    app-fcoe-flags

    NMSettingDcbFlags (uint32)

Specifies the NMSettingDcbFlags for the DCB FCoE application. Flags may be any combination of NM_SETTING_DCB_FLAG_ENABLE (0x1), NM_SETTING_DCB_FLAG_ADVERTISE (0x2), and NM_SETTING_DCB_FLAG_WILLING (0x4).

    app-fcoe-mode

    string

    "fabric"

The FCoE controller mode; either "fabric" (default) or "vn2vn".

    app-fcoe-priority

    int32

    -1

The highest User Priority (0 - 7) which FCoE frames should use, or -1 for default priority. Only used when the "app-fcoe-flags" property includes the NM_SETTING_DCB_FLAG_ENABLE (0x1) flag.

    app-fip-flags

    NMSettingDcbFlags (uint32)

Specifies the NMSettingDcbFlags for the DCB FIP application. Flags may be any combination of NM_SETTING_DCB_FLAG_ENABLE (0x1), NM_SETTING_DCB_FLAG_ADVERTISE (0x2), and NM_SETTING_DCB_FLAG_WILLING (0x4).

    app-fip-priority

    int32

    -1

The highest User Priority (0 - 7) which FIP frames should use, or -1 for default priority. Only used when the "app-fip-flags" property includes the NM_SETTING_DCB_FLAG_ENABLE (0x1) flag.

    app-iscsi-flags

    NMSettingDcbFlags (uint32)

Specifies the NMSettingDcbFlags for the DCB iSCSI application. Flags may be any combination of NM_SETTING_DCB_FLAG_ENABLE (0x1), NM_SETTING_DCB_FLAG_ADVERTISE (0x2), and NM_SETTING_DCB_FLAG_WILLING (0x4).

    app-iscsi-priority

    int32

    -1

The highest User Priority (0 - 7) which iSCSI frames should use, or -1 for default priority. Only used when the "app-iscsi-flags" property includes the NM_SETTING_DCB_FLAG_ENABLE (0x1) flag.

    priority-bandwidth

    array of uint32

    [0, 0, 0, 0, 0, 0, 0, 0]

An array of 8 uint values, where the array index corresponds to the User Priority (0 - 7) and the value indicates the percentage of bandwidth of the priority's assigned group that the priority may use. The sum of all percentages for priorities which belong to the same group must total 100 percents.

    priority-flow-control

    array of uint32

    [False, False, False, False, False, False, False, False]

An array of 8 boolean values, where the array index corresponds to the User Priority (0 - 7) and the value indicates whether or not the corresponding priority should transmit priority pause.

    priority-flow-control-flags

    NMSettingDcbFlags (uint32)

Specifies the NMSettingDcbFlags for DCB Priority Flow Control (PFC). Flags may be any combination of NM_SETTING_DCB_FLAG_ENABLE (0x1), NM_SETTING_DCB_FLAG_ADVERTISE (0x2), and NM_SETTING_DCB_FLAG_WILLING (0x4).

    priority-group-bandwidth

    array of uint32

    [0, 0, 0, 0, 0, 0, 0, 0]

An array of 8 uint values, where the array index corresponds to the Priority Group ID (0 - 7) and the value indicates the percentage of link bandwidth allocated to that group. Allowed values are 0 - 100, and the sum of all values must total 100 percents.

    priority-group-flags

    NMSettingDcbFlags (uint32)

Specifies the NMSettingDcbFlags for DCB Priority Groups. Flags may be any combination of NM_SETTING_DCB_FLAG_ENABLE (0x1), NM_SETTING_DCB_FLAG_ADVERTISE (0x2), and NM_SETTING_DCB_FLAG_WILLING (0x4).

    priority-group-id

    array of uint32

    [0, 0, 0, 0, 0, 0, 0, 0]

An array of 8 uint values, where the array index corresponds to the User Priority (0 - 7) and the value indicates the Priority Group ID. Allowed Priority Group ID values are 0 - 7 or 15 for the unrestricted group.

    priority-strict-bandwidth

    array of uint32

    [False, False, False, False, False, False, False, False]

An array of 8 boolean values, where the array index corresponds to the User Priority (0 - 7) and the value indicates whether or not the priority may use all of the bandwidth allocated to its assigned group.

    priority-traffic-class

    array of uint32

    [0, 0, 0, 0, 0, 0, 0, 0]

An array of 8 uint values, where the array index corresponds to the User Priority (0 - 7) and the value indicates the traffic class (0 - 7) to which the priority is mapped.
