For all the Topology views under SDN Manager, specifically SDN_SlaPath, the nex message is seen when selecting a Link pipe: SPC-OCC-11681: Unable to render topology
Component : Spectrum OneClick
SDN_SlaPath topology is an overlay topology, in fact all the typologies under SDN Manager are overlay topologies.
Link information tab shows low level connectivity for each connection such as, in case of physical device models, port level connectivity.
Since overlay connections don't have further low level connectivity, Link information tab is not supported for such connections.
This is working as designed.
