10.1 Introduction
Spanning Tree Protocol (STP) is IEEE standard (802.1d) that avoids looping in the network while maintaining
multiple Ethernet bridges. STP can avoid loops by placing ports in forwarding state or in blocking state to establish
redundant paths. When STP is enabled, the switch will execute STP Bridge Protocol Data Unit (BPDU) packets as
below:
•
If the port is in Block-N-Listen State or Learning State, the BPDU packet is forwarded to the CPU, other
packets are discarded.
•
If the port is in the Forwarding State, the BPDU packet is forwarded to the CPU, all other packets are normally
forwarded based on the switch engine decision.
