Figure 10. 10 Gb or 40 Gb ToR VLT Deployment (mVLT)

Important:

All the VLT aggregation switches must be same mode type for aggregation; for example, Z9000. On the VLT

access, you can configure the same model type or mixed the following model types: S4810 and S4820T.

2 and 3 Tier 10 Gb ToR (mVLT) Deployment Topologies for Layer 2 or Layer 3 with Resiliency

AVC = Aggregation VLTi Capacity

DL = Downlink

DL BW = Down Link Bandwidth

FL BWB A & A = Fabric Link Bandwidth between Aggregation & Access

UL BW = Uplink Bandwidth

Use the following tables as guideline to select the appropriate 2– Tier Layer 2 VLT or Layer 3 with Resiliency (Routed

VLT) fabric design.

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

information about tiers, see Deployment Topology.
