Hi you must use the file type "run-config" when using the transfer upload method, or get it through SSH, "sh run-config" with config paging disabled The program does not support processing of config backups (startup config). regards

Hello Clayton WLCCA uses the standard Microsoft installer, you should be able to go to control panel, programs and applications, and remove it from there, then install the new version regards

New version for WLCCA 4.4.6 Added copy cell options for all tables Fixes for WLAN key caching 802.11r FT state Fix for Roaming prediction tool for 5GHz/8.2+ files Minor other fixes

Adding on top, it works for 2., but fails for 5 GHz problem fixed, it will be on next WLCCA post regards

Hi Pietro as discussed over email: Basically: The AP order in one file, does not match the other, this means that AP21 is #51 in one file, and #54 in another When you change the selected config set, the roaming prediction tool will use the AP ID/list from the 8.1, with the AP order for the file in 8.2, causing that all the nearby information is used from the wrong AP Solution: If using the roaming prediction tool, load only the file you are interested, and select the Aps from there. Tested with 8.2 file, it works

HI Pietro Could you send me unicast the initial and new sh run files, and show me the problem you see there? Thanks.

Hi Aaron Yes, we are planning on export feature for future release regards

Hi Anthony thanks for your suggestion. I will incorporate the feedback on future version of the tool regards

Hello All new WLCCA version 4.4.4 is available. Changes: Fixes for several parsing errors Adds AP error message for invalid RRM power level in radio

Javier Contreras · ‎08-30-2017

HI >Now, with the 5520/8540 this formerly supported scenario is deprecated and there is no officially supported solution for that, except deploying WLCs in the remote locations. well... for 5520, we added support for multicast-unicast scenario in I think, 83MR2 (if I am not mistaken) it is only supported on limited size networks (AP count), as the multicast frame replication simply can't scale to the number of APs that those platforms can support on a fully loaded scenario So there is a solution for 5520 as long as the network is not large regards

Javier Contreras · ‎08-30-2017

Hi Johannes Here the distinction is mostly on Supported=Tested, so let's go by parts. Basically: Flex with multicast-unicast mode central switching, is supported (because it is tested) scenario. Flex with multicas-multicast mode, central switching, is not tested, thus not officially supported. Does it work? yes, it should, as I am not aware of any explicit blocking point at AP level for this not to work, but if a bug is found on this specific topology/feature combination, it would be treated as best effort fix. Why it is not a tested scenario: because few, if any, customers would have a WAN scenario supporting multicast routing, so this has never been a priority to add as specific test case. For local switching, the multicast mode at WLC should not have any impact, as the traffic forwarding is handled by AP directly on the VLAN. There are test scenarios to validate that WLC should not consume/generate multicast for those vlans on flex AP local switching scenarios (if WLC sends multicast to them from the central site, that is a bug, and must be fixed)

hi Felix the version 4.4.1 introduced a parsing problem (it skipped a important section of data), which cascaded on multiple checks providing incorrect data so yes, it would be important to migrate to 4.4.3, and report any new issues from that release Thanks for your feedback regards
