Ports enabled with port isolation cannot communicate with each other, and thus ports on
the same VLAN can be isolated. Port isolation provides secure and flexible networking
schemes for customers.
The interface protection function records the MAC address of the host connected to an
interface of the S9300, that is, the network adapter ID of the host. Only the host with the
specified MAC address can communicate with this interface. Hosts with other MAC
addresses are prevented form communicating with the interface. The interface protection
function prevents certain devices from access the network, thus enhances network security.
Data
Interface number
(optional) Maximum percentage values of broadcast traffic, unknown multicast
traffic, and unknown unicast traffic
