CSCec66602
Description: Output queue drops are seen at less than line rate on the NM-1T3/E3.
Workaround: The NM-1T3/E3 supports line rate throughput for traffic with packet sizes of 1500
bytes. For traffic with smaller packet sizes, degradation in throughput will be seen. Therefore, for
traffic with packet sizes smaller than 1500 bytes, reduce the traffic rate until output queue drops are
not seen any more.
