Configuring PVST+ Support

PVST+ support is automatically enabled when the port receives a PVST BPDU. You can manually enable the support at any time or disable the support if desired.

A port that is in PVST+ compatibility mode due to auto-detection reverts to the default multiple spanning tree mode when one of the following events occurs:

  • The link is disconnected or broken
  • The link is administratively disabled
  • The link is disabled by interaction with the link-keepalive protocol

This allows a port that was originally interoperating with PVST+ to revert to multiple spanning tree mode when connected to a RUCKUS device.
