  • 1.  SRX240 (HA) <-> EX4200 (cluster) cannot ping one another

    Posted 11-15-2014 09:43

    Hi there,

     

    I have four cables connecting two SRX240s (in a HA cluster) to two EX4200s (also clustered). The goal was to have aggregation & failover.

     

    On the SRX side, they are all in reth0. On the EX side, they are all in ae0.

     

    I cannot ping across from one device's IP to the other. Am I going about this the right way? Many thanks in advance for any help.

     

    James

     

    EX configuration:

     

    chassis {
    aggregated-devices {
    ethernet {
    device-count 1;
    }
    }
    auto-image-upgrade;
    }


    interfaces {

    ...

    ge-0/0/22 {
    ether-options {
    802.3ad ae0;
    }
    }
    ge-0/0/23 {
    ether-options {
    802.3ad ae0;
    }
    }

    ...

    ge-1/0/22 {
    ether-options {
    802.3ad ae0;
    }
    }
    ge-1/0/23 {
    ether-options {
    802.3ad ae0;
    }
    }

    ....

    ae0 {
    aggregated-ether-options {
    minimum-links 1;
    lacp {
    active;
    }
    }
    unit 0 {
    family inet {
    address 1.50.73.194/28;
    }
    }
    }

    }

    You need to have 2 different ae interfaces on EX side. Below KB explains the scenario.
