Use the following tables as guideline to select the appropriate 2– 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, see Deployment Topology.
