Arista Unveils Modern Stacking for Campus Networks

Arista Networks, a leading provider of cloud and AI networking solutions, announced innovations enabling customers to build scalable and resilient campus networks. Arista is introducing the Switch Aggregation Group (SWAGTM) capability in Arista EOS®that uses industry-standard Ethernet to group and manage individual switches via a single IP address. In addition, Arista CloudVision® Leaf Spine Stack (LSS™) Management allows operators to collectively manage a logical stack of switches within a single networking closet or across the entire campus. Arista EOS, SWAG and CloudVision LSS free customers from proprietary stacking protocols and design limitations while delivering extensive flexibility for network topologies and operations.

Historically, stacking has been the only option for achieving the goal of aggregated management across a group of switches. However, existing stacking solutions rely on proprietary cables and protocols to offer a single IP and common CLI interface. These systems also limit customers to specific hardware, complicate upgrades, restrict network design to ring or chain topologies, and can only operate within a limited switching closet scope. Customers are thus saddled with inflexibility, operational complexities, and increased costs.
