Group of the VLAN Interface
Delete the corresponding DHCP Server
group of the VLAN interface
By default, no VLAN interface corresponds to any DHCP Server group.
When associating a VLAN interface to a new DHCP Server group, you can configure
the association without disassociating it from the previous group.
5.2.3 Configuring the Address Table Entry
To make the valid user with fixed IP address in the VLAN configured with DHCP Relay
pass the address validity check of DHCP security feature, you must add a static
address entry which indicates the correspondence between an IP address and an MAC
address.
If another illegal user configures a static IP address which is in conflict with the fixed IP
address of a valid user, the switch with DHCP Relay function enabled can identify the
valid user and reject the illegal user's request for binding the IP address with the MAC
address.
Perform the following configuration in System view.
