According to the exhibit, which is a configuration snippet of the SRX Series device, the global mode for the device is set to switching mode. This means that the device is operating as a Layer 2 switch and does not apply any security policies to the traffic between hosts in the same broadcast domain1. Therefore, the traffic between two hosts in the same broadcast domain are not matching any security policies.
To solve this problem, the user should change the global mode to transparent bridge mode. This means that the device will operate as a Layer 2 transparent bridge and apply security policies to the traffic between hosts in the same broadcast domain2. This will allow the user to enforce security policies based on the source and destination IP addresses, ports, and protocols of the traffic.
To change the global mode to transparent bridge mode, the user should use the following command:
set protocols l2-learning global-mode transparent-bridge
This command will set the global mode for the SRX Series device as Layer 2 transparent bridge mode. After changing the mode, the user must reboot the device for the configuration to take effect2.
