Symptom

When using Nexus 9000 Cloud-Scale ToR or EoR line cards for Tap aggregation, there is a potential for the same MAC address to become visible across different ingress ports as customers tap different points in their network. In Nexus 3Ks, Nexus 9300 and Nexus 9500 with T2 line cards, we have the ability to disable the MAC learning globally. This command has not been made supported for the Cloud-Scale platforms: switch# sh mod | i i EX 1 54 48x10/25G + 6x40/100G Ethernet Module N9K-C93180YC-EX active * switch(config)# mac-learn disable config not supported on platform

Conditions

9300-EX/-FX/-FX2/-GX platform switches and Cisco Nexus 9500 series platform switches with -EX/-FX line cards
