20.1 Port Security Overview

This chapter shows you how to set up port security.
Port security allows only packets with dynamically learned MAC addresses and/or configured static
MAC addresses to pass through a port on the OLT. The OLT can learn up to 16K MAC addresses in total
with no limit on individual ports other than the sum cannot exceed 16K.
For maximum port security, enable this feature, disable MAC address learning and configure static MAC
address(es) for a port. It is not recommended you disable port security together with MAC address
learning as this will result in many broadcasts. By default, MAC address learning is still enabled even
though the port security is not activated.
