Lanz Mirroring feature allows users to automatically mirror traffic queued as a result of congestion to either CPU or a different interface.

LANZ is the EOS Latency and congestion ANalyZer. On DCS-7280, DCS-7020, DCS-7500 and DCS-7800 series, it allows monitoring congestion and transmit latencies on both front panel and CPU ports.

4.29.1F adds Latency Analyzer (LANZ) support to the Arista SwitchApp on 7130 series. LANZ monitors SwitchApp internal buffer congestion. When the number of bytes in a buffer is over a high threshold, a congestion start event is created. When the number of bytes in a buffer is below a low threshold, a congestion end event occurs. LANZ on SwitchApp does not report any congestion update as the buffer sizes are too small for it to be meaningful. As SwitchApp comes in different profiles, each profile has a different hardware behavior due to the underlying architectural difference.

4.26.0F adds Latency ANalyZer (LANZ) support to the Arista 7170 series. LANZ monitors the egress queue usage through

LANZ adds support for monitoring congestion on backplane (or fabric) ports on DCS 7304, DCS 7308, DCS 7316, DCS
