Prerequisites for Configuring the Cisco uBR10-MC5X20S Cable Interface Line Card

The Cisco uBR10-MC5X20S cable interface line card requires the following:

•The Cisco uBR10012 router must be running 12.2(11)CY or later to support the Cisco uBR10-MC5X20S cable interface line card.

•The Cisco uBR10012 router must be using one or two PRE1 processor modules to support the Cisco uBR10-MC5X20S cable interface line card. The PRE module is not supported.

•At least one Timing, Communication, and Control Plus (TCC+) card must be installed and operational in the Cisco uBR10012 router.

•Complete a basic configuration of the Cisco uBR10012 router; this includes, at a minimum, the following tasks:

–Configure a host name and password for the router.

–Configure the router to support Internet Protocol (IP) operations.

–Install and configure at least one WAN adapter to provide backbone connectivity.

–Install at least one Cisco uBR10-MC5X20S cable interface line card in an appropriate slot of the Cisco uBR10012 chassis. This is described in the Cisco uBR10-MC5x20S Cable Interface Line Card for the Cisco uBR10012 Series Router document.

–Bring up the router as described in the "Configuring the Cable Modem Termination System for the First Time" chapter in the Cisco uBR10012 Universal Broadband Router Software Configuration Guide.

•Determine a channel plan for your Cisco uBR10012 router and all of its cable interfaces.

•Verify that your headend site includes all necessary servers to support DOCSIS and Internet connectivity, including DHCP, ToD, and TFTP servers.

The Cisco uBR10012 router should be operational before beginning the following procedures to configure the Cisco uBR10-MC5X20S cable interface line card.

Restrictions for Configuring the Cisco uBR10-MC5X20S Cable Interface Line Card

In Cisco IOS Release 12.2(11)CY, the Cisco uBR10-MC5X20S cable interface line card has the following restrictions:

•The Cisco uBR10-MC5X20S cable interface line card requires a PRE1 module running Cisco IOS Release 12.2(11)BC1 or later. If using redundant processors, both processors must be PRE1 modules. You cannot use the Cisco uBR10-MC5X20S cable interface line card with a PRE module.

•When changing the symbol rate on the Cisco uBR10-MC5X20S cable interface line card, the
show controller cable upstream command may show US phy SNR_estimate - Unknown for a brief period of time. Wait a moment and reissue the command to obtain an accurate SNR value.

•The load-interval interface configuration command is not supported on the Cisco uBR-MC5X20S cable interface line card, although the command-line interface (CLI) accepts the command for these interfaces.

•The following software features are not supported for the Cisco uBR10-MC5X20S cable interface line card with Cisco IOS Release 12.2(11)CY:

–Cable Monitor.

–Point-to-Point Protocol over Ethernet (PPPoE).

–The Cisco uBR10-MC5X20S cable interface line card includes onboard spectrum management hardware. However, card support for advanced spectrum management features on the Cisco uBR10-MC5X20S cable interface line card will commence with future Cisco IOS releases. Future advanced spectrum management support will include all features currently available with the uBR-MC16S card.

•The configuration of the downstream and upstream ports is fixed into the five domains that are listed in Table 2.

•Each ASIC processor on the Cisco uBR10-MC5X20S interface line card supports two MAC domains. When using the Cisco uBR10012 router and Cisco uBR10-MC5X20S cable interface line card in N+1 Redundancy, MAC domains that share a common ASIC processor must be configured so that they share the same state: Active or Standby. Therefore, MAC domains fail over together.

Downstream MAC domain pairings would be downstream (DS) ports 0 and 1, ports 2 and 3, and port 4. For example, cable 5/0/0 and cable 5/0/1 share the same ASIC processor. Cable 5/0/2 and 5/0/3 share the second ASIC processor, and cable 5/0/4 is on the third ASIC processor, which is not shared.

Note Downstream port 4 is on its own MAC processor. If HCCP is not configured on an interface that shares a MAC processor with another configured interface, it will not failover.

Information About Configuring the Cisco uBR10-MC5X20S Cable Interface Line Card

The Cisco uBR10-MC5X20S cable interface line card supports downstream and upstream traffic over a Data-over-Cable Service Interface Specification (DOCSIS)-based cable modem network. The card supports 6-MHz National Television Systems Committee (NTSC) channel operation, using standard (STD), Harmonic Related Carrier (HRC), or Incremental Related Carrier (IRC) frequency plans. The card supports downstream channels in the 54 to 860 MHz range and an upstream range of 5 to 42 MHz.

Note Although you can use the Cisco uBR10-MC5X20S cable interface line card in 8-MHz international cable plants, the card operates only according to the DOCSIS specifications. This means that the card ignores the upper 2 MHz of available channel width, operates at a maximum bit rate of 5.36 mega-symbols per second, and limits upstream choices to the range below 42 MHz.

The Cisco uBR10-MC5X20S cable interface line card contains five downstream ports and twenty upstream ports. The downstream ports support 64-QAM and 256-QAM, and the upstream ports support QPSK and 16-QAM modulation.

Each downstream port includes an onboard integrated upconverter that generates an RF signal suitable for connection to a combiner and transmission on the coaxial cable network, without the need for any external upconverters. This can save both the money and rack space required by an external upconverter, as well as reduce the complexity of the equipment at the headend site.

The Cisco uBR10-MC5X20S cable interface line card supports all DOCSIS 1.1-specified Annex B radio frequency (RF) data rates, channel widths, and modulation schemes. Table 1 shows the supported DOCSIS data rates.

