Hi DJfrozen, what error are you seeing when committing?

​@@frozenvsf This thread on reddit appears to explain the issue you're encountering: www.reddit.com/r/Juniper/comments/xuq08h/comment/iqwzcv5/

[@jongreenit]

Copied from Reddit: The reason this error is occurring is that you're attempting to commit configuration commands that are used in both the JDHCPd (new style) and DHCPd (old style). If you need to use the "old-style" server and also need an interface to be a DHCP client, you use: set interfaces ge-0/0/0 unit 0 family inet dhcp-client This is deprecated now, but pre-ELS boxes (

Can this be done on an ex4300?

[@jongreenit]

GM Alfredo, yes the ex4300 can also be configured as a DHCP server. This video references the new way of configuring DHCP on Juniper. Additionally you can reference the following Juniper KB article for examples of how to configure DHCP on Legacy EX series devices if applicable to your environment: supportportal.juniper.net/s/article/EX-Example-Configuring-an-EX-Series-switch-as-a-DHCP-server-including-gateway-DNS-and-others?language=en_US

Subscribed your channel today!

[@DavidRodriguez-oh2ng]

Can you please do the same but instead of using a QFX, could you try a vMX?

[@jongreenit]

The dhcp configuration will be the same for either platform

[@lokeshchand8562]

thank you sir from nepal

[@monoham1]

doesnt work. gives ```cant find dhcp server``` in the VPC config is like set vlans BLUE vlan-id 100 set vlans BLUE l3-interface irb.10 set access address-assignment pool BLUE family inet network x.y.11.0/24 set access address-assignment pool BLUE family inet range range-1 low x.y.11.10 set access address-assignment pool BLUE family inet range range-1 high x.y.11.224 set access address-assignment pool BLUE family inet dhcp-attributes router x.y.11.1 set interfaces ge-0/0/0 unit 0 family ethernet-switching interface-mode access set interfaces ge-0/0/0 unit 0 family ethernet-switching vlan members 100

[@jongreenit]

Apologies, It appears this message was held for review. Are you still encountering an issue? from the config above I don't see the irb interface configured to distribute IP addresses via DHCP (5:18)
