unformat failed to parse parameters of u32 followed by u16. u32 always get 0. here is the sample code and test result.

static clib_error_t *
f(vlib_main_t *vm, unformat_input_t *input, vlib_cli_command_t *cmd)
{
u32 x=1;
u16 y=2;

unformat(input, "%d %d", &x, &y);

printf("\nx=%d y=%d\n", x, y);

return 0;
}
