The Dell Networking OS supports only one spanning tree instance (0). For multiple instances, enable the multiple spanning

tree protocol (MSTP) or per-VLAN spanning tree plus (PVST+). You may only enable one flavor of spanning tree at any one

All ports in virtual local area networks (VLANs) and all enabled interfaces in Layer 2 mode are automatically added to the

spanning tree topology at the time you enable the protocol.

To add interfaces to the spanning tree topology after you enable STP, enable the port and configure it for Layer 2 using the
