We have Spectrum integrated with OneClick and we utilize the favorites option in OneClick to help same time when drilling down through multiple topologies.
We have noticed that if we take an SDN Container and right click and add to favorites that the container does not expand nor does this show the rollup alarms.
When we do this with a container that was discovered by Spectrum, then it works as expected.
Spectrum 23.x
VNA 23.x
SDN hierarchy is built on SDN_Contains relations between SDN elements and OneClick favorites aren't aware of this hierarchy.
Feature Request F51809 has been opened to have this added in a future Spectrum release.
