Currently Network Topology Mapper (NTM) OID used to discover machine type are very limited.
As a result newer Cisco switches like 9k serie which will replace most of 3750,2960,4500,6500,6800 ... are not discovered.
And as such NTM will be become useless to generate accurate inventory of assets.
We should have others OID like for NCM tool to be able to discover correctly all model of Cisco 9k switches.
