DHCP: Using option50

dgaikwad · ‎11-25-2019

Hi Experts,
What are the use cases where DHCP option50 is used?
What are the benefits of using option50?
Reason being that, when checking the infrastucture, I see that the wired endpoints are sending the option50 while the same is not being sent for wireless endpoints?

Is there a difference the way WLC and switches work with DHCP?

- DHCP option 50 is used to let clients request a specific IP address ; normally this will not be needed , except in special use cases where the client gets the same ip address again. If you see it happen on your wired network, then check it's DHCP server configuration, perhaps this was activated where normally it is not needed.

Thanks for the quick reply.
Enabling this option, would it cause delay in assigning IP addresses to the endpoints?

Since, we are seeing a delay of about 90 secs for the IP address to be assigned to the endpoint when it connects to the wired network.
