As shopper customers, units, and IoT proceed to proliferate, the necessity for switching administration and workload optimization throughout domains will increase. Many sub-optimal and closed approaches have been designed up to now. Arista was based to construct the most effective software program and {hardware}, equating to the very best efficiency and density in cloud/knowledge facilities, and now evolving to campus switches. In 2020, we launched the smallest footprint of Arista CCS 750 and 720 collection switches as a becoming instance of the very best density and lowest footprint.
But clearly, there are occasions when these switches should be managed as one entity for purchasers to construct and function versatile designs and topology. Within the Nineties, this was executed with proprietary cabling {hardware} and closed stackable ring or chain topologies. It is a closed and cumbersome strategy because the administration scope is restricted to small numbers (lower than 10) of switches and depends on proprietary mechanisms.
Bringing SWAG to Switching
Arista clients acknowledged the constraints of this legacy stacking strategy and inspired us to assist them break away from these shackles. So, we’re embarking on one more breakthrough innovation for contemporary enterprises. The pioneering efforts started within the early 2010s with MLAG, whereby one might mixture a number of active-active hyperlinks and allow alternate and redundant paths to switches within the knowledge middle.
Constructing upon that MLAG expertise, Arista SWAG™ (Swap Aggregation Group) brings fashionable stacking to campus switches. Arista SWAG permits a set of switches to be grouped and share a centralized management aircraft, thus offering the power to function the group of switches via a single IP handle and a single CLI interface for automation. SWAG relies on Arista EOSⓇ and helps a number of topologies, together with Arista’s common Leaf-Backbone design and the extra conventional ring or chain. Importantly, it could scale as much as 48 campus stacking components.
Imagine offering all the advantages of legacy stacking with out the constraints! A few of these advantages embody:
- Can scale to as much as 48 switches in a single group, permitting for elevated IP handle conservation
- Can lengthen the scope of the cluster past simply ‘IDF closet’ to a bigger area within the community
- Helps the extremely resilient and the excessive capability Arista validated Leaf-Backbone topology along with Ring and Chain topologies
- Minimal downtime resulting from key capabilities reminiscent of good software program upgrades (SSU) which might be inherited since SWAG is constructed on the identical confirmed EOS software program
Our clients now have the pliability to carry out community operations on a logical stack of switches in a standards-based, open, fashionable leaf backbone structure, as proven within the determine under.
Arista’s SWAG for Trendy Campus Stack

The Highway Forward – Keep away from the Stackable Tax
Arista CloudVision LSS™(Leaf Backbone Stack) administration brings swagger to switches! CV LSS reduces complexity in configuration and upkeep by permitting a number of switches to function underneath single-entity administration. By linking switches collectively right into a “digital stack,” directors get the most effective of each worlds. Clients can logically arrange teams of switches based mostly on real-world constructs, reminiscent of buildings or flooring inside CloudVision LSS Administration, after which carry out community operations reminiscent of onboarding, provisioning, monitoring, upgrading, and configuring seamlessly throughout the whole group. Enterprises additionally profit from versatile community designs, whether or not the grouped switches are in standalone mode, a chassis, MLAG, or SWAG-based stack mode.
Arista’s fashionable software program is inherently designed with key availability and segmentation methods that separate administration and management planes, thus avoiding the pitfalls of proprietary stacking. This simplified stacking strategy improves operations, minimizes downtime, and reduces TCO—an development that has been a very long time coming.
The networking business has been working in cumbersome silos and closed proprietary networks for too lengthy. It’s the proper time to rework into a brand new, fashionable working mannequin. Welcome to the brand new world of SWAG!
We want our readers a contented vacation season and new 12 months forward!
