I see Topology Manager is being phased out. In fact it is already disabled from Netsight 6.3.
However it is a very cool tool and the Map feature in OneView doesn't do it entirely justice.
Now my pros and cons of OneView Maps (OVMs)
* Port numbers are shown directly on the link without having to click --> WIN
* No STP/MSTP overlay in OVM --> FAIL
* VLAN overlay does not color the links or the individual egresses of the VLANs on trunks --> FAIL
* List of links and link details screen in OVM --> WIN
If you now translate the FAILs to Feature Requests, then I guess we have it...
Thanks and keep up the good work
