    Can the 1-GE Mini-PIM be used in a reth bundle?  I know they do not support switching, but there's nothing in the docs that I could find that says it's not supported in a reth bundle.  Or are switching and redundant ethernet the same thing, in the context of a chassis cluster?

    Hi evt yes this should work.

    Odd. I was never able to get it to work. Whenever I tried to put a pair of these in a reth, the FPCs would just restart and never come back online.

    Hi, whats ever is the topology you are using please remember that Branch SRX support switching only on same module . If module changes then switching is not support inter module . It is always best practice to use reth on interfaces from same module , If you still want to use optical fiber instead of fiber then search for media converter (Fiber to Copper) and use built in interfaces instead of 1-GE Mini-PIM

    It's a pretty vanilla topology.  A pair of SRX220s clustered together, each with a 1-GE Mini-PIM in 2/0/0 and 5/0/0.  The Mini-PIMs aren't configured to perform switching using an swfab interface.  They were supposed to have each been a member in the same reth, consisting of just those two ports (ge-2/0/0 and ge-5/0/0).  As of now, I'm not using a reth, but rather just plain routing (separate subnets) on each interface and layer 3 protocols are taking care of the traffic failover in case one goes down.

    OK! You need to understand the basic architecture of SRX 210, it can contains only one Mini-PIM slot. In Branch SRX onboard interfaces are connected processor through internal ethernet switch and each WAN link (Mini-PIM) connected to processor through other ethernet switch. Now 2 interfaces from two different modules can not be part of reth as they belong to different switch and inter switch traffic processing require firewall inspection . Ref (Page 70 & 71 Oreilly.Junos.Security.Aug.2010.pdf).

    Got it.  I just didn't see anywhere in the docs that mention Mini PIMs can't be used in reths.
