DGS-1510 Series Gigabit Ethernet SmartPro Switch CLI Reference Guide
Command Mode
Interface Configuration Mode.
Command Default Level
Level: 12.
Usage Guideline
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 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.
Example
This example shows how to enable the strict-mode IMPB access control on eth3/0/10.
