Roaming issue in RFS cluster

Team, I have a following roaming /disconnenction problem at customer site:

 

HW config:

 

2x RFS6x – active/standby cluster config sharing 8+8 licenses WING 5.4.4

16x Moto AP650

2x Cisco SG300-24p POE switch

 

6x MC9190-CE6, Fusion v3.2.018.

 

ETH switches are connected with 1Gb optical connection

 

Both RFS6k are connected to same switch

7x AP650 are connected to the switch where the RFS6ks are connected to

9x AP650 are connected to the second switch

 

The problem we're having is that when MC9190 roams between the two ETH switches we are experiencing disconnections from the WMS system.

There is no special config on the RFS6k, using only VLAN1 and one WLAN with WPA2-AES PSK.

Do you have any tips why the disconnection happens while roaming between AP's which are connected to two separate  RFS? Thanks Roland

You didn't mention what application was running on your MC9190's.  In my experience it is possible to have issues with MC9190's and other devices if you leave Layer 2 stateful packet inspection enabled in the firewall.  This is definitely a problem if you are performing SSH / Terminal Emulation with the MC9190.  It is most noticed when the device roams.  I don't know if this is your issue, but I would consider it a good item to test.  Following are the commands to implement in 5.4.x firewall-policy default  no stateful-packet-inspection-l2
