Connection lines are missing in Topology Map

[p.hruby]

I installed APIC-EM 1.4.0.1959. When I perform network discovery using CDP and seed device all devices are properly discovered but some links are missing. I've tried it several times but there were always some link missing. In one case there was dispayed link which doesn't exist.

I attach screenshot of APIC-EM topology. Missing links are red hand-drawn.

Do you have any idea what I'm doing wrong or how to fix it?

No, after i do a 'show cdp nei', and  i have not seen domain-name. so, what i should do next step. keep the current or set domain-name for ap?? kindly waitting for you advice.

please do not set the domain-name.  that will definitely cause an issue with AP.

ok , by the way , in my apic-em platefom.  in inventory,does below issue is correct or not? there may have some information missing?

[aradford]

That is expected for the AP.

The uptime/polling is done on the WLC, not the AP.

Mine looks the same.
