+ These drops are of the type: UC TENANT MYTEP BRIDGE MISS, ACL DROP, MC FIB MISS. i.e.
module-1# show plat internal hal 12 port gpd | egrep "Ss|1/63" (output shows S1=0, Ss=14)
module-1# show platform internal asic (output shows SliceSrc [0x14] : UC TENANT MYTEP BRIDGE MISS, ACL DROP, MC FIB MISS,)
+ These drops show up as Interface QoS Receive Error on NDI
+ Customer will like this Interface QoS Receive error due to sup redirected packets not be sent to NDI
