There are many dump_xxx cmd, suggest the commands as dump_lcores:
testpmd> dump_
 dump_physmem [Mul-choice STRING]: Dump status
 dump_memzone [Mul-choice STRING]: Dump status
 dump_socket_mem [Mul-choice STRING]: Dump status
 dump_struct_sizes [Mul-choice STRING]: Dump status
 dump_ring [Mul-choice STRING]: Dump status
 dump_mempool [Mul-choice STRING]: Dump status
 dump_devargs [Mul-choice STRING]: Dump status
 dump_log_types [Mul-choice STRING]: Dump status
 dump_ring [Mul-choice STRING]: dump_ring|dump_mempool <name>: Dump one ring/mempool
 dump_mempool [Mul-choice STRING]: dump_ring|dump_mempool <name>: Dump one ring/mempool
