Enable BPDU Filtering globally
The enabling of BPDU Filtering stops transmitting of BPDUs on the operational port fast enabled ports by
default. When BPDUs are received, the spanning tree is automatically prepared. By default global bpdu
filtering is disabled.

Modify Interface Parameters
On interfaces in Layer 2 mode, you can set the port cost and port priority values.
• Port cost is a value that is based on the interface type. The default values are listed in Table 27-2. The
greater the port cost, the less likely the port is selected to be a forwarding port.
• Port priority influences the likelihood that a port is selected to be a forwarding port in case that
several ports have the same port cost.
