Hi Rengar,
Manually configured sticky MAC entries and automatically generated sticky MAC entries are automatically saved every 10 minutes or saved in a file with the suffix ztbl or ctbl using the save command. The saved file is not discarded after the device restarts. The file name must be the same as the system configuration file name. For example, if the system configuration file is test.cfg, the sticky MAC entry file must be test.ctbl. Otherwise, the sticky MAC entry fails to be restored after the device restarts.
I hope it helps!
