Switch(config-ge1/2)#spanning-tree mst link-type shared

8.2.6 PORTFAST related configuration

1) Port Fast

Port Fast immediately transfers a access or trunk port from the blocking state to the

forwarding state, bypassing the listening and learning states. You can connect to a separate

workstation and server using Port Fast, which allows these devices to connect to the network

immediately without waiting for spanning tree to converge。

Configure a port for fast port：

Switch#configure terminal

Switch(config)#interface <if-name>

Switch(config)#spanning-tree mst portfast

2) BPDU Filtering

BPDU filtering can be opened globally based on switches or based on each port, but their

characteristics are different。

In the global layer, you can use the spanning-tree MST portfast bpdu-filter command to start

the BPDU filtering function on the port of the portfast bpdu-filter default state。

In the port layer, you can open BPDU filter on any port with spanning-tree MST portfast

bpdu-filter enable。

This function prevents port fast ports from receiving or sending BPDU。

Configuring BPDU Filtering

In global configuration mode：

Switch#configure terminal

Switch(config)# spanning-tree mst portfast bpdu-filter

Under the interface configuration mode：
