IAP 505 cluster AP checksum error

hello,

 

I just deployed a brand new IAP-505 cluster (controlerless) in version 8.6.0.4 but it is unstable... I explain myself:

 - every AP that is connected on a different switch than the one where is the virtual controler has a log message: AP checksum error

 - when I modify the configuration, the Wifi is completely unstable for about 5 min.

 

here is a quick output of # show log system from the VC

Aug 13 15:56:56 cli[4664]: <341132> <WARN> |AP AP-CH1-04@10.6.12.148 cli| Check sum mismatch for AP-10.6.12.166, slave 28729 vs master 1259, error_cnt 1, recover_sent 6.

the cluster is managed by airwave.

the switches are also Aruba and the network topology is simple ( a simple star). Spanning tree is enable (MST)

 

I'm used to deploy IAP-305 and I never had that kind of issue.

 

Do you have any idea?

 

Thank you for your help

Re: IAP 505 cluster AP checksum error

From what you explain: APs on the same switch as the VC are fine, those on a different switch get out of sync, suggest to me there is something between the switches.

 

Do you see anything in the switch logs, like spanning-tree block?

 

Have not seen this recently, so if there is no further response please reach out to Aruba Support and have them look at it.
