Click the Apply button to accept the changes made. The fields that can be configured in IP-MAC-Port Binding Port Settings are described below: Parameter Unit From Port - To Port Mode Description Select the Switch unit that will be used for this configuration here. This option is only available if stacking is enabled. Select the appropriate port range used for the configuration here. Select the mode of access control that will be used here. Options to choose from are Disabled, Strict, and Loose. When a port is enabled for IMPB strictmode access control, a host can only access the port after the host sends ARP or IP packets and the ARP packet or IP packet sent by the host passes the binding check. To pass the binding check, the source IP address, source MAC address, VLAN ID, and arrival port number must match any of the entries defined by either the IP source guard static binding entry or the DHCP snooping learned dynamic binding entry. When a port is enabled for IMPB loose-mode access control, a host will be denied to access the port after the host sends ARP or IP packets and the ARP packet or IP packet sent by the host does not pass the binding check. To pass the binding check, the source IP address, source MAC address, VLAN ID, and arrival port must match any of the entries defined by either the IP source guard static binding entry or the DHCP snooping learned dynamic binding entry.
