3. In case of SRX only one device runs at a time and ports of other SRX (slave) do not access traffic at all as long as it see the master is up via heartbeat.
This is true with regards to RETH interfaces, but any interface that is not part of a reth group on the slave SRX will function all the time. The SRX HA works with RE being up only on the master, while the PFE (which is what all interfaces use) is live on both systems all the time. In fact, you can make a reth group to have it's master interface on the slave SRX, depending on your redundancy group priorities. Also, I'd recommend assigning more than one interface for FAB links, providing your SRXes have the spares to use. Kareem. -- Abdulkareem H.
