Any errors in any of these registers may indicate a hardware error in the HSB SRAM that impedes traffic through embedded Packet Velocity Acceleration (ePVA). ... In that case, ePVA-accelerated flow might fail. ... With a burst of CRC errors in the SRAM for ePVA transformation cache, it does not trigger a failover and causes a silent traffic outage on the FastL4 VIP with hardware traffic acceleration. ... This occurs because the health check watchdog packets are still functioning correctly, and the current TMOS software primarily monitors watchdog packets tx/rx failures to trigger failover. ... In these cases, there might be the following messages in /var/log/tmm*: Device error: hsb_lbb* tre2_crc_errs count * ... Traffic is offloaded to HSB hardware for acceleration. ... Switch traffic to software acceleration. ... Fix Information ... Including traffic-critical registers in failover triggers, helps failover happen quickly with minimum disruption to traffic in the case of SRAM hardwar...
