Nexus 5548 rate limit

Question

Hello,
I am trying to setup a rate limit on fex ports (modl is N2K-C2248TP-1GE ) of a 5548UP (non L3)  -  Software version is : version 6.0(2)N2(2)
I have tried the following setup without success  :
ip access-list ACL_CUST
  10 permit ip 10.100.100.1/32 10.100.100.2/32
  20 permit ip 10.100.100.2/32 10.100.100.1/32
class-map type qos match-all CMQOS_CUST
  match access-group name ACL_CUST
policy-map type qos PMQOS_CUST
class CMQOS_CUST
    police cir percent 1 bc 200 ms conform transmit violate drop
interface Ethernet161/1/11 - 12
  service-policy type qos input PMQOS_CUST
And also tried to use this confioguration :
class-map type qos match-all CMQOS_LIMIT_BP_CUST
  match cos 0-7
policy-map type qos PMQOS_LIMIT_BP_CUST
  class CMQOS_LIMIT_BP_CUST
    police cir percent 1 bc 200 ms conform transmit violate drop
interface Ethernet161/1/11 - 12
  service-policy type qos input PMQOS_LIMIT_BP_CUST
The problem is that the bandwith restriction (1 percent of 1Gbit/s shoud be 10Mbit/s) is not working and apparently no restriction is applied
If someone could help me to resolve this issue it would be greatly appreciated
I do have followed this guide
