access switches is based on the number of uplinks and downlinks in the fabric. With this topology, the

downlinks connect to access S55 or S60 switches using a 1 Gb bandwidth.

Figure 8. 1 Gb ToR VLT Deployment

NOTE: All the VLT aggregation switches must be same mode type for aggregation (for example,

S4810). On the VLT access, configure the same model type.

AVG = Aggregation VLTi Capacity

DL = Downlink

DL BW = Down Link Bandwidth

FL BW AA = Fabric Link Bandwidth between Aggregation & Access

UL BW = Uplink Bandwidth

BW = Bandwidth

Use the following table as guideline for selecting the appropriate two-tier Layer 2 VLT or Layer 3 with

Resiliency (Routed VLT) fabric design for a 1 Gb ToR VLT deployment.

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

side. For information about tiers, refer to Deployment Topology.
