Configuration steps

Step 1 Configure global DHCP Snooping.

Alpha-A28E#config

Alpha-A28E(config)#ip dhcp snooping

Step 2 Configure trust interface.

Alpha-A28E(config)#interface port 1

Alpha-A28E(config-port)#ip dhcp snooping trust

Alpha-A28E(config-port)#quit

Step 3 Configure DHCP Snooping to Option 82 function and configure the field Option 82.

Alpha-A28E(config)#ip dhcp snooping information option

Alpha-A28E(config)#ip dhcp information option remote-id string user01

Alpha-A28E(config)#interface port 3

Alpha-A28E(config-port)#ip dhcp information option circuit-id alpha-a28e

Checking results

Use the show ip dhcp information option command to check whether DHCP snooping is

correctly configured.

Alpha-A28E#show ip dhcp information option
