www.dell.com | support.dell.com FTOS supports three other variations of Spanning Tree, as shown in Table 44. Table 32-1. FTOS Supported Spanning Tree Protocols Dell Force10 Term Spanning Tree Protocol Rapid Spanning Tree Protocol Multiple Spanning Tree Protocol Per-VLAN Spanning Tree Plus IEEE Specification 802.1d 802.1w 802.1s Third Party Implementation Information • The FTOS MSTP implementation is based on IEEE 802.1Q-2003, and interoperates only with bridges that also use this standard implementation. • MSTP is compatible with STP and RSTP. • FTOS supports only one MSTP region. • When you enable MSTP, all ports in Layer 2 mode participate in MSTP. • On the C-Series and S-Series, you can configure 64 MSTIs including the default instance 0 (CIST). Configure Multiple Spanning Tree Protocol Configuring Multiple Spanning Tree is a four-step process: 1. Configure interfaces for Layer 2. Refer to Configuring Interfaces for Layer 2 Mode. 2. Place the interfaces in VLANs. 3. Enable Multiple Spanning Tree Globally. 4. Create Multiple Spanning Tree Instances.
