Configuring Spanning Tree Spanning Tree
In RSTP/MSTP, the port status includes: Discarding, Learning and Forwarding. The Discarding
status is the grouping of STP’s Blocking, Listening and Disabled, and the Learning and Forwarding
status correspond exactly to the Learning and Forwarding status specified in STP.
In TP-LINK switches, the port status includes: Blocking, Learning, Forwarding and Disconnected.

Blocking
In this status, the port only receives BPDUs. The other packets are dropped.

Learning
In this status, the port receives and sends BPDUs. It also receives the other user packets to update
its MAC address table, but doesn’t forward them.

Forwarding
In this status, the port receives and sends BPDUs. It also receives the other user packets to update
its MAC address table, and forwards them.

Disconnected
In this status, the port is enabled with spanning tree function but not connected to any device.
Path Cost
The path cost reflects the link speed of the port. The smaller the value, the higher link speed the
port has.
The path cost can be manually configured on each port. If not, the path cost values are
automatically calculated according to the link speed as shown below:
Table 1-1 The Default Path Cost Value
Link Speed Path Cost Value
10Mb/s 2,000,000
100Mb/s 200,000
1Gb/s 2,000
10Gb/s 200
Root Path Cost
The root path cost is the accumulated path costs from the root bridge to the other switches.
When the root bridge sends its BPDU, the root path cost value is 0. When a connected switch
