After DHCP snooping is enabled, all the interfaces on the device are untrusted interfaces by default. In this case, you need to use dhcp snooping trusted command to set the status of the interfaces connected to the DHCP server to trusted. Otherwise, the DHCP Reply messages sent from the DHCP server are discarded and users connected to the device cannot obtain IP addresses from the DHCP server.
