Enabling STP/RSTP

Enabling STP/RSTP

Context

After STP/RSTP is enabled on a ring network, spanning tree calculation starts immediately on the network. Configurations on a switching device, such as the device priority and port priority, affect spanning tree calculation. Any change to the configurations may cause network flapping. To ensure rapid, stable spanning tree calculation, perform basic configuration on the switching device and its ports before enabling STP/RSTP.

Procedure

  • Enable STP/RSTP on a switching device.
    1. Run:

      system-view

      The system view is displayed.

    2. Run:

      stp enable

      STP/RSTP is enabled on the switching device.

      By default, STP/RSTP is enabled on a industrial switch router.

  • Enable STP/RSTP on an interface device.
    1. Run:

      system-view

      The system view is displayed.

    2. Run:

      interface interface-type interface-number

      The interface view is displayed.

    3. Run:

      stp enable

      STP/RSTP is enabled on the interface.

      By default, STP/RSTP is enabled on the interface.

Follow-up Procedure

When the topology of a spanning tree changes, the forwarding paths for associated VLANs are changed. Switching devices need to update the ARP entries corresponding to those VLANs. Depending on how switching devices process ARP entries, STP/RSTP convergence mode can be fast or normal.

  • In fast mode, ARP entries to be updated are directly deleted.

  • In normal mode, ARP entries to be updated are rapidly aged.

    The remaining lifetime of ARP entries to be updated is set to 0 to immediately age the ARP entries out. If the number of ARP aging probes is greater than 0, the switching device performs aging probe for these ARP entries.

Run the stp converge { fast | normal } command in the system view to configure the STP/RSTP convergence mode.

By default, the normal STP/RSTP convergence mode is used. The normal mode is recommended. If the fast mode is used, ARP entries will be frequently deleted, causing a high CPU usage (even 100%). As a result, network flapping will frequently occur.
