Transceiver Performance Monitoring and Enhanced Diagnostics

Description This feature adds support for viewing the Digital Optical Monitoring (DOM) parameters for the optics that support enhanced diagnostics from the CLI. The show commands described later in this document can be used to view the instantaneous values for various modulation parameters like Signal-To-Noise Ratio, Residual Inter Symbol Interference, PAM4 Level Transition Parameters, etc. that such optics support. EOS-4.18.0F also introduces the Performance Monitoring feature wherein EOS collects and maintains certain performance statistics over a user-defined time period. EOS stores data for two intervals, the current interval and the most recently completed interval. When the current interval completes, the...

Coherent PHYs and Optics

Updates Specific to EOS 4.21.0F and Subsequent Releases Note: EOS 4.21.0F and subsequent releases may require manual updates to frequency or channel and grid spacing in the configuration sections for interfaces that utilize tunable (non-SFP+) form factor transceivers. EOS 4.21.0F and subsequent releases errdisable interfaces utilizing a tunable (non-SFP+) form factor transceiver by default. Removing the errdisabled condition from an interface requires specifying an explicit, valid tuning frequency configuration for the interface. The following TOI is an extension of the Coherent PHYs and Optics TOI here: https://eos.arista.com/eos-4-17-0f/coherent-phys-and-optics/ Configuration Enhancements for configuring frequency/wavelength Note: These enhancements do not affect 10GBASE-DWDM SFP+...
