1132BConfiguration prerequisites
Before configuring a spanning tree, you must determine the spanning tree protocol to be used (STP, RSTP,
or MSTP) and plan device roles (the root bridge or leaf node).
1133BConfiguration restrictions and guidelines
• The spanning tree configurations made in system view take effect globally. Configurations made in
Ethernet interface view take effect on the interface only. Configurations made in Layer 2 aggregate
interface view take effect only on the aggregate interface. Configurations made on an aggregation
member port can take effect only after the port is removed from the aggregation group.
• After you enable a spanning tree protocol on a Layer 2 aggregate interface, the system performs
spanning tree calculation on the Layer 2 aggregate interface but not on the aggregation member
ports. The spanning tree protocol enable state and forwarding state of each selected member port
is consistent with those of the corresponding Layer 2 aggregate interface.
• Though the member ports of an aggregation group do not participate in spanning tree calculation,
the ports still reserve their spanning tree configurations for participating in spanning tree
calculation after leaving the aggregation group.
