Error: "wred-map-bytes must not be configured with wred-map-time"
Cause
You tried to configure a mixture of WRED map styles; both a WRED map that uses byte-based units, and a WRED map that uses time-based units.
You will trigger this error if you combine commands like these:
set policy qos name <policy-name> shaper profile <profile-name> queue <queue-id>> wred-map-bytes ...
set policy qos name <policy-name> shaper profile <profile-name> queue <queue-id>> wred-map-time ...
