Yes – and from a lab exam perspective – it is just a matter of having the sticky command in there typically in order to receive full marks.

Now, is there a way for a MAC learned via sticky to "survive" reboot and remain in the config? I know that once it is learned , one may do a write mem and that will save it, however is there a way that it can be saved without intervention? [...] There's a solution, but it is still based on "write memory", so I would call it rather a workaround. It uses "kron" command to do "write memory" every 10 minutes: kron occurrence WRITE-MEM in 10 recurring policy-list WRITE-MEM ! kron policy-list WRITE-MEM cli "write memory" So in this case, if the switch learns MAC address via "sticky" in port-security, the address will be saved in running-config immediately and in startup-config after 10 minutes. -- Marta Sokołowska.
