Problems in cluster

Hi guys,

 

I have recently set up a cluster of Instant APs. I lost connection with VC, I don't know the reason. When I got connection again, the following message appear by CLI:

 

a8:bd:27:cc:9a:d2# show log system

Jan 1 08:09:07 KERNEL(a8:bd:27:cc:9a:d2@172.17.12.19): [ 559.175726] aruba_change_channel 667 Waiting for VAP INIT to complete
Jan 1 08:09:09 KERNEL(a8:bd:27:cc:9a:d2@172.17.12.19): [ 561.587753] aruba_change_channel 667 Waiting for VAP INIT to complete
Jan 1 08:09:12 KERNEL(a8:bd:27:cc:9a:d2@172.17.12.19): [ 563.993751] aruba_change_channel 667 Waiting for VAP INIT to complete

 

And it doesn't stop and keep appearing. Right now the master is AP 172.17.12.19.

What does it mean? What command can I issue to see why I lost connection with VC?

Julián

We don't have enough information to understand what is going on here.  Did this work at one time?

Re: Problems in cluster

Hi Colin,

 

I set up a new cluster of 17 IAPs yesterday. After the SSIDs where created and the WLAN was steady, at some point I lost connection with the master AP and VC. After a few minutes I got connection again with the VC (then in another AP acting as a master), but when I accessed the WebUI I realized there were no SSIDs at all, and the only SSID was the "instant". I had to create the SSIDs again. I wonder if there is any command or debug to show the logs about what happened yesterday and why. Customer is asking for that and I don't know if it will happen again.

Re: Problems in cluster

If by accident an AP that had "preferred master" configured is introduced into an existing cluster, it will take over the cluster and overwrite the configuration.  You should make sure that AP that is the VC does not have "preferred master" configured.

Re: Problems in cluster

Hi Colin,

 

Thanks. What about the log message?

 

a8:bd:27:ca:78:4e# show log system

Jan 2 03:09:16 KERNEL(a8:bd:27:ca:78:4e@172.17.12.27): [68967.636740] aruba_change_channel 667 Waiting for VAP INIT to complete

 

It keeps appearing.
