Switching

Hi guys, I have an unusual issue. I am configuring link aggregation on my EX3400 for the first time. I am experiecing the following issue. Can someone please have a look and tell me what am I missing? Thanks

Following is the configuration with the error message at the end.

SW_Lab# show interfaces ge-0/0/46
description "BACKUP ae0";
ether-options {
    802.3ad ae0;
}

SW_Lab# show interfaces ge-0/0/47
description "BACKUP ae0";
ether-options {
    802.3ad ae0;
}

SW_Lab# show interfaces ae0
description BACKUP;
aggregated-ether-options {
    minimum-links 1;
    link-speed 1g;
    lacp {
        active;
        periodic fast;
    }
}
unit 0 {
    family ethernet-switching {
        interface-mode trunk;
        vlan {
            members 100;
        }
    }
}

Can you post the output of

show interfaces ge-0/0/46 | display inheritence

Or your whole config. It sounds like your member interfaces are inherting something from a group or interface-range setting.
