Has anyone had issues with a LACP trunk to a Cisco Nexus 5K not coming up? I have the F5 trunk set up properly(passive,Long, auto, source/destination mac address) and all settings havebeen confirmed and reconfirmed on the the Nexus switch. The cisco snexus switch shows the interface going up and then down. Same on the F5 with LACP Actor out of sync and Partner out of Sync errors.
Could you please post your configuration from Cisco side?
