SRX

When I configure a trunk with LACP between an EX and a SRX the links drop and become inactive.  No activity appears when running show lacp statistics interface ae0 on either device either.  Both devices are running the latest firmware versions.  Any ideas?

SRX100

chassis {
    aggregated-devices {
        ethernet {
            device-count 1;
        }
    }
}
interfaces {
    fe-0/0/1 {
        fastether-options {
            802.3ad ae0;
        }
    }
    fe-0/0/2 {
        fastether-options {
            802.3ad ae0;
        }
    }
    ae0 {
        aggregated-ether-options {
            lacp {
                active;
            }
        }
        unit 0 {
            family ethernet-switching {
                port-mode trunk;
                vlan {
                    members default;
                }
            }
        }
    }
}

 EX2200

chassis {
    aggregated-devices {
        ethernet {
            device-count 1;
        }
    }
}
interfaces {
    ge-0/1/0 {
        ether-options {
            802.3ad ae0;
        }
    }
    ge-0/1/1 {
        ether-options {
            802.3ad ae0;
        }
    }
    ae0 {
        aggregated-ether-options {
            lacp {
                active;
            }
        }
        unit 0 {
            family ethernet-switching {
                port-mode trunk;
                vlan {
                    members default;
                }
            }
        }
    }
}

 Thanks!

Set the EX2200 to passive mode not active and see how you go.

No change unfortunately.  I've tried alternating the active/passive roles between both devices and running active/active and none of the configurations work.  Here's the output of show lacp statistics interfaces ae0 on the SRX (which is now active).

Aggregated interface: ae0
    LACP Statistics:       LACP Rx     LACP Tx   Unknown Rx   Illegal Rx
      fe-0/0/1                   0           0            0            0
      fe-0/0/2                   0           0            0            0

 Thanks!

Is ae0 bound to a security zone?

Okay I just tested this on my SRX100 & EX2200.

It seems you need to manually set the ports on the EX2200 to 100m (just the ports used for the ae interface).

So something like this:

ge-0/0/12 {
    ether-options {
        speed {
            100m;
        }
        802.3ad ae1;
    }
}
ge-0/0/13 {
    ether-options {
        speed {
            100m;
        }
        802.3ad ae1;
    }
}

Heh, I just came here to post the same result!  Do you know why the ae0 members appear to default to a static 1Gbps?  Thanks for your help!

Sorry no idea. I suspect it has something to do with ae needing the same link speed for both interfaces, so it is set statically. This is just a guess though!

I was just thinking about setting up a 2x4 interface ae link with an SRX100 to see if I can hit the CPU limit 😄
