take normal picture in raw mode its dark but if i apply dro to it, it comes out brighter, yet when i d/l the image from camera to lightroom, which is an ARW - there are no jpgs. lightroom decides to mess it up
so in reality there is no point in using DRO because when i upload it lightroom removes it.
is there a way to tell lightroom to preserve the jpg preview as it first sees it.
its just lame, picture appears perfect...than lightroom does something, than bam, its ruined,.
what do i need to do to prevent lightroom from ruining the image? if it was good in the first place.

How can I continuously auto-save and auto-name the JPEG files with a controlled time interval

Hi,
I am newly involved in some Labview projects that out of my knowledge. I am trying to save multiple JPEG images from a live imaging task to a folder in the computer hard disk every certain minutes. I'd like to name these files with the date and time (eg. Img_06012011_1635. jpg).Then, after hours long image capturing, I can have all the image files in a neat order.
My goal is to have the jpg files auto saved and auto-named with the data and time at that moment. I also need to control this waiting time between each savings.
Could you please show me some hints about this? See the vi attached, I know I need to do something on the "write path" part on the up right corner. Thanks!
Solved!

Thanks, Steve. When I built up a path with the date and time info and send them to the WriteJPEG File.vi like you mentioned, it stopped saving any files into the folder. Do you think this is the problem from my while loop?Could you show me if there is any other secret functions that restrains the file saving?
I am planning to save the image files every 30 secs,for example, and then I can have a bunch of jpg files with their unique names after hours long image acquisition.
I appreciate you kindly help!
