Hi,

I am facing an issue with Juniper SRX 1600 for SFP and SFP + port.  SFP ports are not showing in cli while entering the command show interface terse.

PIC 1 and PIC 2 are showing as online but the ports are not listing.

And also from where we can see and download JTAC recommended JUNOS for SRX 1600 Firewall Model.

Do you have optics inserted yet?

The show interfaces will not display without an optic since they are multi speed ports and won't have the GE/XE/ET interface notation until the optic is inserted asserting a speed for the port.

Downloads are on the support site.  The SRX1600 only has the current version option as a new release.

What optics do you have in which port ?  Do they show up in show chassis hardware ?

I ran into this with the SRX1600 too where I had inserted SFP+ optics into PIC1 ports 0 and 1 and they wouldn't list in the hardware, nor after a reboot.

My best guess was that because PIC 1 is SFP28 ports supporting up to 25Gbps optics that my SFP+ weren't forward compatible with them. I ended up moving my optics (SFP+-10G-SR and LR) to the PIC 2 ports instead which works fine (and suits me better leaving the SFP28's free for future expansion we'll probably populate them directly with 25Gbps optics) 

Hi ChrisLee,

By default, PIC 1 operates at 25G. To enable visibility and configuration of the xe-0/1/0 and xe-0/1/1 ports, you must change the PIC speed mode using the following command: set chassis fpc 0 pic 1 pic-mode "1G/10G/25G"."
