Cisco uBR Advanced RF Switch Software Configuration Guide

Introduction

The Cisco uBR Advanced RF Switch (Cisco UBR-RFSW-ADV) provides N+1 line card redundancy switching for the Cisco uBR10012 universal broadband router. The Cisco UBR-RFSW-ADV is a rack-mount unit controlled by the Cisco uBR10012 router. The Cisco UBR-RFSW-ADV is located between the Cisco uBR10012 router and the cable plant. All the Cisco uBR10012 RF downstream (DS) and RF upstream (US) ports are connected to one side of the Cisco UBR-RFSW-ADV while the cable plant is connected to the other side.

All Cisco UBR-RFSW-ADV configurations are executed on the Cisco uBR10012 router.

  • At least two line cards must be configured with Hot-standby Connection-to-Connection Protocol (HCCP).
  • Two PREs must be installed in the Cisco uBR10012 router.
  • At least two line cards must be installed in the Cisco uBR10012 router.

Restrictions for Configuring the Cisco UBR-RFSW-ADV

The AUX port on the Cisco uBR10012 router cannot be used for the ISDL or modem.

Information About Configuring the Cisco UBR-RFSW-ADV

This section describes components, images and the IDs used in the communication between the Cisco uBR10012 router and Cisco UBR-RFSW-ADV.

AUX Port

The AUX port is an RS-232 serial port with an RJ-45 style connector provided on all PRE cards shipped with the Cisco uBR10012 router. This AUX port provides a readily-usable RS-232 interface that is used to connect to the Cisco UBR-RFSW-ADV. All commands are issued from the PRE to the Cisco UBR-RFSW-ADV using this AUX serial interface.

Golden Image

The image on the Cisco UBR-RFSW-ADV that is downloaded as part of the factory settings is called the Golden Image. This image is read-only and cannot be deleted or replaced using the CLI. In the case of an image (non-golden) download failure, you can boot the Cisco UBR-RFSW-ADV using the golden image. The letter g at the beginning of the image name indicates that it is a golden image. The two types of golden image are:

  • gcv—Golden Controller Version
  • gsv—Golden Switch Version

Alternate Image

The images that can be copied to or deleted from the Cisco UBR-RFSW-ADV are called the Alternate Image. The letter a at the beginning of the image name indicates that it is an alternate image.The two types of alternate image are:
  • acv—Alternate Controller Version
  • asv—Alternate Switch Version

To download an image (non-golden), see Downloading the Image from the Cisco CMTS to the Cisco UBR-RFSW-ADV.

Active Image

The image on the Cisco UBR-RFSW-ADV that is currently in use is called the Active Image. This image can be deleted or replaced only after another image is set as active.

Module ID

The Module ID is an unique index ID for the switch cards, which indicates the physical position in the Cisco UBR-RFSW-ADV for the switch card.

Figure 1. Module ID. The following figure shows the Module ID.

Slot ID

The switch cards in the Cisco UBR-RFSW-ADV are separated into eight slots. Each slot includes two upstream switch cards and one downstream switch card. Each slot is mapped to a line card on the Cisco uBR10012 router. The protect slot Id is zero.

Figure 2. Slot ID. The following figure shows the Slot ID.

Group ID

To control the upstream and downstream relays, the two upstream switch cards and one downstream switch card in a slot are divided into five groups. The 20 upstream are divided into four groups and the downstream belongs to the fifth group.

How to Configure the Cisco UBR-RFSW-ADV

This section describes how to configure the Cisco UBR-RFSW-ADV.

Enabling the Cisco UBR-RFSW-ADV

Before You Begin

In the default configuration, the Cisco UBR-RFSW-ADV is disabled. When the Cisco UBR-RFSW-ADV is enabled, the Cisco CMTS router polls the Cisco UBR-RFSW-ADV to check if it is connected and running.

Restriction:

You cannot use AUX port 1 on the Cisco uBR10012 router as a console port after the Cisco UBR-RFSW-ADV is enabled and it starts using AUX port 1 for communication.

SUMMARY STEPS

    1.    enable

    2.    configure terminal

    3.    redundancy

    4.    linecard-group id cable

    5.    rf-switch auxport enable

    6.    end


DETAILED STEPS
      Command or Action Purpose
    Step 1 enable


    Example:
    Router> enable
     

    Enables privileged EXEC mode.

    Enter your password if prompted.

     
    Step 2 configure terminal


    Example:
    Router# configure terminal
     

    Enters global configuration mode.

     
    Step 3 redundancy


    Example:
    Router(config)# redundancy
     

    Enables global N+1 redundancy and enters redundancy configuration mode.

