The display shows that, after IP Source Guard is enabled on OLT 3/0/1, the port obtains the dynamic 

entry generated by DHCP snooping. 

As shown in 

, Switch A connects to Client A and the DHCP server through interfaces 

VLAN-interface 100 and VLAN-interface 200 respectively. DHCP Relay is enabled on Switch A.  

Detailed requirements are as follows: 

z 

Client A (with the MAC address of 00-01-02-03-04-06) obtains an IP address from the DHCP 

server through DHCP Relay.  

z 

On interface VLAN-interface 100, enable the dynamic binding function to filter packets by using the 

generated DHCP Relay entries.
