Current setup:
2 x 8540 in HA SSO 8.3.120.0 (2000+ APs)
2 x 8510 in HA SSO 8.5.140.0 (test controller but currently has 150+ APs on it)
Both 8540 and 8510 in the same RF domain.
Recently deployed Cisco 2800s in a new building – APs registered on test WLC8510 controller.
FRA is currently enabled on test controller but we have been surprised with some of the results. So, the plan is to leave FRA enabled globally but turned off on the APs (as per best practice recommendations and which we should have done in the first instance).
We will then look at the information gathered (Monitor -> Access points -> radios -> Dual-band radios) and then manually set XOR radios to 5ghz where appropriate.
However, much of the information, such as COF and Suggested Mode, is listed as 'Unavailable'. FRA operation state is also listed as Down. It appears to be related to the RF leader changing or not always being the same for both 2.4ghz and 5ghz bands.
(Cisco Controller) >show advanced fra status
FRA State........................................ Enabled
FRA Operation State.............................. Down
.............................. (RF group leader for 802.11b/g & 802.11a bands are not same, or 11a DCA mode is not auto)
FRA Sensitivity.................................. high (90%)
FRA Interval..................................... 1 Hour(s)
Service Priority................................. Coverage
Recommendation is to set RF leader to static. However when i set either of the controllers to static and attempt to add the other controller to the RF group, two things happen. Firstly the 'Maximum/Current number of AP' figure changes to 6000/6000 and the IP address of the WLC I’m trying to add to the group as non-leader is listed as Invalid:
Anyone advice on setting RF group leader to static?
Anyone any advice regarding FRA in general, particularly its use in HD versus office spaces?
many thanks,
Ciaran
