warning error " Unsupported bandwidth remaining ratio configured

JoyW
Level 1
Level 1

 

We are experiencing a warning error "Unsupported bandwidth remaining ratio configured" while setting up the QoS policy map `QoS-Output-queuing` on a Cisco 8000 series router running IOS XR version 7.8. This issue indicates that the bandwidth remaining ratios set for different traffic classes exceed the system's supported range. Specifically, the ratios are configured as follows in the policy map: `class tc4` at 30%, `class tc6` at 5%, and `class class-default` at 65%, totaling 100%. We suspect this may be due to a compatibility issue with the firmware version. Are there any firmware updates or other configuration recommendations that can resolve this issue?
