Displaying VBST Running Information and Statistics

Displaying VBST Running Information and Statistics

Context

You can view the VBST running information and statistics on VBST BPDUs. If the number of topology change times increases, network flapping occurs.

Procedure

  • Run the display stp [ vlan vlan-id ] topology-change command to check VBST topology change statistics.
  • Run the display stp error packet command to check the number of received error packets and the content of recently received error packets.
  • Run the display vbst bpdu-statistics [ vlan vlan-id ] [ interface interface-type interface-number | slot slot-id ] command to check BPDU statistics.
  • Run the display vbst port-vlan statistics command to check statistics on the PV number of VBST.
  • Run the display stp [ vlan vlan-id ] [ interface interface-type interface-number | slot slot-id ] tc-bpdu statistics command to check statistics on TC or TCN BPDUs on the VBST-enabled interface.
