Figure 283 Trusted and untrusted ports
In a cascaded network as shown in Figure 284, configure each DHCP snooping device's ports
connected to other DHCP snooping devices as trusted ports. To save system resources, you can disable
the untrusted ports that are not directly connected to DHCP clients from generating DHCP snooping
entries.
