load the correct software image configuration file for each type of switch from the TFTP/FTP site

during BMP. For information about BMP, refer to DHCP Integration.

• The pool of IP addresses for the management port for each switch in the fabric.

• The IP addresses (must be an even number) for the uplink configuration from the ISP service. The

uplink port number range is based whether a 10 Gb or 40 Gb bandwidth is selected.

– For a 10 Gb bandwidth, AFM supports 2–32 uplinks.

– For a 40 Gb bandwidth, AFM supports 2–8 uplinks.

• The IP addresses or VLAN ID for the downlink configuration to connect to the server or ToR.

• The protocol configuration for uplinks and downlinks.

Selecting a Layer 2 and Layer 3 with Resiliency (Routed VLT) Fabric Design

For workload migration over virtualized environments, use a Layer 2 VLT fabric design. To extend equal

cost multipathing capabilities, use the Layer 3 with Resiliency (Routed VLT) fabric .

AFM supports the following Layer 2 VLT and Layer with 3 with Resiliency (Routed VLT) fabric designs:

• 1 and 2 Tier 10 Gb for Layer 2 LAN/SAN for iSCSI

• 1 and 2 Tier for 10 Gb Layer 2 LAN/SAN for Fibre Channel

• 1 Tier for 10 Gb and 40 Gb ToR for Layer 2 and Layer 3 Resiliency (Routed VLT)

• 2 Tier and 3 Tier Topologies for 1 Gb ToR VLT Deployment for Layer 2 and Layer 3 with Resiliency

(Routed VLT)

• 10 Gb or 40 Gb Top of Rack Deployment (mVLT)

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

• 10 Gb Blade Switch (MXL) for Layer 2 and Layer 3 with Resiliency (Routed VLT)

For information about tiers, refer to Deployment Topology and Deployment Topology Use Cases.
