Aruba ESP Campus LAN Design

The Aruba CX switching portfolio provides a range of products for use in core, aggregation, and access layers of the campus. Aruba switches are built using a cloud-native operating system called AOS-CX. To achieve increased network resiliency and facilitate automation, AOS-CX implements a database-centric operational model.

With features such as always-on PoE, Virtual Switching Framework (VSF) for access stacking, and Virtual Switching Extension (VSX) for core and aggregation redundancy, organizations can rely on Aruba CX switches to satisfy mission-critical requirements throughout the campus.

Aruba ESP campus LAN design focuses on the two most common topologies:

  • Two-tier with collapsed core.
  • Three-tier using aggregation.

Redundant, routed links are the preferred uplink configuration between switches. Though most networks deployed today are configured for layer 2 access and routing at the core or aggregation layer, organizations looking ahead to software-defined overlay topologies should start moving toward layer 3 access with routing at the edge to increase underlay network resilience.

The Aruba ESP campus LAN design may contain one or more of the following elements:

  • Aruba Central
  • Aruba ClearPass
  • Aruba CX 8xxx Ethernet switches
  • Aruba CX 6xxx Ethernet switches.
