160-Gbps vPC Between the Cisco Nexus 5000 and Cisco Nexus 7000 Series
The Cisco Nexus 5000 Series hardware supports 16-port PortChannels. The Cisco Nexus 7000 Series supports 16-
port virtual PortChannels with 8 ports per Cisco Nexus 7000 Series. This allows the implementation of the topology
shown in Figure 16.

vPC Considerations for a Cisco Nexus 2000 Series Fabric Extender Dual-Attached to a Cisco Nexus 5000
Series Switch
Starting from Cisco NX-OS Software Release 4.1(3), it is possible to connect a fabric extender to two Cisco Nexus
5000 Series devices configured for virtual PortChannels. The fabric extender is a satellite switch that depends on the
Cisco Nexus 5000 Series for both configurations and forwarding. As a result, this vPC configuration is fundamentally
different from all others, starting with the fact that the fabric extender line card must now control plane devices that
have equal rights to configure the fabric extender switch ports.

The other significant difference is that, because the fabric extender is not an independent switching entity, no LACP
protocol is configured on the links connecting the fabric extender to the Cisco Nexus 5000 Series Switches. The
bundling of fabric extender ports is handled with internal protocols.

Finally, in this kind of configuration, each individual port on the fabric extender is treated internally as if it was a vPC
port.

Figure 17 illustrates the configuration elements of such a topology. The Cisco Nexus 5000 Series devices are
configured like regular vPC topologies with a peer link, a peer-keepalive link, and so on.
