I'm pretty sure there is no RF Profile or any custom settings just a global setting and its 1, 6, 11. Country is US 802.11bg:-A    802.11a:-A   Now one thing I'm noticing that AP's with a part number -B in them does not have this error message. I can understand that for 5 GHz but why for 2.4 GHz?   Update: Found other AP's with 802.11bg:-A    802.11a:-A and not throwing that message. ... View more

I understand the client limitations and using only channels that are supported by the clients.  Already know that part and have verified all that using pcaps and vendor tech specs.  Back to the main question.  I still need to know why Cisco document says that WLC will not use those channels in US and Canada.  Because that statement is not true.   1- Cisco 2602 is 802.11n and I was not able to assign 116 or 140 manually with 40MHz width.  Makes sense on 140 as 40MHz because 144 was allowed when ac came out    2- Cisco 3800 which is ac wave 2, allows manual configuration of both 116/120 and 140/144 at 40MHz.     3- Cisco’s statement in that doc states that WLC will not use those channels however I have seen RRM utilize those channels especially on IW3700s so technically that statement is wrong and/or doesn’t make sense because those channels do get assigned.     So is it possible that the document needs updating ?  Hope this makes more sense.  It’s critical to verify this statement from Cisco due to multiple reasons hence I’m trying to find something solid on that.   Thank you. ...

Got it thank you for confirming. Hopefully with some heavy fine tuning RRM will make better decisions now. I don't know why Cisco won't add that feature. ... View more

Thank you Leo, I should have explained better.  I know how to do all that but what I am looking for a way so that I can prevent OBSS issue.  I want to be able to specify to only bond up or down.  So if one AP is 36,44 I don't want another to do 44,36.  ... View more

Thank you so much for the additional information, I had read a lot about all this on your blog too.  So I finally was I believe able to get it working how it should under Flexconnect as well.  It makes sense that AP would remark the frames as Best Effort because it does not know about the application and per Cisco Wireless design it is not keeping those markings.   So with AVC basically we are defining it and being very specific to let the AP know if the Application is "xyz" mark it as voice or video etc.  Couple of things: - Before AVC did the QoS not work from the AP to client? - Even when I marked Facetime as Platinum or Gold (see attached screen shot).  I was thinking I should have gotten the UP value of 5 and 4, but I got like 6 and 5.  I'm thinking that might require some additional configuration tune up.   Bottom line looks like AVC Profiles need to be created and have to define the applications under there in order for this to work properly.  Otherwise AP does not know what to do with it.  Just like we would do it on the LAN side. ...

That is correct I'm trying to play around with FlexConnect AVC to see if that works. ... View more

Thanks for the reply Rasika here are the results: 1- Local mode with Platinum profile assigned to the WLAN (no AVC profile) same results, clients as sa or ta = voice/video but AP as TA it was all Best Effort. 2- Local mode with Platinum profile assigned to the WLAN - Also custom AVC Profile with Facetime in it being marked as Voice I got voice from client to AP and AP to client 3- Local mode with Platinum profile assigned to the WLAN - Also custom AVC Profile with Facetime in it being marked as Video I got voice from client to AP and AP to client. ...

I have 8.2.170.0 running.   NOTE:  I tested this with a Meraki AP and Meraki switch and it seems to be perfect.  Facetime between two iPhones same scenario started with BE and then changed to Voice and Video UP.   BTW I'm not seeing the QoS Map even enabled in the WLC, based on the following document looks like it not only needs to be enabled but configured.  I wonder if that is breaking it and the fact that it is not even enabled not sure what is being applied and its just putting everything in BE bucket.   https://clnv.s3.amazonaws.com/2018/usa/pdf/BRKCRS-2501.pdf   ...

Thank you for that, something is still not right and doesn't make sense with the AP's then. Tried Facetime with Cisco AP's and couple of other vendors and every time if the AP is a "ta" it shows BE to both clients. Not sure why AP is just disregarding the UP of 5 or 6 from the clients and converting it to 0. ... View more

Thank you Rasika as always awesome blog entry. So these are the newer switches and using the service policy and ACL's instead of using "trust dscp/cos" commands. Even tried it on a port that did not have anything on it such as no "trust dscp/cos" commands and no "service policy" commands and same results which I can understand. Trying to find out why that AP is stripping the UP and converting it to BestEffort. Below are two examples of the ports.   interface GigabitEthernet1/1 switchport trunk native vlan 10 switchport trunk allowed vlan 10,20 switchport mode trunk switchport nonegotiate logging event trunk-status spanning-tree portfast interface GigabitEthernetX/X switchport access vlan 100 switchport mode access switchport voice vlan 2 switchport port-security maximum 3 switchport port-security switchport port-security aging time 2 switchport port-security aging type inactivity no snmp trap link-status auto qos voip cisco-phone storm-control broadcast level 10.00 storm-control action trap qos trust device cisco-phone spanning-tree portfast spanning-tree bpduguard enable spanning-tree guard root service-policy input AutoQos-VoIP-Input-Cos-Policy service-policy output AutoQos-VoIP-Output-Policy Secondly I've read that with Access Port I should trust DSCP and with Trunk Port CoS. However seems like trusting DSCP would be a better way to go if I want to change priority of management and user traffic even if it is a trunk port. On the other hand Trusting DSCP on the port will disregard what the AP is imposing from the WLAN Profile? Did I read that right? So basically if I have under WLAN Profile --> Platinum switch will disregard what the client sent it as and what the AP put it under and can completely change it? Thank you. ... View more

It is just a simple SSID with QoS Profile of Platinum assigned to it. ... View more
