ICP DAS USA MSM-6226 user manual Mstp Configuration, Status

3-15. MSTP Configuration

The implementation of MSTP is according to IEEE 802.1Q 2005 Clause 13 – Multiple Spanning Tree Protocol. MSTP allows frames assigned to different VLANs to follow separate paths, each based on an independent Multiple Spanning Tree Instance (MSTI), within Multiple Spanning Tree (MST) Regions composed of LANs and or MST Bridges. Proper configuration of MSTP in an 802.1Q VLAN environment can ensure a loop-free data path for a group of vlans within an MSTI. Redundant path and load balancing in vlan environment is also achieved via this feature.A spanning tree instance called CIST(Common and Internal Spanning Tree) always exists . Up to 64 more spanning tree instances (MSTIs) can be provisioned.
