Deployment Options Description

Oversubscription Ratio (Layer 3

distributed core deployment

topology only)

For a Layer 3 deployment, the following oversubscription ratios are

available:

• 1:1

• 3:1

• 4:1

• 5:1

Resiliency in Access Devices Configures Virtual Router Redundancy Protocol (VRRP) on the

downlink.

10 GB Cable Type for Access Tier This option is applicable only for topologies where S4810 and

S4820T can be swapped.

• SFP+

• RJ-45

Stacked/Non-Stacked Selects stacking for the applicable topologies. If you select

stacking, you can enable VLTi.

High Stream Buffering

• high stream buffering — For an access layer using S60

switches

• low latency — For an access layer using S55 switches

Resiliency In MXL (Routed VLT)

• Intra-chassis — Within the chassis (mVLT)

• Inter-chassis resiliency — Across 2 chassis (VLT)

• One-Tier Topology — Contains two switches and a downlink and uplink configuration. There are no

fabric links.

For more information about one-tier topologies, refer to Designing a Layer 2 VLT and Layer 3 with

Resiliency (Routed VLT) Fabric.

• Two-Tier Topology — Contains two layers of switches. Has fabric interlinks, uplinks, and downlinks.

Uses Distributed Core (spine and leaf) or VLT (aggregation and access). For more information about

two-tier topologies, refer to Designing a Layer 2 VLT and Layer 3 with Resiliency (Routed VLT) Fabric

and Selecting a Layer 3 Distributed Core Fabric Design.
