DHCP exclude-address on QFX5100

‎01-08-2017 09:06 AM

Hi

 

I need to replace my ex switch with QFX5100. All the DHCP configuration onEX switch is replicated to QFX5100. The only command i am unable to find in QFX is DHCP exclude-address command. Can anyone help. The EX command is as below.

 

set system services dhcp pool 10.121.71.128/25 exclude-address 10.121.71.232

 

Regards

 

Tayyab

I would guess that this function hasn't been implemented on DHCPD on QFX. You need to use JDHCPD instead which is the way to go moving forward.

 

Here is a configuration example for JDHCPD-style configuration: https://www.juniper.net/documentation/en_US/junos16.1/topics/task/configuration/dhcp-server-cli-els....

 

You can then configure an excluded address via something like this:

set access address-assignment pool XXX family inet excluded-address 10.253.12.45

Please note: You have to remove all existing DHCPD configuration to change to JDHCPD as these cannot run at the same time.

 

Hope this helps.
