This guide shows how to jump to the VTY of the pfe on Juniper SRX branch firewalls (srx100 to srx650).

The SRX branch devices have a virtual (or software) PFE. It is formed from a flowd daemon running on the routing engine unix and taking 100% cpu due to polling mode.

The Junos VTY is a special interface that allows interaction with different hardware or software components in Juniper products running the Junos operating system.

On the SRX, it can be used to connect to Packet forwarding engines running on SPUs, IOCs, CPP and so on.
