AP load balancing Wing
« on: April 09, 2014, 10:09:49 AM »
Hello, I am rather new to large scale wireless networking and I am having a few troubles getting load balancing to work on motorola wing AP71XX and was wondering if anyone could help me out?

maybe listing what steps i need to follow and configuration i need before hand? I will say now these Wing devices are the only motorola and generally standard devices on the network, so just assume they link up on lan via a switch with a random linux dhcp server nothing else can be added to this network

any help?? :)

need more information to discuss, if there is a controller or not? it's important.

when you mentioned the load balance, what did you mean?

I would rather ask: is that really a High Density Deployment? I.e. are there APs each every ~5 meters? I would suggest you to read first Client Load Balancing guide. Otherwise there is no point to implement CLB and waste any time on that.

I mean load balancing between two access points, if the ratio of one access point is higher then the other push clients on to the other AP...

I do not have a controller, though if possible I can set a virtual one, but I am at a loss with this as the documentation is not very useful to me

the APs will be around 5-15 meters apart

well, you can cut out deployment without any controller, even w/o Virtual Controller, as APs have to communicate with each other, and they do that via MiNT protocol, which is disabled if you configure each AP as standalone.
Second point, you can always do bandsteering (assuming that is no VOIP deployment), that will force dual band clients to prefer 5GHz band. For that you only need to enable "client-load-balancing" under wlan config and "load-balancing balance-band-loads" under AP profile, nothing else. Regarding Channel load balancing and AP load balancing -> client really have to hear from at least 3 APs at the same time with good RSSI level, so load balancing algorithm could do its ratio balancing between APs, channels, etc.

Dont try anything other than bandsteering in non-high density deployments.

thank you these are some good tips, a bit more detail if you can drop any more hints...

I have 3 APs in something simular to the size of a church hall but a little more narrow with a max of around 180 users connected to the APs...but lets assume im in a very tiny room right now :P  I thought i managed to get it working on two at one point where it would balance between APs based upon ratio. for every 1 higher it would push over but 3rd sets of tests were inconclusive...

Please can you post your config? I assume all 3 APs are adopted to VC now.

sadly I cannot post the config :( and no they havent adopted I think this may be my problem, I have only one account of them even seeing each other... do you have any basic configs I could possibly use as a test? that only use the CWAPs? I am good at reverse engineering its mostly how i learn

Sample configs are inside client load balancing how to(available here in the forums).
Be sure that all APs have MiNT enabled, either VLAN or IP(since these are only 3 APs, I assume they are on the same broadcast domain, so go to each AP and enable "mint mlcp vlan"). Then choose one AP to be Virtual Controller, after a while it will adopt other two, assuming they are the same model type.
Verify adoption via " show adoption status" on VC AP. After this is done, everything must be configured only from VC.

I DID IT .... I used a VC and DHCP, though the only issue is I need them all to have their own static addresses (all 3 APs ) but the two children keep getting the same ip as the parent? which is rather annoying btw any suggestions ??

most probably because you set those static IP addreses on the profile level, not in the device overrides.. so all 3 APs will get one static IP from the profile. Without lookig at the config I can only guess

yes you are right I did, though I dont know where else i can set these? I thought this was the only way... point me in the right direction? I see vlans in the device profile with static IPs for management and public

in cli:

en
conf t
apxxxx <AP MAC>
interface vlan <index>
ip address <x.x.x.x/x>
com wr

in GUI if its Virtual Controller go to device overrides tab on the VC, you will see all adopted APs in the config by their MAC addresses.
