Which of the following Arista switches support LANZ?

Latency Analyzer (LANZ) is an advanced Arista EOS feature designed to detect and report microbursts and network congestion events in real-time. This functionality requires specific hardware support found in Arista's high-performance data center switching platforms. The Arista 7150 Series (ultra-low latency), 7500E Series (modular chassis), and 7050 Series (which includes the 7048T-A model) are all documented to support LANZ. These platforms possess the necessary architecture to monitor buffer utilization at a granular level and trigger alerts when congestion thresholds are exceeded, which is the core of the LANZ feature.

A. 7010: The 7010 Series is a line of high-density, low-power 1GbE switches that lack the advanced hardware architecture required for sophisticated monitoring features like LANZ.
