Straight-through and active-active topologies are not mutually exclusive; they can be deployed concurrently as
depicted in Figure 36.

About Fabric Extender Active-Active Topologies
Starting from Cisco NX-OS 4.1(3), you can connect a fabric extender to two Cisco Nexus 5000 Series devices
configured for vPC.
The fabric extender active-active configuration is fundamentally different from all others:
●
The vPC in this configuration refers to the fabric links connecting the fabric extender to the Cisco Nexus
5000 Series Switch.
●
The fabric extender line card now has two control-plane devices that have equal rights to configure the
fabric extender switch ports.
●
Because the fabric extender is not an independent switching entity, LACP is not 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.
●
In such a configuration, each HIF port on the fabric extender is treated internally as if it were a vPC port.
