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 and the QSFPP-4X10GE-LR (740-054050) and QSFP-100G-LR4-2 (740-074685) transceivers are supported starting with release 4.1.

Note

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

Note

The QSFPP-4X10GE-SR (740-054053), QSFP-100G-LR4-D (740-073859), and QSFP-100GBASE-SR4 (740-058734) transceivers are supported starting with release 4.3.

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 for the same rate group; however, ports in different subgroups can be provisioned for a different rate group. There are two protocol rate groups, as follows:

  • 10-Gbps, 40-Gbps

  • 100-Gbps

For example, ports in subgroup A can be provisioned as QSFP+ (10-Gbps) and QSFP+ 40GE (40-Gbps) ports, while ports in subgroup B can be provisioned as QSFP28 (100-Gbps) ports, or vice versa.

Additionally, the QSFP+ 40GE and QSFP28 transceivers can only be installed in specific client ports, as follows:

  • The QSFP+ 40 GE transceiver can only be installed in client ports 1, 2, 4, 5, 6, 7, 9, and 10. Installing a QSFP+ 40GE transceiver in client ports 3 or 8 will cause an Inventory Unsupported (InventoryUnsupp) alarm to be raised against the transceiver.

  • 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 UFM3, UFM4, or on the integrated transceiver on a UFM6 can be configured as a multiplexed (gmp-capable) interface that maps lower-order ODUs into the ODU4 using the generic mapping procedure (GMP). The same ODU4 can contain a mix of ODU2, ODU2e, and ODU3 signals (where supported).

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

Table 4: UFM Multiplexed Interfaces

Description

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.

ODU3

ODU4

Two lower-order ODU subinterfaces within an ODU4.

Each ODU subinterface consists of thirty-one 1.25 Gbps tributary slots.

UFM6

odu3:1/5/2/1/x.1.y.Z where x, y, Z are values from 1 to 2.

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 mappings for ODU2 and ODU2e interfaces into an ODU4 are shown in Table 5. Each ODU4 contains up to 10 ODU2 and ODU2e subinterfaces.

The mappings for ODU3 subinterfaces into an ODU4 on an optical channel on the UFM6 are shown in Table 6. Each ODU4 contains up to two ODU3 subinterfaces, but the mapping is different depending on whether the ODU3 is mapped to the first or to the second ODU4 in the optical channel. In the first ODU4, the ODU3 subinterfaces are mapped to the lower order tributary slots, leaving 16 unmapped higher order tributary slots for ODU2 and ODU2e mappings. In the second ODU4, the ODU3 subinterfaces are mapped to the higher order tributary slots, leaving 16 unmapped lower order tributary slots for ODU2 and ODU2e mappings.

If you are configuring a mix of ODU2, ODU2e, and ODU3 subinterfaces on an ODU4 on a UFM6, ensure that the subinterfaces do not use conflicting tributary slots. For example, if you configure ODU3 2.1, which uses tributary slots 17 to 47 on the second ODU4, you cannot also configure ODU2 or ODU2e subinterfaces 1.3 through 1.6 on the same ODU4 because those ODU2 or ODU2e subinterfaces use tributary slots 17 through 48.

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

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

If you want a different type of subinterface, delete the corresponding ODU2e subinterface and manually create the desired ODU subinterface. You can have a mix of ODU2, ODU2e, and ODU3 subinterfaces within the same ODU4. If you are creating an ODU3 subinterface, you will need to delete all the ODU2 and ODU2e subinterfaces that use the same tributary slots as the new ODU3 subinterface. See Table 5 and Table 6 for the tributary slots that the different ODU subinterfaces use.

For information on changing between ODU2, ODU2e, and ODU3 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 7: 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.
