Usage Guidelines

Usage Scenario

To check statistics on BPDUs on the switch running VBST, run the display vbst bpdu-statistics command.

Prerequisites

In VBST, if NAC authentication is configured but user authentication fails on a port that is configured as an edge port and is in Active state, information about the port is not displayed.

Example

# Display VBST BPDU statistics in VLAN 2.

<HUAWEI> display vbst bpdu-statistics vlan 2
