type (topology). Based on the selected deployment type options, different downlinks options are

configured at the access tier.

The following section lists the available topology types:

1. Layer 3 with Resiliency (Routed VLT) with stacking option – If you select the Stacking option,

configure the VLAN with the primary and secondary IP addresses for each access switch.

2. Layer 3 with Resiliency (Routed VLT) with VLT option – If you select the VLT option, enter the

VLAN ID, Primary IP address and Secondary address. If you select the Enable Layer 3 Protocol in

Access Switches option, configure the VLAN ID and the IP Range. When you complete the pre-

deployment configuration, the Advanced VLAN IP Configuration option is available at the Configure

and Deploy summary screen.

Configuration

3. Layer 3 with Resiliency (Routed VLT) – Basic option – If you select the Basic option, configure the

VLAN with the primary and secondary IP addresses for each access switch.

4. Layer 3 with Resiliency (Routed VLT) – Blade MXL with IntraChassis option: For this topology,

select the deployment type with an MXL Blade switch with Resiliency (VLT) and the Intrachassis

(within the same chassis) resiliency option. Enter the VLAN ID, primary, and secondary IP addresses.

Using the Fabric Design Wizard

To design the following types of customized fabrics based on your workload requirements for your

current and future needs, use the Fabric Design Wizard on the

Network > Design Fabric > New Fabric

screen. If you are designing a Layer 2 fabric using an IOA blade, refer to Using the IOA Pre-deployment

Wizard.

• Layer 2 — Use the Layer 2 VLT fabric for workload migration over virtualized environments. Refer to

VLT and Selecting a Layer 2 and Layer 3 with Resiliency (Routed VLT) fabric.

• Layer 3 distributed core — Use the Layer 3 distributed core for large fabric deployments. Refer to

Conventional Core Versus Distributed Core

• Layer 3 with Resiliency (Routed VLT) — Use the Layer 3 fabric to extend equal cost multipathing

capabilities. Refer to Selecting a Layer 2 and Layer 3 with Resiliency (Routed VLT).

This screen allows you to create, edit, delete, and view the fabric.

NOTE: You can also use the Fabric Design Wizard from the Home > Design New Fabric screen.
