    expected-section-trace string

    The section level trace message expected in the received SONET/SDH signal. This applies to SONET/SDH interfaces only.

    0 to 62 characters

    An empty string, which means no section trace expected

    expected-trace string

    The trace message expected in the received OTU signal

    0 to 64 characters

    An empty string, which means no trace message expected

    fec-type type

    The forward error correction (FEC) type used in the OTU link

    Note: This attribute is not supported on an OTU4 interface on the UFM6 400G Coherent MSA XCVR. You cannot configure the FEC on an individual OTU4 on the UFM6. You can only configure the FEC for the optical channel interface only.

    The following are the allowed types:

    • no-fec
    • g-fec
    • s-fec-i4
    • s-fec-i7
    • sd-fec-25pc
    • soft-fec
    • swiz-fec

    Note: Not all FEC types are supported for all protocols and transceivers. See Forward Error Correction (FEC) Types for more details.

    400G Coherent MSA XCVR: sd-fec-25pc

    100G Coherent CFP: soft-fec

    fpsd {true | false}

    Enables or disables fault propagation shutdown (FPSD) for ethernetCsmacd interfaces.

    If a fault is detected upstream (in the receive from backplane direction) and this parameter is set to true, the system turns off the laser to propagate the fault signal. If this parameter is set to false, the system transmits a Local Fault indication instead. In either case, the signal in the link receive direction is unaffected.

    true

    false

    true

    frequency frequency

    The frequency of the optical signal in THz.

    For a single-channel transceiver, this indicates the frequency at which the transceiver operates. For a multi-channel transceiver, this indicates the frequency of the first channel (channel with the highest frequency number).

    Note: A frequency or wavelength value is required to create an interface on tunable transceivers. You do not need to configure both a frequency and a wavelength. If you configure both a frequency and a wavelength, the values must be consistent.

    Note: For the 400G Coherent MSA XCVR, this attribute is configured on the optical channel interface only.

    Refer to DWDM Wavelength Plan for valid DWDM frequency and wavelength grid values.

    The specified frequency must match a valid grid frequency.

    None

    grid {f50GHz|f100GHz|f200GHz}

    The frequency spacing of channels on the WDM composite signal

    f50GHz: 50 GHz grid spacing

    f100GHz: 100 GHz grid spacing

    f200GHz: 200 GHz grid spacing

    None

    lldp-snoop {disable|enable}

    Configures LLDP snooping

    Note: Supported only on Ethernet interfaces.

    disable

    enable

    loopback-mode {facility|noLoopback|terminal}

    mapping {asynchronous|bit-synchronous}

    Specifies the type of mapping of the SONET/SDH signal onto an ODU payload

    asynchronous

    synchronous

    asynchronous

    multiplex-mode {no-multiplex|gmp-capable}

    This is used to configure the OPU payload of the ODU for multiplexing lower order OPUs.

    When set to gmp-capable, the ODU multiplex structure supports multiplexing of ODTUk.ts or ODTUk.ts and ODTUjk (payload type 0x21).

    no-multiplex

    gmp-capable

    no-multiplex

    odtg

    This is the list of optical data tributary groups (ODTG) that are configured on the ODU if the payload type is set to gmp-capable. Each ODTG contains a lower order ODU.

      

    prbs-mode {egress|ingress|no-prbs}

    Configures PRBS signal generation on the interface.

    Refer to prbs-mode for usage.

    Note: This parameter is not supported on UFM6 interfaces.

    sd-deg-thr percent

    The threshold used to evaluate whether a 1-second interval is considered a degraded interval for OTU interfaces.

    The threshold is the percentage of errored blocks in a 1-second interval. If the percentage of errored blocks detected in a 1-second interval exceeds this threshold, the interval is considered degraded.

    0.0001 to 100.0

    0.1

    sd-degm num_intervals

    The number of consecutive degraded intervals required to raise a signal degrade fault for OTU interfaces.

    When the value is set to 0, signal degrade monitoring is disabled.

    0, 2 to 10

    8

    sd-thr neg_exponent

    The threshold used to evaluate whether a SONET/SDH signal degrade fault has occurred.

    If the bit error rate exceeds the specified threshold, a signal degrade fault is raised.

    The value entered is a negative exponent. For example, a value of 4 is interpreted as 10-4.

    When the value is set to 0, signal degrade monitoring is disabled.

    0, 4 to 12

    6

    signaling-mode {legacy|standard}

    The signaling mode for interworking with legacy equipment on Ethernet interfaces.

    See the BTI7800 Series Software Configuration Guide for details.

    legacy

    standard

    standard

    tx-power power

    The desired output signal power in dBm (applicable to interfaces on the 100G Coherent MSA XCVR, the 400G Coherent MSA XCVR, and the 100G Coherent CFP only)

    Note: For the 400G Coherent MSA XCVR, this attribute is configured on the optical channel interface only.

    Varies depending on the transceiver

    Varies depending on the transceiver

    tx-trace string

    The trace message inserted into the transmitted OTU signal

    0 to 64 characters

    UFM6: A combination of the management IP address and the ifIndex.

    Other UFMs: A combination of the management IP address and the interface identifier.

    wavelength wavelength

    Wavelength of the optical signal (nm). This attribute is set automatically when you set the frequency.

    For a single-channel transceiver, this indicates the wavelength at which the transceiver operates. For a multi-channel transceiver, this indicates the wavelength of the first channel (channel with the lowest wavelength number).

    Note: A frequency or wavelength value is required to create an interface on tunable transceivers. You do not need to configure both a frequency and a wavelength. If you configure both a frequency and a wavelength, the values must be consistent.

    Note: For the 400G Coherent MSA XCVR, this attribute applies to the optical channel interface only.

    Refer to DWDM Wavelength Plan for valid DWDM frequency and wavelength grid values.

    The specified wavelength does not need to match a valid grid wavelength. The BTI7800 converts the specified wavelength to a frequency rounded to the nearest 50 GHz. The resulting frequency is then checked against valid grid values.

    If the frequency matches a valid grid value, the CLI updates the frequency attribute with the resulting frequency when you commit the change. If the frequency does not match a valid grid value (that is, outside the range), the CLI returns an error when you try to commit the change.

    None
