Issue

4241238

Description: Fixed TX timeout issue related to the esw_scheduling QoS feature.

Keywords: esw_scheduling QoS

Discovered in Version: 28.44.1036

Fixed in Release: 28.45.1020

4352025

Description: Fixed an out-of-space issue related to writing Type-Length-Value (TLV) entries to reclaim space by removing outdated or irrelevant configuration entries.

Keywords: TLV

4318537

Description: Fixed an issue where the AI and HAI parameters of the ZTR_RTTCC algorithm, when configured by users, were automatically overwritten upon link speed changes. With this fix, if AI/HAI values were tuned for link speeds other than 100Gb/s, users should now divide those values by (link_speed / 100) to maintain consistent congestion control algorithm behavior.

Keywords: Congestion control, ZTR_RTTCC

Discovered in Version: 28.44.1036