     
    Step 4 linecard-group id cable


    Example:
    Router(config-red)# linecard-group 1 cable
     

    Assigns the HCCP group to all interfaces on the cable interface line card, or Cisco Broadband Processing Engine (BPE).

     
    Step 5 rf-switch auxport enable


    Example:
    Router(config-red-lc)# rf-switch auxport enable
     

    Enables the Cisco UBR-RFSW-ADV. In the default configuration, the Cisco UBR-RFSW-ADV is disabled.

    When the Cisco UBR-RFSW-ADV is enabled, the Cisco CMTS router starts polling the Cisco UBR-RFSW-ADV at a set interval to check its status.

     
    Step 6 end


    Example:
    Router# end
     

    Returns to privileged EXEC mode.

     
    What to Do Next

    Proceed to the Querying for the Image List on the Cisco UBR-RFSW-ADV.

    Troubleshooting Tips

    • The following commands can help troubleshoot the Cisco UBR-RFSW-ADV:
      • debug hccp rfswitch hello—Displays debug messages related to HELLO messages of the Cisco UBR-RFSW-ADV every three seconds.
      • debug hccp rfswitch—Displays debug messages related to a Cisco UBR-RFSW-ADV event, message, and failure.
    • If the Cisco CMTS router stops receiving a response from the Cisco UBR-RFSW-ADV, it implies that there is communication problem between the Cisco CMTS and the Cisco UBR-RFSW-ADV. Check the state using the show hccp channel-switch state command. The output should show the state as Normal. If the output shows the state as Absent, check the cable connection. If you still see communication problem contact TAC.

    Downloading the Image from the Cisco CMTS to the Cisco UBR-RFSW-ADV

    Before You Begin

    This procedure is used when an existing image on the Cisco UBR-RFSW-ADV is corrupt or out-of-date and needs to be replaced with an image available on the Cisco CMTS.

    Copying a switch image to Cisco UBR-RFSW-ADV starts downloading the image immediately and takes approximately three minutes to complete the download to each switch card and an hour to load the image on all the 24 switch cards.


    Note


    Wait until the image is downloaded fully and loaded on all the switch cards before proceeding further.


    Following describes the LED state indicating image download status:

    • Controller card LED flashes Green and the Switch card LED flashes Red—Image loading on the switch card is in progress.
    • Controller card LED flashes Green and the Switch card LED flash changes from Red to Blue to Green—Image loading is complete on the switch card.
    • Controller card LED illuminates Green and all the Switch card LEDs illuminate Green—Image loading is complete on all the switch cards.

    Prerequisites

    • The show hccp channel-switch state command output must show the current state as RFSW Ready and the switch card state as Normal.
    • Only a valid image for the Cisco UBR-RFSW-ADV must be downloaded from the Cisco CMTS.

    Note


    After data transfer, the Cisco UBR-RFSW-ADV validates the downloaded data to check if it is a valid image and reports the state to the Cisco CMTS. You can view the image using the show hccp channel-switch image command.


    Restrictions

    Only four images can reside on the Cisco UBR-RFSW-ADV; two images for the controller and two images for the switch card.

    SUMMARY STEPS

      1.    enable

      2.    cable rfswitch copy filename_cmts to-rfsw filename_rfsw

      3.    end


    DETAILED STEPS
        Command or Action Purpose
      Step 1 enable


      Example:
      Router> enable
       

      Enables privileged EXEC mode.

      Enter your password if prompted.

       
      Step 2 cable rfswitch copy filename_cmts to-rfsw filename_rfsw


      Example:
      Router# cable rfswitch copy disk0:acv2.11 to-rfsw acv2.11
       

      Copies an image from the Cisco CMTS router to the Cisco UBR-RFSW-ADV.

      • filename_cmts—Filename of the image that is copied to the Cisco UBR-RFSW-ADV from the Cisco CMTS router.
      • filename_rfsw—Filename for the image that is copied to the Cisco UBR-RFSW-ADV from the Cisco CMTS router.
       
      Step 3 end


      Example:
      Router# end
       

      Returns to privileged EXEC mode.

       
      What to Do Next

      Troubleshooting Tips

      1. If you get an error message that the file cannot be opened or read, check the filename on the Cisco CMTS router.
      2. If you get an error message that the image file cannot be downloaded to the Cisco UBR-RFSW-ADV, verify the connection state using the show hccp channel-switch state command. This command output must show the current state as RFSW Ready, the switch card state as Normal, and the AUXRFSW poll state as Succ. If the state is Fail, check the connection.
      3. If the downloaded controller image is not visible, try copying the image again to Cisco UBR-RFSW-ADV.
      4. If you get an error message that the file is an invalid image, contact the Cisco Technical Assistance Center (TAC).

