Hello.


I want to know if I can configure OPTION 3 for the IP address from an interface address pool. I tried but this message was displayed:


[interface-Vlan30]dhcp server option 3 ip-address 172.18.4.50
Error: This option cannot be configured using this command.


I've already selected the interface address pool.

 

What's going on?

Hi @lucasSaave!

To assign the gateway IP for an interface based address pool, please use command dhcp server gateway-list, but this command is not supported in eNSP.

Thanks!

Hi @lucasSaave
(And I an Router I have only one DHCP server o for each interface I have a different Server?) sorry, but I didn't understand your meaning. Could you please clarify it?

Every interface has its unique DHCP Server or is there only one DHCP Server?

@lucasSaave
well, in my opinion, DHCP server on the router is similar as the thread in the operation system. You can consider a DHCP server enabled as a thread.

As we talked, the corresponding command is not supported in eNSP, if you want to modify the gateway ip address, you can enable a ip address pool, while it's allowed to modify the gateway address in ip pool view.
