D-Link DES-3250TG Standalone Layer 2 Switch The Spanning Tree Protocol will treat a link aggregation group as a single link. STP will use the port parameters of the Master Port in the calculation of port cost and in determining the state of the link aggregation group. If two redundant link aggregation groups are configured on the switch, STP will block one entire group - in the same way STP will block a single port that has a redundant link. Figure 6- 13.
