  • 1.  LAG between SRX240H and Extreme networks switch Summit-X460 cluster

    Posted 05-29-2013 23:29

    I need to configure LAG between SRX240H and Extreme networks switch Summit-X460 cluster.

    My ae0 interface is up. The members of the LAG are ge-0/0/1 and ge-0/0/2. But only one interface ge-0/0/1 is up. ge-0/0/2 is down. The part of configuration is:

     

    ...

    chassis {

        aggregated-devices {

            ethernet {

                device-count 1;

            }

        }                                  

    }

    interfaces {

    ...

        ge-0/0/1 {

            gigether-options {

                802.3ad ae0;

            }

        }

        ge-0/0/2 {

            gigether-options {

                802.3ad ae0;

            }

        }

        ae0 {

            description Link_to_Extreme_X460_cluster;

            aggregated-ether-options {

                minimum-links 1;

                link-speed 1g;

            }

        }

    }

    ...

     

    The state of interfaces:

     

    user> show interfaces terse | match ae
    ge-0/0/1.0 up up aenet --> ae0.0
    ge-0/0/2.0 up down aenet --> ae0.0
    ae0 up up
    ae0.0 up up eth-switch

     

    Configuration of Summit-X460 cluster is:

     

    ...

    enable sharing 1:28 grouping 1:28, 2:20 algorithm address-based L2 lacp

    ...

     

    The state of LAG:

    Custom Algorithm Configuration: ipv4 L3-and-L4, xor

    Note - Layer 4 ports are not used for distribution for traffic ingressing

           ports on X450-24t and X450-24x switches.

    Number of load sharing trunks: 1

    ================================================================================

    Actor Flags: A-Activity, T-Timeout, G-Aggregation, S-Synchronization

                 C-Collecting, D-Distributing, F-Defaulted, E-Expired

     

    The situation is the same with configuration of 2 interfaces from one Slot, for exaplle 1:27-28.

    Could you please advise me a direction to resolve this problem?

    Thanks!!

    What happens if you enable LACP?

    Show the results of user> show interfaces ge-0/0/1 and 2 extensive

    Excuse me all! Juniper SRX devices definitely work with Extreme switches either standalone or stacked by either static LAG or LACP.  I connected my two devices (SRX240 and Extreme switch stack) by two cables, but one of them was not ethernet type. It was telephone type RJ45 with all of eight used wires. I have replaced this cable by new one and the problem was resolved, but I wasted a lot of time to resolve this by program method. %-) Below is my 100% working configuration with static LAG. Hope it helps somebody.

     

    Juniper SRX240:

     

    ...

    chassis {

        aggregated-devices {

            ethernet {

                device-count 1;

            }

        }

    }

    interfaces {

    ...

        ge-0/0/1 {

            gigether-options {

                802.3ad ae0;

            }

        }

        ge-0/0/2 {

            gigether-options {

                802.3ad ae0;

            }

        }

    ...

        ae0 {

            description Link_to_Extreme_X460_cluster;

            aggregated-ether-options {

                minimum-links 1;

                link-speed 1g;

            }

        }

    }

    ...

     

    The state of interfaces:

     

    user@SRX240> show interfaces terse | match ae

    ge-0/0/1.0              up    up   aenet    --> ae0.0

    ge-0/0/2.0              up    up   aenet    --> ae0.0

    ae0                        up    up

    ae0.0                     up    up   eth-switch

     

     

    Extreme Summit X460-24 stack:

     

    enable sharing 1:28 grouping 1:28, 2:20 algorithm address-based L2

     

    (Extreme did it shortly and clearly %-) but not user friendly)

     

    The state of the LAG:

     

    Slot-1 X460.2# sh sharing

    Load Sharing Monitor

    Config    Current    Agg       Ld Share    Ld Share  Agg   Link    Link Up

    Master    Master     Control   Algorithm   Group     Mbr   State   Transitions

    ==============================================================================

      1:28   1:28        Static    L2          1:28       Y      A        2

                                            L2          2:20       Y      A        2

    ==============================================================================

    Link State: A-Active, D-Disabled, R-Ready, NP-Port not present, L-Loopback

    Load Sharing Algorithm: (L2) Layer 2 address based, (L3) Layer 3 address based

                            (L3_L4) Layer 3 address and Layer 4 port based

                            (custom) User-selected address-based configuration

    Custom Algorithm Configuration: ipv4 L3-and-L4, xor

    Number of load sharing trunks: 3

    Slot-1 X460.3#

     

    The configuration with LACP LAG also works. I checked it.
