Networking requirements
As shown in Figure 3-9, the switch is used as the DHCP Snooping device. The network
requires DHCP clients to get IP address from a legal DHCP server and supports Option82 to
facilitate client management; you can configure circuit ID sub-option information on Port 3 as
alpha-a28e, and remote ID sub-option as user01.
