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