    Hi,

    I have used successfully SRX cluster in a totally weird setup for 10 years (with multi-link ospf to internal routers that kind of thing) and it was working flawlessly.
    Now i'm trying to setup a simpler network and ... well i'm here so ;)

    Basically i have:
     * one simple user switch (no ha, no stack), with two vlans: user and management (for the switch and for the wireless setup)
     * another switch (a stack really), with 6 vlans: the same management vlan and five others vlans

    I want both 'switch' to have a multi-link uplink on each so  i followed what seemed to be the "correct" way: one reth0 per switch with port on both units and two corresponding port-channels on the switch sides.

    set interfaces ge-0/0/3 gigether-options redundant-parent reth0
    set interfaces ge-0/0/4 gigether-options redundant-parent reth0
    set interfaces ge-0/0/8 gigether-options redundant-parent reth1
    set interfaces ge-0/0/9 gigether-options redundant-parent reth1
    set interfaces ge-0/0/10 gigether-options redundant-parent reth1
    set interfaces ge-0/0/11 gigether-options redundant-parent reth1
    set interfaces ge-0/0/12 gigether-options redundant-parent reth0
    set interfaces ge-0/0/13 gigether-options redundant-parent reth0


    set interfaces ge-5/0/3 gigether-options redundant-parent reth0
    set interfaces ge-5/0/4 gigether-options redundant-parent reth0
    set interfaces ge-5/0/8 gigether-options redundant-parent reth1
    set interfaces ge-5/0/9 gigether-options redundant-parent reth1
    set interfaces ge-5/0/10 gigether-options redundant-parent reth1
    set interfaces ge-5/0/11 gigether-options redundant-parent reth1
    set interfaces ge-5/0/12 gigether-options redundant-parent reth0
    set interfaces ge-5/0/13 gigether-options redundant-parent reth0

    set interfaces reth0 native-vlan-id 1
    set interfaces reth0 redundant-ether-options redundancy-group 1
    set interfaces reth0 redundant-ether-options minimum-links 1
    set interfaces reth0 redundant-ether-options lacp passive
    set interfaces reth0 redundant-ether-options lacp periodic slow
    set interfaces reth0 unit 0 family ethernet-switching interface-mode trunk
    set interfaces reth0 unit 0 family ethernet-switching vlan members Vl_Users
    set interfaces reth0 unit 0 family ethernet-switching vlan members Vl_Management


    set interfaces reth1 native-vlan-id 1
    set interfaces reth1 redundant-ether-options redundancy-group 1
    set interfaces reth1 redundant-ether-options minimum-links 1
    set interfaces reth1 redundant-ether-options lacp passive
    set interfaces reth1 redundant-ether-options lacp periodic slow
    set interfaces reth1 unit 0 family ethernet-switching interface-mode trunk
    set interfaces reth1 unit 0 family ethernet-switching vlan members Vl_Management
    set interfaces reth1 unit 0 family ethernet-switching vlan members Vl_Srv1
    set interfaces reth1 unit 0 family ethernet-switching vlan members Vl_Srv2
    set interfaces reth1 unit 0 family ethernet-switching vlan members Vl_Srv3
    set interfaces reth1 unit 0 family ethernet-switching vlan members Vl_Srv4
    set interfaces reth1 unit 0 family ethernet-switching vlan members Vl_Srv5

    however when ports are enabled on both units both port-channels came up and the switches start reporting mac adresses flappings and most of the time the cpu of the cluster start to spike ...

    It look like it's because i'm using ethernet-switching ? i don't get why all ports come up in this configuration ...
    any suggestions ?
