Access Management
Overview
In networking, the ports in a Switch which access different users belong to the
same VLAN and they cannot communicate with each other, for the purposes of
security, simplicity, and saving VLAN resources. Different ports have different IP
addresses and only the users with an IP address which is allowed to pass the port
can access the external network through the port. You can achieve this
configuration using the functions binding Switch port with IP address and port
layer-2 isolating.
