Use Trusted Host function to manage the switch from a remote station. You can enter up to ten designated
management stations networks by defining the IPv4 Address/Netmask as seen in the figure below. The first
thing after the function is enabled is to add your local host IP address as a trusted host. Otherwise, you may
lose the connection.

Port Security is a security feature that prevents unauthorized computers (with source MAC addresses)
unknown to the Switch prior to stopping auto-learning processing from gaining access to the network.
Security > Port Security
A given ports’ (or a range of ports') dynamic MAC address learning can be stopped such that the current
source MAC addresses entered into the MAC address forwarding table cannot be changed once the port
lock is enabled.
