Is there any intention for this release to have the various bug fixes from the current build integrated into it?

Also are there any plans to implement the fixes for DFS related issues that are fixed in the build into 8.0mr2, specifically:

CSCuq86252 / CSCuq86269



Cisco Employee

Hi Will


most of the fixes on will be integrated here, this first beta is "half way"  on the total bug count planned for the release. Not all is expected to move into MR2 

CSCuq86269 in particular, is still under evaluation  for 8.0 inclusion (there are some steps needed)





Hello Javier,

If it's a known bug, why wouldn't be integrated into MR2?! It doesn't make sense. All known bugs that have been resolved on the "Escalation" builds should be on MR2. That would avoid more TAC cases to be opened.


Cisco Employee

hi Gustavo


Things are more complex that just that. Escalation builds allow us quite a large freedom to handle what is included or not on them. CCO builds have a very strict commit procedure,  plus a time window for posting, so not all issues may be included until some requirements are met and timelines can be satisfied

Just to add more details: In this particular bug, as it is a DFS radio change, it has to pass compliance certification on each radio firmware version that it is included, so tests done for 7.4  (it is included already in upcoming, need to be totally re-done for 8.0, and they take 2 weeks.

I do a continuous evaluation on what goes into MR releases, and  we try as much as possible to  include fixes to lower any potential TAC cases. if a known issue is evaluated as pervasive and has a viable fix, we try to include it




Hello Javier,

I got your point. I didn't express myself clearly (I think). What I meant was that all known bugs that were fixed on "Escalation" builds for the same trail (read 8.0.110.x) should be commited to be on MR2. I know that the code may vary from trail to trail (read 7.6 to 8.0) and tests should be done.

Anyway, thanks for the information. I didn't know all these steps behind the process.

Best Regards

It appears that most of the fixed bugs here are also fixed in 8.1; are you aware of any critical ones that didn't make it into the release?


Obviously 8.1 carries the risk of exciting new bugs.. but, well, shiny!  ;)

Rising star

Thank you Javier for sharing latest release 8.0.115.x availability - 8.0MR2 Beta with community user, appreciated +5 :-)

Cisco Employee

hi Nate


All of the critical needed fixes in 8.0 were carried over to 8.1 release



Community Member

Great, thanks!

I'll let bake for a week or so probably, and if all is well, start the rollout process for 8.1.  :)


Thanks for sharing the information and new releases!


Question about which release is recommended:

Is advisable over


For example I can't find

CSCus87673 - 3700 AP 5ghz Radio Reset

in the release notes for, while it is already in


Thanks in advance!

Cisco Employee

Hi Bart


8.0.110.x is 8.0MR1 Escalation branch, and as such, it follows a more aggressive bug commit process

Customers are advised to move to 8.0MR2 official release ( when it is available in CCO, unless they are explicitly affected by a bug fixed in escalation code


Until 8.0MR2 is in CCO, the recommendation would be to use either 8.0.110.x or 8.0.115.x (this beta), as both branches have the same 8.0 critical bugs fixed


For customers with special needs/bugs reported, we will continue to support 110.x esc then, 120.x esc for additional bug fixes, until 8.0MR3 ( future release is preparared


Community Member

Hi Javier,

Can you confirm for me whether the 3602i (-E reg domain) received any DFS changes in - it seems we are still getting stung with a large volume of DFS hits in a large public venue when there are lots of devices on the network.





Cisco Employee

hi Will


we included fix for 2600/3600 families on 8.0MR2, that should improve around 10-30% on the sites that due to RF conditions may generate DFS hits


There is a second fix we are working in, that should improve a lot the rate, please send me private message  and I can work with you on details about it




Any dates for when MR2 will post?  The last I heard was by the end of June.




I have tried to escalation but didn't work so I though I post in this..


Controller: 5508

AP: 1142 and 2702i


Regularity Domain: NZ


I have received couple of universal domain access points and to support this in current environment I have to upgrade current Airos to 8.0.110.x  or 8.0.115.x or


Almost all AirOS has the critical bug with the DDos attack.


I have following questions,


  • Which one is the best and stable software I can use for this environment. ?
  • Do I have to upgrade IOS on the AP to go with 8.1 AirOs?
  • is too new to upgrade


any suggestion which one is the best AirOs to upgrade will be appreciated.
