How to Configure the Cisco Remote-PHY Solution

This section provides information on how to configure the Cisco Remote-PHY solution. These procedures provide only the initial and basic configurations for the Cisco Remote-PHY solution.


Note
The Cisco CMTS must be operational before beginning the following procedures to configure the Cisco Remote-PHY solution.

Configuring the Cisco uBR-MC3GX60V-RPHY Line Card

Configuring the Gigabit Ethernet Interface on the Cisco uBR-MC3GX60V-RPHY Line Card

The Cisco uBR-MC3GX60V-RPHY line card supports six (3 + 3) Gigabit Ethernet links and the links are arranged in three sets of redundant pairs. The links in the pair are modeled as an active-passive Gigabit Ethernet pair and traffic can be quickly switched from the working Gigabit Ethernet link to the standby Gigabit Ethernet link in the pair. The three active Gigabit Ethernet links are numbered as slotnumber/subslotnumber/0, 2, 4 and are mapped to the modular controllers slotnumber/subslotnumber/0, 1, 2 respectively.

The Cisco CMTS creates the following interfaces and controllers during the initialization of the Cisco uBR-MC3GX60V-RPHY line card:

  • Three Gigabit Ethernet interfaces
  • Three modular cable controllers
  • 24x3 modular cable interfaces

Each Gigabit Ethernet pair is assigned as follows:

Gigabit Ethernet pair

Assignment

Gigabit Ethernet {0, 1} - Gigabit Ethernet interface 0

Modular cable controller {0}; 0 to 23 channels; 0 to 31 bonding groups

Gigabit Ethernet {2, 3} - Gigabit Ethernet interface 2

Modular cable controller {1}; 24 to 47 channels; 32 to 63 bonding groups

Gigabit Ethernet {4, 5} - Gigabit Ethernet interface 4

Modular cable controller {2}; 48 to 71 channels; 64 to 95 bonding groups

Before You Begin
Restriction: Due to slow link loss detection, we do not recommend using the SFP-GE-T modules for primary interfaces.

    Configuring the Modular Cable Controller on the Cisco uBR-MC3GX60V-RPHY Line Card

    The downstream modular cable controller configuration defines the Layer 1 and Layer 2 parameters for the downstream RF channels, and the configuration parameters for the Gigabit Ethernet port. The modular cable controllers can be configured only using static DEPI.

    Before You Begin
    Restriction:

    When you are configuring the parameters for the downstream RF channel in a channel group, the value of a parameter (except the frequency) must be the same for all RF channels in the channel group. If you change the value of any parameter in a downstream RF channels, the value of that parameter changes in all other channels.

      Troubleshooting Tips

      Use the following troubleshooting tips if you did not get the expected results after performing the task.

      When you run the no rf-channel rf-channel number rf-shutdown command, the following error message is displayed: 

       %ERROR: Cannot unshut channel 0, please upgrade linecard license and retry

      This error message is displayed to indicate that there are insufficient licenses for the Cisco uBR-MC3GX60V-RPHY line card to unshut additional channels.

      Upgrade the license or shut down the active channel. To upgrade the license, see Software License Activation on Cisco CMTS Routers.

              • 200,000 (160,000 symbols/sec)—Not valid when using Unsolicited Grant Service (UGS) or UGS with Activity Detection (UGS-AD) service flows (such as PacketCable voice calls).

            • last-choice-width—Upstream channel width, in Hz. The valid values are the same as those for the first-choice-width parameter, but for proper operation, the last-choice-width should be equal to or less than the first-choice-width value. Use this parameter with supported cards to enable symbol rate management algorithms. The symbol rate automatically steps up from the first-choice-width value to the highest value until a stable channel is established.

            • A channel group can have a maximum of 16 downstream channels and all the downstream channels in a channel group must be associated with the same controller.
            • The Cisco CMCs, upstream and downstream channels must be mapped to the same Gigabit Ethernet Controller.
            • The upstream and downstream channels should be configured as a same fiber node.
