The Dell Networking OS supports three other variations of spanning tree, as shown in the following table.
Table 66. Spanning Tree Variations Dell Networking OS Supports
Dell Networking Term IEEE Specication
Spanning Tree Protocol (STP) 802 .1d
Rapid Spanning Tree Protocol (RSTP) 802 .1w
Multiple Spanning Tree Protocol (MSTP) 802 .1s
Per-VLAN Spanning Tree Plus (PVST+) Third Party
Implementation Information
• The Dell Networking OS implementation of PVST+ is based on IEEE Standard 802.1w.
• The Dell Networking OS implementation of PVST+ uses IEEE 802.1s costs as the default costs (as shown in the following table). Other
implementations use IEEE 802.1w costs as the default costs. If you are using Dell Networking systems in a multivendor network, verify
that the costs are values you intended.
Congure Per-VLAN Spanning Tree Plus
Conguring PVST+ is a four-step process.
