GigabitEthernet0/3 buffers, 512 bytes (total 1000, permanent 1000): 0 in free list (0 min, 1000 max allowed) 1000 hits, 325295516 fallbacks <== 1000 max cache size, 0 in cache 167843697 hits in cache, 325295516 misses in cache 14 buffer threshold, 21502 threshold transitions Conditions: This will happen when the incoming interface is faster than the outgoing interface [for e.g. incoming GIGE and Tx as CT3 in this case] and the TX interface has a holdq config in it with multiple sub interfaces.
