Configuring Port Security
Port security changes the dynamic MAC addresses learned on an interface into secure MAC addresses. This function prevents unauthorized users from communicating with the switch using this interface and
therefore enhances switch security.
Pre-configuration Tasks
Before configuring port security, complete the following tasks:
- Disable MAC address limiting on the interface.
- Disable MUX VLAN.
- Disable MAC address security for DHCP snooping on the interface.
