STP/RSTP maintenance includes resetting STP/RSTP statistics.

Clearing STP/RSTP Statistics

Context

imgDownload?uuid=83895f31a05b4815859726e

STP/RSTP statistics cannot be restored after being cleared.

Procedure

  • Run the reset stp [ interface interface-type interface-number ] statistics command to clear spanning-tree statistics.
  • Run the reset stp error packet statistics to clears the statistics of error STP packets.

Monitoring the Statistics on STP/RSTP Topology Changes

The statistics about STP/RSTP topology changes can be viewed. If the statistics increase, network flapping occurs.

Procedure

  • Run the display stp topology-change command to view the statistics about STP/RSTP topology changes.
  • Run the display stp [ interface interface-type interface-number ] [ brief ] command to view the spanning-tree status and statistics.

Application Scenarios for STP

STP Application

Loops often occur on a complex network, because multiple physical links are often deployed between two devices to implement link redundancy. Loops may cause broadcast storms and damage MAC address entries on network devices.

STP is deployed on the devices. The devices exchange information to discover loops on the network and block a port to trim the ring topology into a loop-free tree topology. The tree topology prevents infinite looping of packets on the network and ensures packet processing capabilities of the devices.
