    It looks like you are adding the interface to the incorrect vlan I assume that irb.411 would be under VLAN411_MGMT and not default.

    And you also need to create the interface itself under interfaces

    root@SPHARE# show vlans
    VLAN11_SRV {
    description ***SERVER-MGMT-VLAN***;
    vlan-id 11;
    }
    VLAN411_MGMT {
    vlan-id 411;
    l3-interface irb.411;
    }
    default {
    }
    
    interfaces 
    irb {
        unit 411 {
            family inet {
                address 10.0.1.1/24;
            }
        }
    }

    What if you add "vlan-id 0" here?

    A vlan id (not zero) is needed for an irb interface.  So you would need to assign some id for this vlan. 

    This can still have untagged interfaces as members of the vlan group with access mode assigned.
