I'm fairly new to the Juniper switching and am running into something very odd. I have configured four EX3400 switches into a virtual chassis using the pre-configured QSFP+ ports. The installation has gone without a hitch and I can see all of the ports available in the show interfaces command except for the SFP+ ports. The only configuration I have done for the Virtual Chassis is to give membership priority to ensure the correct switch will become master.
I have configured the SFP+ ports to be an Aggregate link to connect back to our corporate network but because they are not available in the interfaces they are not becoming active. Could anyone advise why this may be? I have been searching the Juniper forums for a few hours now and have come up short with any real answers.
If you don't see the interfaces with the show interfaces terse that means that the SFP+ might be not recognized. It could also be that these ports are configured as vc-ports. Check with the command show virtual-chassis vc-ports to see if they are listed as vc-ports. If they are then you need to delete the vc-port and after that you will see the interface listed.
Uplink ports are usually considered as separate pic. For example, assuming you are using a 24T model, the copper ports will be from ge-0/0/0 to ge-0/0/23 (member 0) and the front SFP+ ports will be ge-0/2/0 through ge-0/2/3. Following commands can help you out:
Apologies for the delay, after some back and forth on the platform it turned out I was getting confused as I wasn't seeing the ge-0/2/[0-3] in the show interfaces command. The issue ended up being with the SFPs we were using which were Single Mode 9/125 SFPs which weren't supported once replaced the configuration I had already set started working.
