How does the user password aging work on ICX devices after the 180 days o more?

Hi everyone!I would like to know how the user password aging works. I read the security config guide for the  firmware version 08070 (that is the code that I have in the switches). It says when the user aging is enable, the CLI will automatically prompt users to change their passwords when they attempt to sign on. So, if after 180 days I try to log in to the switch, do I have to put my old password and then the CLI ask for a new one? Can I change the period of time of 180 days?Also, is there a way to sync this password update if I have multiple switches with user password aging enabled? I mean, Can I only change or update in one switch and this change will be sync in the others?I hope someone can help me.Regards.
