Configuration restrictions and guidelines

When you configure spanning tree protocols, follow these restrictions and guidelines:
•
An eIRF capable device supports enabling PVST for a maximum of 254 VLANs. An eIRF
incapable device supports enabling PVST for a maximum of 510 VLANs. For more information
about eIRF, see Virtual Technologies Configuration Guide.
•
If both MVRP and a spanning tree protocol are enabled on a device, MVRP packets are
forwarded along MSTIs. To advertise a specific VLAN within the network through MVRP, make
sure this VLAN is mapped to an MSTI when you configure the VLAN-to-instance mapping table.
For more information about MVRP, see
•
To connect a spanning tree network to a TRILL network, make sure the following requirements
are met:
The spanning tree protocol is disabled on the TRILL network.

An edge port is used to connect the spanning tree network to the TRILL network. The edge

port can quickly transit to the forwarding state. This prevents network topology changes
from influencing the TRILL network.
For more information about TRILL, see TRILL Configuration Guide.
•
The spanning tree configurations are mutually exclusive with any of the following features on a
port: service loopback group, RRPP, Smart Link, and L2PT.
•
Configurations made in system view take effect globally. Configurations made in Ethernet
interface view take effect only on the interface. 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. It does not perform
spanning tree calculation 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.
•
The member ports of an aggregation group do not participate in spanning tree calculation.
However, the ports still reserve their spanning tree configurations for participating in spanning
tree calculation after leaving the aggregation group.

Spanning tree configuration task lists

Before configuring a spanning tree, complete the following tasks:
•
Determine the spanning tree protocol to be used (STP, RSTP, PVST, or MSTP).
•
Plan the device roles (the root bridge or leaf node).
