Nexus 5K COPP default configuration - CIR/BC values

Hi,

when comparing two copp related outputs, I get different information.

The "show platform ..." output displays more classes (policies) as there are class-maps configuried and different CIR/BC rates!

For example, the lacp class ist configured with cir 1024 kbps and bc 4800000 bytes. The show platform displays a cir of 128000 (?)  4687 (?).

Can anyone explain the second output and the difference of the CIR and BC rates?

Thanks!
Best Regards
Hakan
