Help, I got wrong assigned IP by DHCP server!!!

24 Apr

Posted by Jayce as Networking

In my lab environment, there are test server, PQIUHC and UUT. Both test server and PQIUHC have DHCP service running. Test server will assign 128.101.1.x IP to those connect to test network while PQIUHC will assign 129.101.1.x to those connect to UUT network.

One of my customer IM me for above problem. Her station get wrong assigned IP from test server when she plug in test network. She got 129.101.1.xx IP instead of 128.101.1.xx. Why she can get 129 UUT network IP? It is clear that one of the PQIUHC is listening at test network and assign IP to those connect to test network.

No need for me to teach more. Identify which PQIUHC is causing this issue. Unplug the network cable will solve the issue. Yeah!!! She get back 128.101.1.xx IP after that.

You will never want to unplug neither Test and PQIUHC network cable so often, so if u network switch support the below functionality, assign a private network area on the network switch just for the test server, then other for public use. so next time when the time you customer want to connect to the test server jz plug into the private area network port, else otherwise. Hope this will help

Actually, lab network is not that complicated. Just my user mistake plug into the wrong port during setting up new PQIUHC. By changing the port will do the thing…
