Protocol Configuration - Layer 3 Distributed Core Fabric: Step - Dell Active Fabric Manager Deployment Manual

• Downlink Port Configuration — (for a Layer 2 VLT fabric only) Associates each of the ports of a leaf (on a per
leaf basis) to one or more VLANs. You can associated one or more tagged VLANs one and for untagged VLAN
only one is allowed.
• VLT VLAN Configuration — (for a Layer 2 VLT fabric only) Specify a VLT VLAN to be applied to the Layer 2 fabric.
Include at least one VLAN configuration.
• Downlink Configuration — An edge port that connects to the access layer; for example, servers or a ToR.
• Assign Switch Identities— Assigns a system MAC address to each switch in the fabric. You can optionally
assign serial numbers and service tags to each switch.
• Management IP — Specifies a management IP address to each switch.
• Software Images — Specifies the TFTP or FTP address (local or remote server) and the path of the FTOS
software image download to each type of switch. To stage the software, use this address.
• DHCP Integration — Creates a dhcp.cfg file that loads the correct software image and then a configuration file
for each type of switch. The DHCP server also uses this file to assign a management IP address to each switch.
NOTE: Install the DHCP configuration file on the DHCP server before you deploy the fabric.
• Output — Displays the uplink and downlink configuration on the leaves. Verify that this information is correct
before deploying the switches.
• Summary — Displays the fabric name, location of the software image, and DHCP configuration file.
Protocol Configuration — Layer 3 Distributed Core Fabric: Step 1 — 3
To configure the pre-deployment protocol configuration for a Layer 3 distributed core fabric, complete the following
tasks:
1. Pre-deployment – Step 1: Fabric Interlink Configuration
2. Pre-deployment – Step 2: Uplink Configuration
3. Pre-deployment – Step 3 Downlink Configuration
NOTE: For pre-deployment, the Layer 2 VLT and Layer 3 Distributed Core fabrics use the same pre-deployment
configuration screens from step 4 through step 10. See also
Pre-deployment – Step 1: Distributed Core Fabric Interlink Configuration
To configure the links that connect the leaves and spines for a Layer 3 distributed core fabric using the OSPF routing
protocol, use the Fabric Interlink Configuration screen. The port bandwidth (a read-only field) is automatically
determined by the selected fabric type and fabric oversubscription ratio (Layer 3 distributed core fabric only). To
automate the pre-deployment process, AFM automatically populates the starting IP address range/prefix, loop IP
address/prefix based on the fabric design, and sets the area ID for OSPF to "0". Review these settings. You can modify
the IP address range and loopback address. The start prefix for both types of addresses must be from 8 to 29 and the
loopback prefix from 8 to 26. Before you begin, review the
Wizard: Introduction sections.

Fabric Interlink Configuration
CAUTION: The area ID for the interconnect link must not be the same as the area ID specified for the uplink.
