Configure DHCP Failover failed. Error: 20010: The specified option does not exist

Question

Configure DHCP Failover failed. Error: 20010: The specified option does not exist

Peeyush Gupta 1

We have a Primary DHCP Server (2012 R2 Standard). We are trying to Configure a DHCP Failover with Server 2016. There are 3 Scopes. Two Scopes, we successfully managed to do the Failover. There is one Scope which is failing on the Failover (Configure Failover failed: Error: 20010. The specified option does not exist). I have checked "Set Predefined Options" and it does match on both Servers. Could somebody please assist here?

Answer 1

Hi ,

Please check whether you have one or more custom DHCP attributes. As picture below:

Please make sure you have created the same custom attributes on your partner server:

Then we should configure failover successful:

I have checked "Set Predefined Options" and it does match on both Servers.

Please post some screenshots to help us confirm the configuration.

Best Regards,
Candy

same here. TFTP is the culprit. I deleted the Option 150 : TFTP configured the failover then added the option again. This resolved it.
