Supported vPC Topologies
Cisco Nexus 5000 Series Switch vPC Topology
You can connect a pair of Cisco Nexus 5000 Series switches configured in a vPC directly to another switch
or to a server. Up to 8 interfaces could be connected to each Cisco Nexus 5000 Series switch providing 16
interfaces bundled for the vPC pair. The topology that is shown in the following figure provides the vPC
functionality to dual connected switches or servers with 10-Gigabit or 1-Gigabit Ethernet uplink interfaces.
Figure 15: Cisco Nexus 5000 Series Switch-to-Switch vPC Topology
The first 8 ports on the Cisco Nexus 5010 switch and the first 16 ports on the Cisco Nexus 5020 switch
Note
are switchable 1-Gigabit and 10-Gigabit ports. You can enable vPC functionality on these ports in 1-Gigabit
mode.
The switch connected to the pair of Cisco Nexus 5000 Series switches can be any standards-based Ethernet
switch. Common environments to use this configuration include Blade Chassis with dual switches connected
to the pair of Cisco Nexus 5000 Series switches through vPC or Unified Computing Systems connected to
the pair of Cisco Nexus 5000 Series switches.
Single Homed Fabric Extender vPC Topology
You can connect a server with dual interfaces that are configured in a vPC to a pair of Cisco Nexus 2000
Series Fabric Extenders that you then connect single homed to the Cisco Nexus 5000 Series switches. The
