There are two commands for checking the traffic on an interface and their use can be confusing as they are simply a different order for the same words.
monitor traffic interface - as you can see from your testing, this command only shows traffic that terminates on the SRX router itself such as the vpn that you see.

monitor interface traffic - this is the command to see the transit traffic coming in one interface on and out another on the device.

Subject: how to see the traffic from reth interface
When we apply the monitor traffic interface reth3.0, we don't see the traffic that passes through this interface. We can see the VPN traffic, but the security sessions that are already up don't appear when we apply the monitor command. Do you have any ideas?
thanks
