Link Aggregation - D-Link DGS-3427 User Manual

xStack DGS-3400 Series Fast Ethernet Switch
Load balancing is automatically applied to the ports in the aggregated group, and a link failure within the group causes the
network traffic to be directed to the remaining links in the group.
The Spanning Tree Protocol will treat a link aggregation group as a single link, on the switch level. On the port level, the
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.
