    Provisioning a Transport Interface

    Use this procedure to provision a transport interface on a UFM.

    Prerequisites

    • The corresponding transceiver is provisioned.
    1. Enter configuration mode.
      bti7800# config
      bti7800(config)#
    2. Add the interface.

      The following example adds an OTU4 interface. See UFM Interfaces for information on setting the interface type.

      bti7800(config)# interface otu4:1/7/1/1
      Value for 'type' [ethernetCsmacd,otnOdu,otnOtu,sonet]: otnOtu 
      bti7800(config-interface-otu4:1/7/1/1)# 

      Note: This automatically creates a corresponding odu4:1/7/1/1 interface.

    3. Specify the frequency of the interface. This is required for interfaces with tunable transceivers.

      For example:

      bti7800(config-interface-otu4:1/7/1/1)# frequency 192.1
    4. Specify the type of FEC to use. The FEC type can only be changed when the interface is disabled.

      For example:

      bti7800(config-interface-otu4:1/7/1/1)# disabled
      bti7800(config-interface-otu4:1/7/1/1)# fec-type soft-fec 
      bti7800(config-interface-otu4:1/7/1/1)# commit 
      Commit complete. 
      bti7800(config-interface-otu4:1/7/1/1)# enabled 
      bti7800(config-interface-otu4:1/7/1/1)# commit 
      Commit complete. 

      See Forward error correction (FEC) types for information on supported values for the fec-type.

    5. Specify whether the corresponding ODU interface is a multiplexed (muxponding) or non-multiplexed (transponding) interface.

      Note: Muxponding is only supported when multiplexing onto ODU4 interfaces.

      1. To configure a non-multiplexed interface:
        bti7800(config-interface-odu4:1/7/1/1)# multiplex-mode no-multiplex
        bti7800(config-interface-odu4:1/7/1/1)# commit 
        Commit complete.
      2. To configure a multiplexed interface:
        bti7800(config-interface-odu4:1/7/1/1)# multiplex-mode gmp-capable
        bti7800(config-interface-odu4:1/7/1/1)# commit 
        Commit complete. 

        After you configure a multiplexed ODU4 interface and commit the changes, the lower-order subinterfaces are automatically created. Depending on the UFM, the system creates either ODU2 or ODU2e subinterfaces.

        Here is an example of the lower-order ODU2 subinterfaces within an ODU4 (truncated for clarity):

        bti7800(config)# do show interface table | include odu2:1/7/1/1
        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  
        odu2:1/7/1/1.4      n/a                 no-multiplex     n/a 
        odu2:1/7/1/1.5      n/a                 no-multiplex     n/a 
        odu2:1/7/1/1.6      n/a                 no-multiplex     n/a  
        odu2:1/7/1/1.7      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 

        Here is an example of the lower-order ODU2e subinterfaces within an ODU4 (truncated for clarity):

        bti7800(config)# do show interface table | include odu2e: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     
        odu2e:1/5/2/1/2.1.2.4    n/a             no-multiplex     n/a 
        odu2e:1/5/2/1/2.1.2.5    n/a             no-multiplex     n/a 
        odu2e:1/5/2/1/2.1.2.6    n/a             no-multiplex     n/a          
        odu2e:1/5/2/1/2.1.2.7    n/a             no-multiplex     n/a        
        odu2e:1/5/2/1/2.1.2.8    n/a             no-multiplex     n/a  
        odu2e:1/5/2/1/2.1.2.9    n/a             no-multiplex     n/a   
        odu2e:1/5/2/1/2.1.2.10   n/a             no-multiplex     n/a  
      3. To change a subinterface between an ODU2 and an ODU2e:

        In some situations, you might want to change an ODU2 subinterface to an ODU2e subinterface and vice-versa. To do this, delete the subinterface you want to replace and create the desired subinterface.

        For example, the following deletes an ODU2e subinterface and creates a new ODU2 subinterface at that same location.

        bti7800(config)# no interface odu2e:1/5/2/1/2.1.2.5
        bti7800(config)# interface odu2:1/5/2/1/2.1.2.5
        Value for 'type' [ethernetCsmacd,opticalChannel,otnOdu,otnOtu,...]: otnOdu
        bti7800(config-interface-odu2:1/5/2/1/2.1.2.5)# commit
        Commit complete.

        Note: You must delete and create the subinterface before committing. If you commit in between the deletion and creation, you will get an error.
