BLADE OS 5.1 Application Guide
114 Chapter 5: Spanning Tree Protocol BMD00113, September 2009
The relationship between ports, trunk groups, VLANs, and spanning trees is shown in Table 12.
Assigning Cost to Ports and Trunk Groups
When you configure a trunk group to participate in a Spanning Tree Group, all ports must have the
same Spanning Tree configuration, as follows:
Port priority
Path cost
Link type
Edge port status
Port Fast Forward status
Assign lower path costs on each member of a trunk group, to ensure the trunk group remains in the
Forwarding state.
