DGS-3630 Layer 3 Stackable Managed Switch CLI Reference Guide Default By default, this option is disabled. 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 port 10. Switch# configure terminal Switch(config)# interface eth1/0/10 Switch(config-if)# ip ip-mac-port-binding strict Switch(config-if)# 60-3 show ip ip-mac-port-binding This command is used to display the IMPB configuration settings or the entries blocked by IMPB access control. show ip ip-mac-port-binding [interface INTERFACE-ID [, | -]] [violation] Parameters interface INTERFACE-ID , - violation (Optional) Specifies to display for the specified interface.
