RSTP provides the structure on which the MST operates, significantly reducing the time to reconfigure the active topology of a network when its physical topology or configuration parameters change. RSTP selects one switch as the root of a spanning-tree-connected active topology and assigns port...
spanning-tree [mst <instance-id>] priority <value(0-61440)> no spanning-tree [mst <instance-id(1-64)>] priority Parameter Description mst <instance-id>- Configures the ID of MSTP instance already created in the Switch. This value ranges between 1 and 64. The special ...
Do not configure an access switch as the spanning-tree primary root. Use the diameter keyword, which is available only for MST instance 0, to specify the Layer 2 network diameter (that is, the maximum number of switch hops between any two end stations in the...
An MST region contains two types of spanning tree instances: an Internal Spanning Tree Instance (IST) and Multiple Spanning Tree Instances (MSTI). IST is the default spanning tree instance in MST regions; and is always zero. It gives a root switch to the region that contains all VLANs ...
