Hi, on those AP's the beam forming is hardware based, and its always enabled. no need to have it disabled. the 1600 has this command since its software based. to check if beam forming is enabled on the AP, get something like this “from your show tech” "BF "which means Beam Forming is working: OFDM : LBF : HT20-7 : HT20-15 : HT20-23 : HT40-7 : HT40-15 : HT40-23 : N-HT40 Dup : HT20 BF-7 : HT20 BF-15 : HT20 BF-23 : HT40 BF-7 : HT40 BF-15 : HT40 BF-23 : HT20 STBC-7 : HT40 STBC-7 : 2 2 2 2 : 2 2 2 2 2 2 2 2 : 2 2 2 2 2 2 2 2 : 2 2 2 2 2 2 2 2 : 2 2 2 2 2 2 2 2 : 2 2 2 2 2 2 2 2 : 2 2 2 2 2 2 2 2 : 2 2 2 2 2 2 2 2 : 2 2 2 2 2 2 2 2 : 2 2 2 2 2 2 2 2 : 2 2 2 2 2 2 2 2 : 2 2 2 2 2 2 2 2 : 2 2 2 2 2 2 2 2 : 2 2 2 2 2 2 2 2 : 2 2 2 2 2 2 2 2 : 2 2 2 2 2 2 2 2 : 2 2 2 2 2 2 2 2 : 2 2 2 2 2 2 2 2 : 11 its also documented here https://tools.cisco.com/bugsearch/bug/CSCuo25989/?reffering_site=dumpcr

Hi, to make it simple, just get a debug client <MAC> and look into the logs after the EAP challenges, you should see the following -access-accept or -access reject or -access challenge if you get access-accept, then everything is fine with the .1x if you get reject, check your AAA server logs and the supplicant configuration if the issue appears after access accept and the clients disconnect the logs might show you why "you need a timestamp" for the .1x exclusion, it seems that the client is using wrong credentials multiple times and the WLC block it to prevent the AAA queue to be full.

Hi, what the difference between a static interface and dynamic interface is static interface are the vital interfaces for the WLC "management, Service port, Virtual interface, the dynamic interfaces are to define VLANs for the SSID's and also what ap auto management is. you need this one to make the L3 communication between the WLC and the AP Also when do you use LAG? you use LAG to have redundancy if the physical link went down, if you don't want to use LAG, just set each interface to have backup port in case of failure. for your issue, to broadcast SSID's you need to make the AP's join the WLC first, for that: -what is the WLC software? -what are the AP models? after the AP's are joined, just create AP groups and assign the SSID's to each specific AP.

Hi Ivan, Once SSO is enabled, the Standby WLC can be accessed via console connection, SSH/Telnet on service port, and SSH on the redundant management interface. http://www.cisco.com/en/US/products/ps10315/products_tech_note09186a0080bd3504.shtml to force manual switchover, try this redundancy force-switchover and a side note, go to 7.4.121.0 if you have HA.

Hi, do the audit from controller tab on the PI, then pull the configuration on the WLC to the PI when you are prompted to do so.

Hi, currently wlc1 holds 200 adder licenses and wlc2 holds 100 adder licenses. Both have a base license for 300 AP's. It's best practice to transfer the 100 adder licenses from wlc2 to wlc1 as this will be the primary unit in HA setup? I'm afraid to loose the 100 licenses and it's no big deal to transfer them in advance you have 7500 WLC, which means you dont have a license, your WLC supports RTU and you can add up to 6000 AP count instantaneously http://www.cisco.com/en/US/prod/collateral/wireless/ps6302/ps8322/ps11635/qa_c67-713536.html Regarding the question above: AP's discover the WLC's through option 43 delivered in the DHCP offer in our setup. Both management interfaces are encoded in the HEX value. Once I switch to HA, I only need to include 1 management IP in the HEX value as this IP will be transfered in case of failure to the standby WLC? Yes. The interface that is configured for Dynamic AP management is different than the management interface. Once I switch to HA, I will only have 1 IP address for the ap-management interface in the HA setup? You can configure another dynamic AP manager interface. or move to the management to be the ap manager. regarding the redundancy port: It can now be transported over L2, but it is still best practice to connect both WLC's with a direct cable? on 7.5, you can use L2 VLAN and not necessary to be connected directly. both WLC's are managed via a Cisco Prime Infrastructure appliance (upgraded to 1.4 to support 7.5) Is it best to convert to HA via Prime? I prefer CLI but I don't want Prime to get out-of-sync with the running WLC config. I'm also wondering what will "happen" with the 2nd WLC once HA conversion is complete. It will be unreachable for Prime I guess so it needs to be removed to avoid confusion? i prefer CLI, when the conversion is done, the PI can monitor the pair "as a HA pair " bottom line, the HA will just combine your two devices to be one "in prespective of the other network devices" please let me know if you need anything else. Only the redundancy-management interface will need to be configured with the peer-address? What is the behaviour for the other interfaces (eg: management interface, ap-management interface, ...)? There is only 1 IP in the HA config and it will be transfered to the other wlc in case of switchover yes, both will have the same interfaces addresses

Hi, the AP you are testing with has never joined a WLC before? remove that DNS entry temporary, and check for the master controller option on the old WLC. can you post a console output from the AP while its trying to join?
