Modern Massively Scalable Datacenters (MSDCs) delivering high availability software such as Software-as-a-Service (SaaS), Infrastructure-as-a-Service, etc. have stringent metrics to which to adhere. Link availability is one such crucial factor. Techniques presented herein may facilitate decreasing link bring-up time by maintaining a cache for link training (LT) transmit (TX) Finite Impulse Response (FIR) settings. Thus, these techniques may provide for faster link bring-up, faster convergence, and faster fabric module bring-up in an End of Rack (EoR) chassis. Using techniques presented herein, faster link bring-up may become the norm rather than the exception.
