Usage guidelines
After you enable DHCP snooping globally on the device, trusted ports forward responses from DHCP servers and untrusted ports discard responses. This mechanism ensures that DHCP clients obtain IP addresses from authorized DHCP servers.
When DHCP snooping is disabled globally, all ports on the device can forward responses from DHCP servers.
Examples
# Enable DHCP snooping globally.
<Sysname> system-view [Sysname] dhcp snooping enable
