max-rate 413202
Before enabling dist-lag-rate-shared, in the port-scheduler-policy psp, the max-rate
achieved is twice 413202 kbps 816Mbps. This is because LAG has members from two
different cards.
Two port-scheduler-instances are created, one on each card with the max-rate of 413202
kbps. This can be confirmed using the following show o/p.
Once dist-lag-rate-shared is enabled in port-scheduler-policy, this max-rate is enforced across
all members of the LAG.