      Uploading the Image from the Cisco UBR-RFSW-ADV to the Cisco CMTS Router

      Before You Begin

      This procedure is used when an existing image in the Cisco UBR-RFSW-ADV needs to be copied to the Cisco CMTS router for future use.

      Prerequisites

      • The Cisco UBR-RFSW-ADV must be connected to the Cisco CMTS router.
      • The show hccp channel-switch state command output must show the current state as RFSW Ready and the switch card state as Normal.

      Restrictions

      • Only the image name listed in the show hccp channel-switch image command output can be used for uploading.

        • filename_cmts—Filename for the image that is copied to the Cisco CMTS from the Cisco UBR-RFSW-ADV.
        • filename_rfsw—Filename of the image that is copied from the Cisco UBR-RFSW-ADV to the Cisco CMTS.
         
        Step 4 end


        Example:
        Router# end
         

        Returns to privileged EXEC mode.

         
        What to Do Next

        You may copy the uploaded image to a server using ftp/tftp/rcp for backup.

        Troubleshooting Tips
        • If you get an error message that the image file does not exist on the Cisco UBR-RFSW-ADV, verify if the image name is listed in the show hccp channel-switch image command output.
        • If you get an error message that the image file cannot be uploaded from the Cisco UBR-RFSW-ADV, verify the connection state using the show hccp channel-switch state command. The switch card state must be Normal. If the state is Absent, check the physical link between the PRE and the Cisco UBR-RFSW-ADV.
        • If you get an error message that the image file upload or write to the Cisco CMTS router failed, there is insufficient space on the Cisco CMTS router. Ensure that you have sufficient space to upload an image to the Cisco CMTS router.

                Router(config-red)# linecard-group 1 cable
                 

                Assigns the HCCP group to all interfaces on the cable interface line card, or Cisco Broadband Processing Engine (BPE).

                 
                Step 5 member subslot slot/subslot protect


                Example:
                Router(config-red-lc)# member subslot 5/0 protect
                 

                Configures all the interfaces on the specified line card to function as HCCP protect interfaces in the redundancy scheme.

                On the Cisco uBR10012 router, the valid values are:
                • slot—5 to 8
                • subslot—0 or 1
                 
                Step 6 member subslot slot/subslot working [rfsw-slot slot_id ]


                Example:
                Router(config-red-lc)# member subslot 6/1 working rfsw-slot 3
                 

                Configures all interfaces on the specified line card to function as HCCP working interfaces in the redundancy scheme.

                On the Cisco uBR10012 router, the valid values are:
                • slot—5 to 8
                • subslot—0 or 1

                Repeat this step for each working line card in the Cisco CMTS router.

                If you cable the cards in the Cisco UBR-RFSW-ADV and the Cisco CMTS router according to the default mapping, you need not use the rfsw-slot slot_id option to configure the slot mapping.

                To configure a non-default 7+1 mapping, use the rfsw-slot slot_id option. This enables you to cable any line card on the Cisco CMTS router to any Cisco UBR-RFSW-ADV slot (rfsw-slot). The valid value for the slot_id is from 1 to 8.

                 
                Step 7 end


                Example:
                Router# end
                 

                Returns to privileged EXEC mode.

                 

                Examples

                The following example shows how to configure the line card in slot/subslot 7/1 on the Cisco uBR10012 router as the working card and map it to slot 7 on the Cisco UBR-RFSW-ADV.

                Router> enable
                Router# configure terminal
                Router(config)# redundancy
                Router(config-red)# linecard-group 1 cable
                Router(config-red-lc)# rf-switch auxport enable
                Router(config-red-lc)# member subslot 5/0 protect
                Router(config-red-lc)# member subslot 7/1 working rfsw-slot 7
                Router(config-red-lc)# exit
                Router(config-red)# exit
                Router(config)# exit

                AUXRFSW poll state: Succ
                
                Possible Cause    The switch card is removed from the Cisco UBR-RFSW-ADV or is not working.
                Solution    Insert a new switch card to check its state.

                Troubleshooting: Cisco UBR-RFSW-ADV Does not Relay the Switch Card

                Problem    The cable modems go offline after a line card switchover.
                Possible Cause    The connection between the Cisco UBR-RFSW-ADV and the Cisco CMTS is broken.
                Solution    Check the link between the Cisco UBR-RFSW-ADV and the Cisco CMTS. The connection state must be Ready. If the state is not ready, reboot the Cisco UBR-RFSW-ADV using the cable rfswitch reboot command or upgrade the Cisco UBR-RFSW-ADV image.
