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.

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.

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

             
            Step 4linecard-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 5rf-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 6end


            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.

            Configuring the Protect Line Card

            Before You Begin

            The slot mapping between the protect line card on the Cisco CMTS router and the protect switch cards on the Cisco UBR-RFSW-ADV is not required.

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

                 
                Step 4linecard-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 5member 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 6member 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 7end


                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

                Possible Cause    Power is down on the Cisco UBR-RFSW-ADV.
                Solution    Power on the Cisco UBR-RFSW-ADV.
                Possible Cause    The physical link between the Cisco CMTS router and the Cisco UBR-RFSW-ADV is down.
                Solution    Check if the RS-232 cable, which is a Cisco-style rolled cable with RJ-45 cables on both ends, is used between the Cisco CMTS router and the Cisco UBR-RFSW-ADV.

                Troubleshooting: Switch Card not Installed on the Cisco UBR-RFSW-ADV

                Problem    The state is Absent for some switch cards in the show hccp channel-switch state command output.

                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.
