Guide or reference, bosses, I appreciate, or don't have this module can also be to implement in other ways, my environment is as follows:
Core cisco4506, gathering cisco3750 access cisco2960, due to historical reasons are not configured SSH, too many not equal to come over, I hope after unified management can scale configuration
