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.

MetaMux is an FPGA-based feature available on Arista’s 7130 platforms. It performs ultra-low latency Ethernet packet multiplexing with or without packet contention queuing. The port to port latency is a function of the selected MetaMux profile, front panel ingress port, front panel egress port, FPGA connector ingress port, and platform being used.

MetaWatch is an FPGA-based feature available for Arista 7130 Series platforms. It provides precise timestamping of packets, aggregation and deep buffering for Ethernet links. Timestamp information and other metadata such as device and port identifiers are appended to the end of the packet as a trailer.

MultiAccess is an FPGA-based feature available on certain Arista 7130 platforms. It performs low-latency Ethernet multiplexing with optional packet contention queuing, storm control, VLAN tunneling, and packet access control. The interface to interface latency is a function of the selected MultiAccess profile, front panel interfaces, MultiAccess interfaces, configuration settings, and platform being used.

SwitchApp is an FPGA-based feature available on Arista’s 7130LB-Series and 7132LB-Series platforms. It performs ultra low latency Ethernet packet switching. Its packet switching feature set, port count, and port to port latency are a function of the selected SwitchApp profile. Detailed latency measurements are available in the userguide on the Arista Support site.

Arista’s DCS-7130LBR series of switches are capable of supporting SwitchApp, which is an FPGA-based L2/L3 switch. However, as the switch would then contain two switch ASICs (one traditional switch ASIC, and one FPGA-based switch) physically upon loading the SwitchApp application, there are certain limitations and nuances along with its usage. This document intends to explain some of the details.
