Hello, everyone!
In this post, I would like to share with you extended ECC connection.
For osn8800 EFI card, create extended ECC between different NE (NOT main/slave sub-rack ) with "NM_ETH/NM_ETH1/NM_ETH2/ETH1/ETH2/ETH3" NM_ETH/NM_ETH1/NM_ETH2: Connects the network interface on the equipment through a network cable to that on an NM server so that the NM can manage the equipment. Connects the NM_ETH network interface on one NE through a network cable to that on another NE to achieve communication between NEs. main/slave sub-rack communication by ETH port: Connects a network cable from the ETH1/ETH2/ETH3 interface on one subtract to corresponding interfaces on the other subtracts to achieve the communication between the master subrack and slave subtracts.

That's all, I hope you like it.
Thank you!
