Fist clinet IP: 10.76.42.9  connect to SSID WIFI
Second client IP: 192.168.33.106 connect to SSID Smart-Phone
Phone MAC address : f409-d8a4-1434
Laptop MAC address: 9465-9C35-BFA6
Try to ping the clint from the AC there is jitter:

transparent.gif Root Cause

The network for access SW is not stable, need to configure access switch with stp bpdu-protection and stp edged-port enable , that is a security feature designed to protect the active STP topology by preventing spoofed BPDU packets from entering the STP domain. In a typical implementation, BPDU protection would be applied to edge ports connected to end user devices that do not run STP. If STP BPDU packets are received on a protected port, the feature will disable that port and alert the network manager.

transparent.gif Solution
Applay bpdu protection in system view:
<Access-Switch>sys
[Access-Switch]stp bpdu-protection


Applay stp edged-port enable in all port of all access switch, will use group-member to
make it fast:
[Access-Switch]display port-group
1

There are alredy groub groub 1:
[Access-Switch]port-group 1
