Scenario 7: Setting up a straight-through topology with LAG failover

In this section, we provide an overview of setting up a straight-

through topology with LAG failover. Simple Switch Mode LAG failover

allows Dell switches to automatically change from the primary to the

backup LAG in the event of a port failure, reducing potential

downtime. We provide detailed instructions in Appendix A.

1.On the Dell PowerConnect M8024 switch, enter the Port Configuration screen, and change the Lag Role of ports to Secondary (we changed ports 1/xg23-1/xg24 to Secondary).

2.On the Cisco Nexus 5010 switches, create two two-port channel groups with LACP enabled.

3.Connect the cables. The Dell PowerConnect M8024 switch will automatically make a two-port LAG with a secondary backup LAG that it will failover to in the event of a cable or port failure.

Figure 9 illustrates the completed configuration for Scenario 7.
