    We got a EX3400 and would need to incorporate the configurations in EX2200 where ae is concerned:

     

    chassis {
    aggregated-devices {
    ethernet {
    device-count 1;
    }
    }
    alarm {
    management-ethernet {
    link-down ignore;
    }
    }
    auto-image-upgrade;
    }

    ...

    ge-0/0/20 {
    ether-options {
    802.3ad ae0;
    }
    }
    ge-0/0/21 {
    ether-options {
    802.3ad ae0;
    }
    }

    ......

    ae0 {
    description "LAG to Juniper Fw02.vlan20";
    unit 0 {
    family ethernet-switching {
    port-mode access;
    vlan {
    members svr;
    }
    }
    }
    }

     

    I was trying to configure ae in J-web, but I goth this error message:

    The configuration could not be locked.

    Error(s):
    'interface'

    1) XSTP : Interface ge-0/0/20 is not enabled for Ethernet Switching
    2) configuration check-out failed

     

    Can someone help me out?

     

    Appreciated.

    Hi Wayne,

     

    Looks like you have spanning tree configured on ge-0/0/20, which is now a in a lagg. 

    Delete the spanning tree configuration for both ge-0/0/20 and ge-0/0/21.

     

    show configuration protocols

    Not sure which version you are running but will be under rstp / vstp / mst. I do not use j-web but I assume there is a protocols section somwhere.

    Hi Wayne,

    Could you please provide the output of “ show configuration protocols” ? it might be that ge-0/0/20 is configured for spanning tree

    Below command will show what all has been configured for ge-0/0/20

    show configuration | match ge-0/0/20 | display set

    Regards,
    Jibu

    Hello Wayne

     

    Please compare the default configuration of interface ge-0/0/20 and ge-0/0/21 and make the configuration identical.

    You are seeing the error message only for ge-0/0/20 and not ge-0/0/21. Most probably you might have to enable the ethernet switching on the interfacege-0/0/20.

     

    Thanks

    Interfaces ge-0/0/20 and ge-0/0/20 could be enabled for spanning-tree since by default rstp is enabled for all interfaces.

     

    Remove the ports from spanning-tree and commit again.
