  • 1.  Errors when creating an aggregated link

    Posted 01-28-2009 04:41

    Dear all,

     

    When I'm creating an aggregated link of 2Gbpbs towards another switch I get the following error:

     

    root@juniper_switch_1# commit check
    [edit interfaces ge-0/0/22 ether-options]
      '802.3ad'
         ae child device link-mode setting is not allowed
    [edit interfaces ge-0/0/23 ether-options]
      '802.3ad'
         ae child device link-mode setting is not allowed
    [edit interfaces ae0]
      'aggregated-ether-options'
        minimum-links is greater than the num of links configured for this interface
    error: configuration check-out failed

     

     The strange thing is that the config statements are exactly the same as the other switch where it is supposed to connect to and there I don't get these error messages.

     

    Config:

     

     }
    ge-0/0/22 {
        ether-options {
            link-mode full-duplex;
            speed {
                1g;
            }           
            802.3ad ae0;
        }
    }
    ge-0/0/23 {
        ether-options {
            link-mode full-duplex;
            speed {
                1g;
            }
            802.3ad ae0;
        }

    }
    ae0 {
        aggregated-ether-options {
            minimum-links 2;
        }              
    }

    aggregated-devices {
        ethernet {
            device-count 1;
        }
    }

     

    These are the commands I used to configure the LAG:

     

     edit chassis
    set aggregated-devices ethernet device-count 1

    edit interfaces
    set ae0 aggregated-ether-options minimum-links 2

    set ge-0/0/22 ether-options 802.3ad ae0
    set ge-0/0/23 ether-options 802.3ad ae0

    set ge-0/0/22 ether-options speed 1g
    set ge-0/0/23 ether-options speed 1g

    dele ge-0/0/22 unit 0
    dele ge-0/0/23 unit 0

     

    Kind Regards,

     

    Eno

    The error messages explain what the problem is - you have "link-mode" settings in the ethernet interfaces, which is not permitted.  Remove those statements and you should be good.

     

    The third error is popping up because after the LAG kicks out ge-0/0/22 and ge-0/0/23, there aren't enough interfaces left to satisfy the minimum-links config of ae0.

    Thanks for the feedback, it works now. Have to get out off this Cisco state of mind 🙂

    I am trying to configure link-aggregation between juniper ex4200 and 3com 5500 switch. I have also configured virtual-chassis setup with two ex4200 switches. When the link to the 3com 5500 from the master ex4200 is up then the connections works fine. When that goes down the connection is not getting shifted to  the backup ex4200.... Can you please let me know if you have any sample configuration for this setup?
