About Port Isolation
Port Isolation prevents local switching among ports on a Netvisor ONE switch or on a pair of Netvisor ONE switches configured as a cluster. With Port Isolation, Netvisor ONE disables direct communication with hosts part of same Layer 2 domain connected to isolated ports or to mutually learn the other MAC address. Communication between these hosts occurs through a Layer 3 device. Use this feature to secure bridged east-west traffic through a firewall.
When using this feature on ports within a cluster, you must configure the port-link state association rules between the uplink ports and the downlink isolated ports.
