Displaying And Maintaining Ip Source Guard; Ip Source Guard Configuration Examples; Static Binding Entry Configuration Example - 3Com 4500G Family Configuration Manual

To implement dynamic binding in IP source guard, make sure that DHCP snooping or DHCP Relay
is configured and works normally. For DHCP configuration information, refer to DHCP
Configuration in the System Volume.
The dynamic binding function can be configured on Ethernet ports and VLAN interfaces.
A port takes only the latest dynamic binding entries configured on it.

Static Binding Entry Configuration Example

Network requirements
As shown in Figure
GigabitEthernet 1/0/1 of Switch B respectively, Host C is connected to port GigabitEthernet 1/0/2 of
Switch A, and Switch B is connected to port GigabitEthernet 1/0/1 of Switch A.
Configure static binding entries on Switch A and Switch B to meet the following requirements:
On port GigabitEthernet 1/0/2 of Switch A, only IP packets from Host C can pass.
On port GigabitEthernet 1/0/1 of Switch A, only IP packets from Host A can pass.
On port GigabitEthernet 1/0/2 of Switch B, only IP packets from Host A can pass.
On port GigabitEthernet 1/0/1 of Switch B, only IP packets from Host B can pass.
