Important: In a single distributed fabric, all the leaves can act as a non-ToR or as a ToR, not both at the same
time.
Key Considerations for Designing a Distributed Core
When designing the Layer 3 distributed core fabric, consider the following:
• You can deploy up to 10 fabrics. However, the fabrics do not communicate with each other.
• AFM manages Dell S4810, S4820T, S6000, and Z9000 switches.
CAUTION: If you are already using a deployed switch, reset the factory settings. The switch must be in BMP mode.
For information on BMP, see DHCP Integration and the
FTOS Configuration Guide
for either the S4810, S4820T, S6000, or
Z9000 switches at https://www.force10networks.com/CSPortal20/KnowledgeBase/Documentation.aspx. See also
Deployment Topology Use Cases.
The number and type of spines and leaves (switches) in a distributed core fabric are based on the following:
• The type of distributed core fabric design:
– Type 1: Extra Large Core
– Type 2: Large Core
– Type 3: Medium Core
– Type 4: Small Core
• The number of current uplinks and downlinks for the leaves.
• The number of planned edge ports (future uplinks and downlinks) for the leaves.
• Whether you require non-blocking (line rate) performance.
