Issue Description

After IAM has configured the DHCP address allocation, the PC is still in the old network segment.

Handling Process

1. The IAM device acts as a gateway and enables the DHCP function.
2. Due to the customer’s business needs, after modifying the LAN port address network segment (modified from 172.37.84.1 to 172.37.83.1), the corresponding DHCP configuration has also been modified.
3. The address assigned by the PC is found to be the original network segment.
4. Type ipconfig/release;ipconfig/renew on the PC to regain the address but still not working.
5. ipconfig/all on the PC, check the DHCP server address is 172.37.84.15

Root Cause

There are other devices on the intranet configured as DHCP server.

Solution

Locate the IP address 172.37.84.15 as shown in the above figure and stop its DHCP function.
