    UFM Interfaces

    Overview

    Interfaces on the UFM are defined by their names and types and are addressed in the following format: interface_name:location_id, as shown in Table 1:

    Note: The UFM6 is supported starting with release 4.1.

    Note: The QSFPP-4X10GD-LR (740-058730) transceiver is supported starting with release 4.2.

    UFM6 Interface and Protocol Restrictions

    Figure 1: UFM6 Client Ports

    UFM6 Client Ports

    Figure 1 shows the UFM6 client ports (port group 1). The client ports are divided into two subgroups: A for ports 1 through 5, and B for ports 6 through 10. Ports within a subgroup must be provisioned to use the same protocol rate; however, each subgroup can use a different protocol rate. For example, ports in subgroup A can be provisioned as QSFP+ (10-Gbps) ports, while ports in subgroup B can be provisioned as QSFP28 (100-Gbps) ports, or vice versa.

    Additionally, the QSFP28 transceiver can only be installed in the dual-mode client ports 1, 2, 6, and 7. Installing a QSFP28 transceiver in client ports 3, 4, 5, 8, 9, or 10 will cause an Inventory Unsupported (InventoryUnsupp) alarm to be raised against the transceiver.

    Table 2 lists the possible client port configurations for the supported transceivers.

    Multiplexed Interfaces

    An ODU4 interface on a UFM can be configured as a multiplexed (gmp-capable) interface that maps lower-order ODUs (ODU2 and ODU2e) into the ODU4 using the generic mapping procedure (GMP). The same ODU4 can contain a mix of ODU2 and ODU2e signals.

    Table 4 shows the multiplexing that is supported on the various UFMs:

    Table 4: UFM Multiplexed Interfaces

    Subinterface

    Description

    UFM

    Example identifiers

    ODU2 or ODU2e

    ODU4

    Ten lower-order ODU subinterfaces within an ODU4.

    Each ODU subinterface consists of eight 1.25 Gbps tributary slots.

    UFM3

    odu2:1/7/1/1.x or odu2e:1/7/1/1.x , where x is a value from 1 to 10.

    UFM4

    odu2:1/7/1/1.x , where x is a value from 1 to 10.

    Note: The UFM4 does not support ODU2e.

    UFM6

    odu2:1/5/2/1/2.1.2.x or odu2e:1/5/2/1/2.1.2.x , where x is a value from 1 to 10.

    The mapping of the subinterfaces to the containing ODU4 interface is specified by the optical data tributary group (odtg) and the tributary slot list (tributary-slot-list) attributes on the ODU4 interface. These attributes are automatically configured and cannot be changed. The mapping is shown in Table 5.

    Multiplexed Interfaces on UFM3 and UFM4

    The ODU2 subinterfaces are automatically created on UFM3 and UFM4 as follows:

    • When you configure an ODU4 interface for multiplexing, the system automatically creates 10 ODU2 subinterfaces .1 through .10. For example (truncated for clarity):
      bti7800(config)# do show interface table | include 1/7
      odu2:1/7/1/1.1      n/a                 no-multiplex     n/a                  
      odu2:1/7/1/1.2      n/a                 no-multiplex     n/a              
      odu2:1/7/1/1.3      n/a                 no-multiplex     n/a

      odu2:1/7/1/1.8      n/a                 no-multiplex     n/a            
      odu2:1/7/1/1.9      n/a                 no-multiplex     n/a                    
      odu2:1/7/1/1.10     n/a                 no-multiplex     n/a

      otu4:1/7/1/1        enabled      lowerLayerDown  192.100 THz  1560.61 nm  enabled 

    If you want ODU2e subinterfaces instead, delete the corresponding ODU2 subinterface and manually create the desired ODU2e subinterface. You can have a mix of ODU2 and ODU2e subinterfaces within the same ODU4. For information on changing between ODU2 and ODU2e subinterfaces, see Provisioning a Transport Interface.

    Multiplexed Interfaces on UFM6

    The ODU2e subinterfaces are automatically created on UFM6 as follows:

    • When you create an ODU4 line interface, the system automatically configures it for multiplexing and creates ten ODU2e subinterfaces .1 through .10. For example (truncated for clarity):
      bti7800(config)# do show interface table | include 1/5/2/1/2.1.2
      odu2e:1/5/2/1/2.1.2.1    n/a             no-multiplex     n/a          
      odu2e:1/5/2/1/2.1.2.2    n/a             no-multiplex     n/a         
      odu2e:1/5/2/1/2.1.2.3    n/a             no-multiplex     n/a

    If you want ODU2 subinterfaces instead, delete the corresponding ODU2e subinterface and manually create the desired ODU2 subinterface. You can have a mix of ODU2 and ODU2e subinterfaces within the same ODU4. For information on changing between ODU2 and ODU2e subinterfaces, see Provisioning a Transport Interface.

    Forward Error Correction (FEC) Types

    Forward error correction can be provisioned on OTU and optical channel interfaces. The following are the supported configurations:

    Table 6: FEC Types

    Interface

    Supported FEC Types

    OTU2 or OTU2e

    • No FEC (no-fec)
    • Generic FEC (g-fec)
    • G.975.1 i.4 Super FEC (s-fec-i4)
    • G.975.1 i.7 Super FEC (s-fec-i7)

    Note: The ports on the 12x SFP+ BIC are divided into three port groups (ports 1 to 4, ports 5 to 8, ports 9 to 12). Within each port group, you cannot configure one port for G.975.1 i.4 Super FEC and another port for G.975.1 i.7 Super FEC. The Super FEC settings are mutually exclusive within a port group.

    On a UFM6, all 10-Gbps client ports within the same QSFP+ transceiver have a similar restriction. You cannot configure one 10-Gbps port for G.975.1 i.4 Super FEC and another 10-Gbps port on the same transceiver for G.975.1 i.7 Super FEC. The Super FEC settings are mutually exclusive within a transceiver.

    OTU4 on 100G Coherent MSA XCVR

    • Soft-Decision FEC (soft-fec)

    OTU4 on 100G Coherent CFP

    • Soft-Decision FEC (soft-fec)

    OTU4 on all other CFPs

    • Swizzle FEC (swiz-fec)

    Optical channel on 400G Coherent MSA XCVR

    • Soft-Decision FEC with 25% overhead (sd-fec-25pc) for 16-QAM modulation
    • Soft-Decision FEC with 25% overhead (sd-fec-25pc) for QPSK modulation - Releases 4.2 and higher
    • Soft-Decision FEC (soft-fec) for QPSK modulation - Releases 4.2 and higher

    Note: This FEC is applied to the optical channel, which can include one or two OTU4 signals.
