Re: srx340 as a switch and gateway router

Hi,

You will still be able to use it as the SRX240H2 (which is EoL, you can buy it from distributor stock as long as it last).

15.1X49-D40 re-adds support for ethernet switching:

—Starting with Junos OS Release 15.1X49-D40, the enhanced Layer 2 transparent bridge mode and switching mode features are supported on SRX300, SRX320, SRX340, SRX345, and SRX550 devices.
