Symptom
The issue is specific to N9K-C93180YC-EX switches only;
When PBR sets several next-hops with "load-share" keyword, and in case the traffic has to be sent out (load-shared) over several port-channel interfaces further, an issue might be observed with load-balancing of the traffic over the physical member interfaces on these port-channel interfaces.
Conditions
The issue is specific to N9K-C93180YC-EX devices only.
The issue is not seen on -FX series devices (like N9K-C93180YC-FX).
PBR has to set several next-hops for the matched traffic with "load-share" keyword enabled.
The matched traffic has to be sent out further ("load-shared") over port-channel interfaces.
