Take V300R019 as an example. Perform the following steps to solve the problem:

A DHCP client broadcasts a DHCP Discover message. When there are multiple DHCP servers including bogus DHCP servers on a network segment, the DHCP client accepts only the first received DHCP Offer message and therefore may obtain an unexpected IP address from a bogus DHCP server. To ensure that a client obtains an IP address from the correct DHCP server, configure DHCP snooping.

When receiving DHCP packets from a DHCP client or DHCP server, a DHCP snooping-enabled Fit AP records DHCP/6/SNP_RCV_MSG logs. You need to configure the Fit AP to send logs to the log host before viewing the DHCP/6/SNP_RCV_MSG logs on the log host. Ensure that the Fit AP and log host are routable to each other.
