I observed mac flapping issue observed in s7706 model..connected with e9000 servers.
I configured eth-trunk between both the devices.

I tried to troubleshoot but later its was observed multiple ports can have same mac address, I faced challanges in troubleshooting.

So whats is the logic behind: same mac address on different ports and how it is beneficial in network

The layer 2 ports on the switch don't keep a MAC address, while layer 3 ports have the MAC address.

You said that you observed the MAC flapping. I think you better check the ETH-trunk configuration to make sure if all the interfaces which should be added into the ETH-trunk have been added into it successfully.

Hello.
I am not sure but I have a suggestion that when you configure eth-trunk interface which aggregate several interface to the one, you got one interface with one mac address. After that packets will choose the relevant link to pass regrading there's src and dst mac address.

MAC address flapping indicates a loop. The possible cause is that the Eth-Trunk fails to be established. Check whether the aggregation mode on the server is the same as that on the switch.

You need to check the eth-trunk configuration on bot dudes, because. Fiesta check the interfaces that belong tonthe trunk side on switch, and then, on e9000, check inside the switch planes, on the CX card, also the configures interfaces on the trunk. Your problem seens to be like if you miss some interface in one side of the eth-trunk
