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:
Protocol: PTP
Destination: 224.0.1.129
Dest.Port: UDP319,320
DSCP: CS7
CoS: 56
Protocol: Unicast Streaming
Dest.Port: UDP 14336-14600
DSCP: EF
CoS: 46
Protocol: Broadcast Streaming
Dest. Port UDP 4321
DSCP: EF
CoS: 46
I created the following Class Maps, ACLs and Policy Maps on the Nexus Switches for 3rd Party and Voice:
ip access-list ACL-Dante-Audio
10 permit udp any any eq 4321
20 permit udp any any range 14336 14600
30 permit ip any any
ip access-list ACL-Dante-PTP

20 permit udp any any eq 320

The following settings are configured on the 3850's:

After a few tries we found solution.
Solution is customizing cisco av pair, it must looks like:

Routing issue between Cisco Nexus and Cisco 4510 R+E Chassis
We have configured Cisco Nexus 7K9 as core and Cisco 4510 R+E as access switches for Server connectivity.
We are experiencing problem in terms of ARP learning and Ping issues between Cisco Nexus and end hosts.Hi,
So you have N7k acting as L3 with servers connected to 4510?.
Do you see the MAC associated with failing ARP in 4510?. Is it happening with all or few servers?. Just to verify if it is connectivity issue between N7k and 4510, you can configure an SVI on 4510 and assign address from same raneg (server/core range) and perform a ping.
This will help narrow down if issue is between server to 4510 or 4510 to N7k.
Thanks,

Hello,
I am trying to upgrade from 3750 to 3850. Following is my outbound WTD qos config on 3750:

What will be the equivalent config for the 3850? I am not able to find the right documentation for 3850.
Following is what I created but I believe it wouldnt handle WTD.

Also, when I try to apply this to an interface, it accepts it but its not visible under show runn. Am I missing anything?
I would appreciate any help with this.
Thank you.Hi,
3850 is not supporting MLS QoS (so any QoS commands start with mls keyword is not applicable in this switch platform- even thoug they are accepted).
It is a MQC QoS based switch platform (like 6500,4500). There are few Queing models (1P7Q3T, 2P6Q3T for wired & 2P2Q for wireless) supported in this platform. Please refer below post for more detail
http://mrncciew.com/2013/12/23/3850-qos-part-2-queuing-models/
Based on this you need to derive your config changes. As you can see in the above "queue limit x " is the command used to configure WTD for non-priority queues (ie Q2 to Q6)
Regarding running config, you can use "show running-config all" command to see all the configuration lines of your switch including default configs

Upgrade LIC for 5760 and 3850(L-LIC-CTIOS-1A)
Hi ,
the license part number (L-LIC-CTIOS-1A) is available from both 5760 primary upgrade LIC and 3850 Primary upgrade LIc with same prices as well
My Question is,
if i purchase L-LIC-CTIOS-1A with the primary upgrade lic as
L-LIC-CT5760-UPG
Upg license SKU for Cisco 5760 WirelessController (e-deliv)
will i be able to use it for 3850 switches as well because the primary upgrade LIC for 3850 is
L-LIC-CT3850-UPG
Upg license SKU for Cisco 3850 WirelessController (e-deliv)
Hope i am clear and if anybody has come across this suitation please replyFound the answer
it can be transferred between 3850 and 5760 controllers

AP License for Cisco Catalyst 3850
There is no license required for a Cisco Catalyst 3850 to operate as a distributed termination point for Access
Points (Mobility Agent mode). The same switch can also operate in the full controller Mobility Controller (MC)
mode by adding an AP license for up to 50 Access Points. Other devices that can act as an MC are the new Cisco
Wireless Controller 5760, Cisco Wireless Controller 5508 and Cisco Wireless Services Module 2 (WiSM2)
wireless controllers. AP licenses can be transferred between two 3850 switches or between 3850 and 5760

3850 QoS class-map match-all?
I would like to create a QoS marking policy that re-marks packet to CS5 if the inbound traffic is SIP *and* if it is marked CS3 when it comes in. I would have expected the configuration listed below will work. I only found out when I tried to apply the config that, unlike other IOS devices, "class-map match-all" does not exist in 3850 3.3.x code. It can only do "class-map match-any" Can anyone suggest a work-around config for 3850 to achieve the same end result?
ip access-list extended ACL-QOS-SIP
permit tcp any range 5060 5061 any
permit tcp any any range 5060 5061
ip access-list extended ACL-QOS-CS3

Ciscoworks LMS 4.0.1 and 3850 switch support
HI, I want to know if 3850 switch is supported in ciscoworks LMS 4.0.1, I added the devices, inventory collections successful but devices icon is blue with question mark "?" and config sync fails always.
I tried to download the packages to install it but I couldn't find it.
thanks fo helpYes LMS 4.2 needs a new license. You can probably check once if your LMS 4.0.1 license allows you a free upgrade.
Many old LMS 4.0.1 were offered free Cisco Prime Infrastructure 1.x, which has LMS 4.2 available with.
You can check the contract covering your LMS 4.0 on Product upgrade tool :

