Usage Guidelines

Usage Scenario

If a device has many interfaces, running the display stp command displays a large amount of information, and it is difficult to find wanted information about the spanning trees of the root and local bridges.

To view detailed information about the spanning trees of the root and local bridges, run the display stp bridge command.

Example

The actual command output varies according to the device. The command output here is only an example.

# Display detailed information about the spanning tree of the root bridge in MSTP process 1.
