What is zyHostPort?
zyHostPort identifies the physical port on which the switch learned the IP address recorded in a given zyxelHostTable entry, or shows 'CPU' if the address belongs to the switch itself. Admins use this to trace which port a particular end-host's IP address is connected through, useful for locating devices during troubleshooting. For example, a value of 'CPU' in this field means the associated IP address is the switch's own management IP rather than a connected host's.
