When I compare the Cisco CLI with the Spectrum LACP Spotlight View. Spectrum is not showing all nexus port channels and shows not all channel member ports or shows incorrect member ports.
Release : 21.2.x, 22.2.x
The missing information for Cisco Nexus is located in the CISCO-LAG-MIB and this data was not used in Spectrum
This has been resolved in 21.2.8 with patch PTF_21.2.816.
This should be available out of the box in Spectrum 22.2.5 and higher.
