How to deploy the Dell M8024 family of switches in a Cisco Nexus network

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.
