Select the enable or disable the IP-MAC-Port binding option's trap state.
Description
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 strict-mode
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 IPSG 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 IPSG static binding entry
or the DHCP snooping learned dynamic binding entry.
