FTOS Supported Spanning Tree Protocols Dell Force10 Term Multiple Spanning Tree Protocol (MSTP) Per-VLAN Spanning Tree Plus (PVST+) IEEE Specification 802.1s Third Party Implementation Information • The FTOS implementation of PVST+ is based on IEEE Standard 802.1d. • The FTOS implementation of PVST+ uses IEEE 802.1s costs as the default costs (Table 38-2). Other implementations use IEEE 802.1d costs as the default costs if you are using Dell Force10 systems in a multi-vendor network, verify that the costs are values you intended. • You must allocate at least the default minimum amount of Layer 2 ACL CAM space when employing PVST+ on the E-Series. See Configure Ingress Layer 2 ACL Sub-partitions on page 287. • On the C-Series and S-Series, you can enable PVST+ on 254 VLANs. To set up VLANs, see Chapter 53, Virtual LANs (VLAN). Configure Per-VLAN Spanning Tree Plus Configuring PVST+ is a four-step process: 1. Configure interfaces for Layer 2. 2. Place the interfaces in VLANs. 3. Enable PVST+. See page 807. 4. Optionally, for load balancing, select a non-default bridge-priority for a VLAN. See page 807.
