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