Port Security Configuration Guidelines
Follow these guidelines when configuring port security:
•Port security can only be configured on static access ports or trunk ports. A secure port cannot be a
dynamic access port.
•A secure port cannot be a destination port for Switched Por t Ana ly zer (SPAN).
•A secure port cannot belong to a Gigabit EtherChannel p ort gro up.
Note Voice VLAN is only supported on access ports and not on trunk ports, even though the
configuration is allowed.
