xStack DES-6500 Modular Layer 3 Chassis Ethernet Switch User Manual
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.
To configure port trunking, open the Link Aggregation folder and click on the Link Aggregation Configuration
hyperlink in the Configuration folder to bring up the Link Aggregation Group Entries table:
