Enable Ethernet switching mode on Juniper Firewals SRX 300 Series

In Q1 2016 Juniper has released new firewall platform SRX 300 series which replaces SRX 200 series. Initial software releases did not support Ethernet switching on SRX 300 series.

With new software release 15.1X49-D50, Juniper adds Ethernet switching support. This means that you can now use ports on firewall as a switch 🙂

To enable Ethernet switching mode use following command:

set protocols l2-learning global-mode switching

After changing the mode, you must reboot firewall for configuration to take affect.To verify that mode has changed use following command:

show ethernet-switching global-information

Global mode should be set to “Switching”
