Two Tier and Three Tier Topologies for 1 Gb ToR VLT Deployment for Layer 2 and Layer 3

with Resiliency (Routed VLT)

In a 1 Gb ToR VLT Deployment fabric design, the S4810 aggregation switches connect to access switches

at 10 Gb. The maximum number of VLT aggregation is two switches and the maximum number of VLT

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 11. 1 Gb ToR VLT Deployment

Important: All the VLT aggregation switches must be same mode type for aggregation; for example,

S4810. On the VLT access, you must 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 to select the appropriate two tier Layer 2 VLT or Layer 3 with

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