To explain the effect of STP & Pseudo VLAN on the wireless clients, we will compare 3
separate scenarios.
Scenario #1 – (No STP, No Pseudo VLAN)
Referring to the illustration below, if the Spanning Tree Protocol (STP) and Pseudo
VLAN are not implemented in a network, all clients (Notebook#1, #2, #3 & #4,) can
access to one another, resulting low level of data security. If redundant paths were found
in this network, broadcast packets will be duplicated and forwarded endlessly resulting
in a broadcast storm.
