Important Points to Remember
• RSTP is disabled by default.
• FTOS supports only one Rapid Spanning Tree (RST) instance.
• All interfaces in VLANs and all enabled interfaces in Layer 2 mode are automatically added to the
RST topology.
• Avoid using the
range command to add a large group of ports to a large group of VLANs; adding a
group of ports to a range of VLANs sends multiple messages to the RSTP task. When using the
range
command, Dell Force10 recommends limiting the range to 5 ports and 40 VLANs.
Configure Interfaces for Layer 2 Mode
All interfaces on all bridges that will participate in Rapid Spanning Tree must be in Layer 2 and enabled.
