An engineer is deploying a new UCS chassis with two Fabric Interconnects. The design requires that server traffic can fail over to the secondary FI if the primary FI fails, without requiring any changes to the server's network configuration. Which technology must be enabled on the uplink ports of the Fabric Interconnects to the upstream switches to ensure transparent failover of server traffic?
Trap 1: Configure a virtual PortChannel (vPC) between the Fabric…
vPC provides active-active uplinks but does not handle MAC/IP takeover for FI failover.
Trap 2: Apply QoS policies to prioritize failover traffic.
QoS does not provide transparent failover.
Trap 3: Implement Private VLANs on the uplink ports to isolate traffic.
PVLANs are for traffic segmentation, not FI failover.
- A
Configure a virtual PortChannel (vPC) between the Fabric Interconnects and upstream switches.
Why wrong: vPC provides active-active uplinks but does not handle MAC/IP takeover for FI failover.
- B
Apply QoS policies to prioritize failover traffic.
Why wrong: QoS does not provide transparent failover.
- C
Enable pin groups with 'failover' mode on the server ports.
Pin groups with failover mode allow the secondary FI to assume the primary's MAC and IP, enabling transparent failover.
- D
Implement Private VLANs on the uplink ports to isolate traffic.
Why wrong: PVLANs are for traffic segmentation, not FI failover.
