I'm preparing for JNCIS-SEC exam. I used junos-vsrx-12.1X47-D20.7-domestic image to create virtual machine in order to practice for the exam.

I am following this to configure the vsrx. When I do the following command :

set interfaces fxp0 unit 0 family inet dhcp client

and after doing commit and show system services dhcp client I got the following output

enter image description here

I am trying to create the following topology : enter image description here

The network adapters of the virtual machine are set up as follows network adapter 1: bridged network adapter 2: vmnet 4 network adapter 3: vmnet 5

I am working on a pc which is connected to local area network which uses Juniper switches. The port I am connected to might not be configured as dhcp-trust

why I am not obtaining an IP address ??


The selected answer solved the problem along with the following command :

set interfaces ge-0/0/0 unit 0 family inet dhcp 

instead of dhcp client in the previous command

When you are running the SRX stand-alone (eg: not clustered), the first port is ge-0/0/0. It's only when you switch the unit to a chassis cluster member that the interface becomes fxp0.


delete interfaces ge-0/0/0

rename interfaces fxp0 to ge-0/0/0

replace pattern fxp0 with ge-0/0/0


and you will be ready to go.
