Scenario 8: Establishing access with vPC enabled across the Cisco Nexus 5010 switches

In this section, we provide an overview of establishing access with

vPC enabled across Cisco Nexus 5010 switches. vPC, or Virtual

PortChannel, is a Cisco technology that allows multiple switches to

present themselves as one switch, combining link aggregation with

switch redundancy. This allows for multiple-port link aggregation

across switches. In our example scenario, each Dell PowerConnect

M8024 switch maintains a 4-port link aggregation with the Cisco

switches, 2 ports in each switch. We provide detailed instructions in

Appendix A.

1.On each Dell PowerConnect M8024 switch, enter the Internal Port VLAN configuration screen, select a port, and change the default Untagged VLAN (we changed ports 1/xg1 and 1/xg8 to VLAN 101).

2.On the each Cisco Nexus 5010 switch, set up the vPC domain and keepalive ports, and create the PortChannel for the downstream switch (the Dell PowerConnect M8024 switch).

3.Cable the two Cisco Nexus 5010 switches together using the peer links you configured.

4.Cable the Cisco Nexus 5010 switches to the Dell PowerConnect M8024 switch. The Dell PowerConnect M8024 switch will automatically make a LAG with the Cisco Nexus 5010 switches and treat the two switches as one.

Figure 10 illustrates the completed configuration for Scenario 8.
