DGS-1250 Series Gigabit Ethernet Smart Managed Switch CLI Reference Guide Command Mode Interface Configuration Mode. 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)# 30-3 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 the interfaces to be displayed. (Optional) Specifies a series of interfaces or separates a range of interfaces from a previous range. No space is allowed before or after the comma. (Optional) Specifies a range of interfaces. No space is allowed before or after the hyphen. (Optional) Specifies to display the blocked entry. Default None. Command Mode EXEC Mode. Usage Guideline Use this command to display the IMPB configuration or use the show ip ip-mac-port-binding violation command to display the entries blocked because of the IMPB check violation. 237

DGS-1250 Series Gigabit Ethernet Smart Managed Switch CLI Reference Guide
237
Command Mode
Interface Configuration Mode.
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)#
30-3
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
(Optional) Specifies the interfaces to be displayed.
,
(Optional) Specifies a series of interfaces or separates a range of interfaces from
a previous range. No space is allowed before or after the comma.
-
(Optional) Specifies a range of interfaces. No space is allowed before or after the
hyphen.
violation
(Optional) Specifies to display the blocked entry.
Default
None.
Command Mode
EXEC Mode.
Usage Guideline
Use this command to display the IMPB configuration or use the show ip ip-mac-port-binding violation command to
display the entries blocked because of the IMPB check violation.
