Hi Ben, Thanks for the information. This is exactly what I was looking for.
My implementation involves around 3K dynamic MACs. Couple of questions, 1. MAC eviction on table full. I took a look at NORMAL action Mac learning code. It had implemented MAC eviction by giving fair share of entries for the each port in the table. Is there something similar available for LEARN action? I didn't find a way to configure it. I am concerned about the case where DOS attack is done by sending ton of MAC on one port leading to flushing of MACs in other ports. 2. Will there be any noticeable performance difference between using action NORMAL and LEARN. Assuming there wouldn't be too much MAC movement.
