Question Image

A Cisco engineer is configuring an active/active design consisting of Cisco Nexus 7000 Series Switches with Fabric Extenders using a vPC. The goal is to connect servers, storage, and devices to a single FEX, using the FEX port channels to each parent switch for redundancy. The engineer configures the FEX and FEX ID identically on both sides. During initial testing, a problem occurs with the straight-through FEX and active/active FEX configuration. What is the most likely reason?

  • A They are not enabled on vPC+ deployments.
  • B FEX-AA is not a supported F-Series module.
  • C They cannot exist on the same ASIC instance.
  • D Full duplex is disabled for FEX connectivity.
Explanation

For Cisco Nexus 7000 FEX active-active deployments, the two parent switches must use the same FEX ID and matching configuration. However, Cisco does not permit straight-through FEX and active-active FEX to coexist on the same ASIC instance.
