  • 1.  RETH interfaces not getting created

    Posted 11-10-2021 13:55
    hi

    Here is the configuration:

    root@SRX1500# show interfaces reth0
    vlan-tagging;
    redundant-ether-options {
    redundancy-group 1;
    lacp {
    active;
    periodic slow;
    }
    }
    unit 0 {
    family ethernet-switching {
    interface-mode trunk;
    vlan {
    members [ vlan10 vlan120 ];
    }
    }
    }

    ================================
    But when you try to see the result in the operational mode:
    root@SRX1500# run show interfaces reth0
    error: device reth0 not found

    Even in "run show interface terse" command, its does not show any RETH interface.
    Also, the command "set chassis cluster reth-count 10" exists in the configuration.

    What could be the reason for RETH interface not getting created?

    Regards
    Saif

    Hello,

    I think you must set units as vlans, try configure like this example in reth interface:

    vlan-tagging; unit 10 { family bridge { interface-mode trunk; vlan-id 10; } unit 120 { family bridge { interface-mode trunk; vlan-id 120; }
    Post "run show configuration interfaces reth0"

    Please take a look at this article to understand l2 ethernet switching:

    Thanks, regards.

    Do you have the physical interfaces added to the reth interface?

    Also, I think you might be confusing reth (redundant ethernet) with ae (aggregated ethernet) we don't typically see lacp configured for reth interfaces this is typically used for the ae ones.  Are you trying to configure a redundant failover interface on a chassis cluster or a link aggregation group to increase bandwidth?
