To check whether a Juniper firewall is in routing mode or switching mode, you can use the following commands in the CLI (Command Line Interface):

  1. Log in to the Juniper firewall using the CLI.
  2. Enter the following command to display the current mode:

Command: show chassis routing-engine

If the output displays the following line:

then the firewall is operating in routing mode.

If the output displays the following line:

then the firewall is operating in switching mode.

Note: Some Juniper firewalls can operate in both routing and switching modes simultaneously, so it’s possible for the output to show both routing and switching information.
