Controllerless Networks

I'm setting up an Aruba Instant cluster on an 8 story building, two APs per floor.

 

I've noticed that ARM is choosing Channel 1 for every AP in the cluster.

 

When that happens the clients can no longer connect to the wireless networks. This causes the clients to see many networks on Channel 1.

 

We tried to solve it by manually setting up the channel on every AP. But after a few hours, the channel was reverted to 1 on most APs.

 

Have you experienced this issue before?

What IAP OS version you have installed ?

Are those very close to each other ?

Are users experiencing performance issues?

From the support tab run the ap arm history

We had two APs located per floor, not very close to each other.

 

All of them were running 6.2.0.0-3.2.0.4, the issue was solved after we upgraded to 6.2.1.0-3.4.0.2

Thanks for posting the current status and REMEDY to your observed issue.

I am experiencing the same issue with 6.4.4.3-4.2.2.0_53034. Does anyone know if it can be fixed with an upgrade again?

Please be specific AND show screenshots of what you are talking about.

I have two IAPs 205 deployed in the same building floor, relatively close to each other.  The issue im presenting is that both AP's are in the same channel. 

 

 

 

Your photo is so blurry, that I cannot see anything.

 

SSH into each AP and type "show ap arm rf-summary" to see why they would be on the same channel:

 

 

show ap arm rf-summary

You might want to consider disabling "Client Aware".  An access point will not change channels if clients are associated and passing traffic, if this is enabled.  If there is severe interference, it will change channels.

 

Which channel are all of your access points on?

 

Thanks,

 

Right now they're in the following channels:

 

2.4: Ch. 11

5: Ch. 36+

 

If Client aware is enabled it should change channels when there is no traffic, correct?

Your previous output said that APs current ARM assignment is 149+ and 11.

 

Client Aware enabled would not change channels if there is user traffic, yes.  Disabling it could speed things up, if things need to even be sped up.

Yes,

 

Those are the channels I selected manually for one of the AP's because it wouldn't change automatically!

 

I plan on change it back to ARM once I get this sorted out :)
