We have numerous implementations of Arista switches. Cisco has a significant issue. It cannot maintain its service commitment regarding daily LAN returns, leading to client dissatisfaction. There are substantial delivery delays. Furthermore, Cisco currently charges double for the same product, which impacts cost-effectiveness. We found an issue with Arista Campus LAN Switches regarding license renewals. We have to renew the license every three years, which can be a challenge for customers. Arista, like other vendors, now follows a license-based system. In the past, we could purchase a Cisco system that would run without needing continuous license renewals. However, the current model requires regular license renewals, typically every three years, similar to Arista's approach. The renewal cost for Arista licenses is quite high. For instance, Cisco's renewal cost is about 22% of the total system cost, and Aroware also has a 22% renewal cost. In contrast, Arista's renewal cost is almost 55% or more, presenting a significant challenge for customers.
