  • 1.  LAG between M7i and Extreme networks switch.

    Posted 07-29-2009 07:28

    I need configure LAG between M7i and Extreme networks switch.

    My ae0 interface is down. Analogical configuration with EX3200 work without problem.

     

    Please, give me any information about interoperability with Extreme's switches in mind of LAG.

    Thanks!!

    Hi,

    Here is a config that I did that on the M7i side:
     

    chassis {
        aggregated-devices {
            ethernet {
                device-count 1;
            }
        }
    }
    interfaces {
        ge-0/1/0 {
            gigether-options {
                802.3ad ae0;
            }
        }
        ge-1/3/0 {
            gigether-options {
                802.3ad ae0;
            }
        }
        ae0 {
            vlan-tagging;
            aggregated-ether-options {
                minimum-links 1;
                link-speed 1g;
            }
            unit 0 {   
                vlan-id 1;
                family inet {
                    address 10.0.0.1/30;
                }
            }
        }

    And on the Extreme side:

    enable sharing 1:1 grouping 1:1-2 algorithm port-based

    configure vlan Default add ports 1:1 tagged
     
    configure vlan Default ipaddress 10.0.0.2 255.255.255.252

     

    this config is done with tagging and you can see that I used two different PIC cards on the M7i side.

    this was the status of the M7i side:

    Thanks!! But we need configure on Extreme x650.

    Quote from documentation:

      "You cannot configure port-based load sharing on the Summit X450a, X450e, X350, X250e, and X150 series

    switches (whether or not included in a SummitStack). "

     

    x650 has not this configuration option also. 

     

    We have configured your solution on the module Extreme switch. It work without problem. But, when we have configured

    enable sharing 2:1 grouping 2:1-2 algorithm address-based

    Juniper's side interface ae0 have went to down. 

    We have solved this issue. 
    On the Extreme switch (non - modular) need type command: enable sharing 17 grouping 16-18 algorithm address-based L3_L4 lacp
    "lacp" - is needed. 
    Thanks for all

    We have solved this issue. 

    On the Extreme's non-modular  switch need type 

    enable sharing 17 grouping 16-18 algorithm address-based L3_L4 lacp

    "lacp" - is key word

     

    Thanks for all.