A fix for nexus and Chromecast on bt
Been struggling for a few weeks now casting from my nexus to Chromecast via BT but have finally found a solution.
First of all make sure your google play services is the latest addition you can find the latest version here http://www.apk4fun.com/apps/com.google.android.gms/ after installation turn your device off and back on and try to cast if it does not work do the following which worked for me.
First of all install a older version of play services once installed go into your app manager and force stop google play services
Turn of your device and then back on.
Go back to your google play services and restart the play services.
Then go to your Chromecast and start it up, it will tell you that it needs the latest version of play services to work, follow the on screen instructions and let it update.
Once done exit everything and turn the device on and off then reconnect to your Chromecast and you should be good to go.
If not pester google like I did, it has nothing at all to do with the BT home hub all issues are Google's latest updates.Hey, thanks!
I was having the exact same problems in Final Cut Studio 2
Motion crashes/closes on 'save as' or export.
DVD studio pro crashes on import.
Soundtrack Pro crashes on save as.
Final cut pro 6 was the only one that worked fine. Not sure about LiveType, havn't used that in like 4 years.
JUST A WARNING:
Final Cut Pro X will not open after this fix!
Any ideas of how to get both FCS2 and FCPX working on the same machine in Snow Leopard? I like editing in FCPX (for my needs it's faster) but I still need DVDSP. :/
Any point upgrading to FCS3 or will that crash as well?
---------------Or is there an alternative to DVD SP that's free or not too expensive????------------------
For those that need it, here's the reverse process:
(This worked just fine for me to reverse the process and get FCPX to work again, HOWEVER, I am NOT qualified to give this advice, I am not a programmer or developer! - do the following at your own risk.)
Open Terminal and enter the 4 lines below and press 'enter' after each line:
cd /System/Library/PrivateFrameworks/
sudo mv ProKit.framework "ProKit(SnowLeopard).framework"
sudo mv ProKitFOO.framework ProKit.framework
exit
I hope that's been helpful to someone.

Cisco 7600 MPLS and set Qos group
Hi, i'm am trying to use to following class-maps and policy maps on a Cisco 7600. The same maps have been used on both 3700 series and 7200 series. However when i try to apply IP_TO_MPLS_OUT and MPLS_TO_IP_IN on the 7600 (with SUP32 and 48 port gigabit blade) i get a message on the console
"set qos group" not supported.
I used the QoS group to carry the MPLS EXP value (as label would is popped) and this works well.
How can i get the QoS group to work on the 7600, if not is there a valid workaround?
Many thanks for your help.

I'm not aware that you can use qos groups on c7600 (LAN ports ?).
For the MPLS_TO_IP direction you can use 'mpls propagate-cos' on the egress interface as workaround. This rewrites the egress IP ToS with the internal DSCP (which is inferred from the topmost MPLS label).
For the IP_TO_MPLS direction you could just match on the original DSCP ?
cheers,

Looking for some details on do's and dont's for Multi-VRF CE. Also wondering how CoS/QoS is supported. If I want to do CBWFQ on the CE that is supporting Multi-VRF CE can I do it per subinterface to have a policy per VRF?
It depends on what platform you are using. The 7200 and 7300 do not support CBWFQ on sub-interfaces right now. Ive heard September this year but wont hold my breath. The 12k supports it but only on the E3 card not the 10portgigE4+ card.

How to clear Cat 3850 QoS Counter

Cisco VSS Dual-active PAgP detection via Nexus and vPC
Hi!
We will soon implement Cisco nexus 5595 in our Datacenter.
However we will still be using a pair of C6500 in a VSS in some part of the network.
Today we are running dual-active detection via a PAgP Port-channel, but those Port-channels will be removed and the only Port-channel we will have is to a pair of Nexus 5596.
Does anyone know if we can run PAgP dual-active detection via this MEC/vPC?
Thank you for your time!
//OlleHi,
The easies way is to connect both links from the 6500s to only one of the Nexus switches. Than create a portchannel on both the 6500 and the Nexus.
The other option would be to connect the 6500s directly together via a gig link and use fast hello instead of epagp.
I would use fast hello since it is supported on the 6500s.

Has anyone every managed to prioritise H323 on Cisco routers. I have tried loads of ways, but it seems to make the VC worse. What gives? I have set polycom to fixed ports and tried custom queueing on these fixed ports and also priority queuing, but to no avail. Both methods result in a worse quality VC session. Has anyone got any tips?? I have this setup in a test lab with 4 x Cisco 2611, 1 x Cisco 7204 and 4 x Catalyst 2924.
Is there a whitepaper on the proper way to provide QoS for video as it pertains to IP Prec, DSCP, and Queuing?
any help is great
Best RegardI am using Cisco 3640s and Polycom to implement VTC. We only use IP for the VTC and they turn out pretty good. I have implemented both RTP priority and Priority queuing alone and at the same time and have had good results. How did you have your priority queue built? The one that I use now has all the video traffic that comes in on Fa0/1 assigned to the high queue. all the rest goes to the default queue. I just assign this queue to the serial port and it goes. I have also used IP RTP priority and specified the ports that the Polycom uses (3230-3235 I think) and that seemed to work as well. just type in Priority queueing or IP RTP Priority at Ciscos web page and you'll get loads of info. Hope that this helps.
you can e-mail me at [email protected] if you want some more info on how we did it.
