Port Security

Moxa switches provide a Port Security function that lets packets with allowed MAC Addresses access the

switch’s ports. Two Port Security modes are supported: Static Port Lock and MAC Address Sticky.

Static Port Lock: Allows users to configure specific MAC addresses that are allowed to access the port.

MAC Address Sticky: Allows users to configure the maximum number of MAC addresses (the Limit) that a

port can “learn.” Users can configure what action should be taken (under Violation Port Disable) when a new

MAC address tries to access a port after the maximum number of MAC addresses have already been learned.

The total number of allowed MAC addresses cannot exceed 1024.
