FL BW AA = Fabric Link Bandwidth between Aggregation & Access

UL BW = Uplink Bandwidth

Use the following tables as guideline to select the appropriate two tier Layer 2 VLT or Layer 3 with

Resiliency (Routed VLT) fabric design for a 40 Gb ToR (mVLT deployment).

NOTE: With a Layer 2 VLT fabric, the uplinks come from the switches on the aggregation side. For

information about tiers, refer to Standard Fabric Design — Deployment Topology.
