Hi all! How can I automate the process of cleaning the mac address table. Due to the frequent use of Apple technique and the constant change of mac address, I have overflow. Where can I find the configuration in nebula?

    Hi @WhoYouNow

    Thank you for sharing your switch models.

    Currently, Nebula Cloud does not provide a mechanism for Nebula switches to automatically flush the MAC table. Generally, automatically flushing the MAC table is not reasonable as it may lead to short-term traffic forwarding issues.

    By the way, the switch defaults to flushing the port MAC when the port client does not respond for at least 5 minutes, and when the port is unplugged. However, it does not flush the table by interval automatically.

    Additionally, you can flush the MAC table via the SSH command: mac-flush [<port-num>]. For switches running firmware version V4.80 or above, you can access it remotely via the 💎 Remote SSH function on Nebula CC. For firmware versions V4.70 or below, please access SSH locally.

    Hi @WhoYouNow

    For the switches, there is no difference between the physical real MAC address and the virtual MAC address.

    When a MAC address dynamically changes, the mechanism we mentioned will age out the MAC address from the MAC table if there is no response for 5 minutes.
