6.6.1.5 (Optional) Setting a Priority for a Port. Huawei AR550 Series, AR530 Series

Huawei AR530&AR550 Series Industrial Switch Routers

Configuration Guide - Ethernet Switching 6 STP/RSTP Configuration

Procedure

Step 1 Run: system-view

The system view is displayed.

Step 2 (Optional) Run: stp pathcost-standard { dot1d-1998 | dot1t | legacy }

A path cost calculation method is specified.

By default, the IEEE 802.1t standard ( dot1t ) is used to calculate the path costs.

All switching devices on a network must use the same path cost calculation method.

Step 3 Run: interface interface-type interface-number

The view of an interface participating in STP calculation is displayed.

Step 4 Run: stp cost cost

A path cost is set for the interface.

l When the Huawei calculation method is used, cost ranges from 1 to 200000.

l When the IEEE 802.1d standard method is used, cost ranges from 1 to 65535.

l When the IEEE 802.1t standard method is used, cost ranges from 1 to 200000000.

6.6.1.5 (Optional) Setting a Priority for a Port

Context

In spanning tree calculation, priorities of the ports in a ring affect designated port election.

To block a port on a switching device, set a greater priority value than the default priority value for the port.

Procedure

Step 1 Run: system-view

The system view is displayed.

Step 2 Run: interface interface-type interface-number

The view of an interface participating in STP calculation is displayed.

Step 3 Run: stp port priority priority

A priority is set for the interface.
