Configuration restrictions and guidelines

If BPDU guard is disabled, a port set as an edge port will become a non-edge port again if it
•
receives a BPDU from another port. To restore the edge port, re-enable it.
• If a port directly connects to a user terminal, configure it as an edge port and enable BPDU guard
for it. This enables the port to transit to the forwarding state quickly while ensuring network security.
You cannot configure edge port settings and loop guard on a port at the same time.

Configuration procedure

To configure edge ports:
Step
1. Enter system view.
2. Enter interface view or
port group view.
3. Configure the current
ports as edge ports.

Configuring path costs of ports

Path cost is a parameter related to the rate of a port. On a spanning tree device, a port can have different
path costs in different MSTIs. Setting appropriate path costs allows VLAN traffic flows to be forwarded
along different physical links, achieving VLAN-based load balancing.
You can have the device automatically calculate the default path cost, or you can configure the path cost
for ports.
Specifying a standard for the device to use when it calculates
the default path cost
CAUTION:
If you change the standard that the device uses to calculate the default path costs, you restore the path
costs to the default.
You can specify a standard for the device to use in automatic calculation of the default path cost. The
device supports the following standards:
dot1d-1998—The device calculates default path costs for ports based on IEEE 802.1d- 1 998.
•
• dot1t—The device calculates default path costs for ports based on IEEE 802.1t.
legacy—The device calculates default path costs for ports based on a private standard.

All ports are non-edge ports
by default.