Note The Cisco IOS software automatically creates modulation profile 21 for the Cisco uBR10-MC5X20S card. This profile cannot be deleted.

The Cisco uBR10-MC5X20S cable interface line card is available withdense connectors. Each type of card contains a color-coded label that identifies the downstream and upstream ports. Figure 1 shows the front panels of each model.

Figure 1 Cisco uBR10-MC5x20S Cable Interface Line Card Front Panel View (Dense Connectors)

The five downstream ports are labelled DS0 RF through DS4 RF. The RF label indicates that the port is outputting an RF signal from the port's integrated upconverter. The 20 upstream ports are labelled US0 through US19.

In Cisco IOS Release 12.2(11)CY, each upstream port is statically associated with a particular downstream port. Table 2 shows the association between the Cisco uBR10-MC5X20S cable interface line card's physical port domains and the upstream and downstream ports associated with each domain. Table 2 also shows the interface label to use when referring to the port when using command-line interface (CLI) commands.

¹The X and Y in the CLI Cable Interface Label column refer to the physical card slot in which the card is installed. The value for X can range from 5 to 8, and the value for Y can be either 0 or 1.

For example, Table 2 shows that if the Cisco uBR10-MC5X20S cable interface line card is installed in slot 5/1, interface C5/1/3 contains domain #4, with downstream port DS3 RF and upstream ports US12, US13, US14, and US15. To configure upstream US14, you would therefore specify upstream U2 on cable interface 5/1/3 (interface c5/1/3).

Benefits of the Cisco uBR10-MC5x20S Cable Interface Line Card

Verifying the Upstream Port

To verify the current configuration of an upstream port, use the show controllers cable command for the desired upstream port.

show controllers cable {slot/port | slot/subslot/port} [downstream | upstream [port]]

Syntax Description

slot/port

Identifies the cable interface and downstream port on the Cisco uBR7246VXR router. slot can range from 3 to 6, and port can be 0 or 1, depending on the cable interface.

slot/subslot/port

Identifies the cable interface on the Cisco uBR10012 router. The following are the valid values:

•slot = 5 to 8

•subslot = 0 or 1

•port = 0 to 4 (depending on the cable interface)

downstream

(Optional) Displays downstream interface status.

upstream

(Optional) Displays upstream interface status.

port

(Optional) Specifies the desired upstream port. Valid values start with 0 for the first upstream port on the cable interface line card.

Examples

The following example shows a typical display that shows that the upstream is configured for a frequency of 6.0 Mhz, with a channel width of 1.6 MHz and 16-QAM modulation.

Note The upstream frequency displayed by the show controllers cable command output might not exactly match the frequency configured with the cable upstream frequency command, because Cisco cable interface line cards use frequencies in 16 KHz increments. For example, if you specify a frequency of 27 MHz, the upstream is programmed for a center frequency of 27.008 MHz, which is the next highest 16-KHz boundary.

Command Reference

This section describes the following new and changed commands that configure and monitor the Cisco uBR10-MC5X20S cable interface line card:

•cable downstream rf-power

•cable downstream rf-shutdown

•show hardware pxf cable

•show interface cable sid

Note Cable configuration commands are described in the Cisco Broadband Cable Command Reference Guide.

cable downstream rf-power

To set the RF power output level on an integrated upconverter on the Cisco uBR10012 universal broadband router or the Cisco uBR10-MC5X20S cable interface line card, use the cable downstream rf-power command in cable interface configuration mode. To reset the RF output power level to its default value, use the no form of this command.

cable downstream rf-power power-level
no cable downstream rf-power
Syntax Description

power-level

Desired RF output power level in dBmV. The valid range is 45 to 63 dBmV.

Note The official range for acceptable power levels in the DOCSIS specification is 50 to 61 dBmV. Cisco cable interfaces exceed the DOCSIS specification, but power levels outside the DOCSIS specifications should be used only in lab and test environments.

Defaults

50 dBmV for the Cisco uBR10012 universal broadband router

58 dBmV for the Cisco uBR10-MC5X20S cable interface line card on the Cisco uBR10012 router

Command Modes

Interface configuration (cable interface only)

Command History

Release

Modification

12.2(11)CY

Support was added for the Cisco uBR10-MC5X20S cable interface line card on the Cisco uBR10012 universal broadband router.

12.1(5)EC1

This command was introduced to provide support on the integrated upconverter on the Cisco uBR7100 series universal broadband router.

Examples

The following example shows the first integrated upconverter on a Cisco uBR10012 router being configured for an RF output power level of 55 dBmV:
router(config)# cable interface 5/1/0 
router(config-if)# cable downstream rf-power 55 
The following commands shows the first integrated upconverter being set to the default power level of 58 dBmV on the Cisco uBR10012 router:
router(config)# cable interface 5/1/0 
router(config-if)# no cable downstream rf-power 
Related Commands

Command

Description

cable downstream frequency

Configures the downstream center frequency on the integrated upconverter.

cable downstream rf-shutdown

Enables or disables the RF output from the integrated upconverter.

debug cable upconverter

Enables debugging of the internal upconverter operation.

show controllers cable

Displays status and configuration information for the cable interface.

cable downstream rf-shutdown

To disable the RF output from an integrated upconverter on the Cisco uBR10012 universal broadband router or the Cisco uBR10-MC5X20S cable interface line card, use the cable downstream rf-shutdown command in cable interface configuration mode. To enable the RF output on the integrated upconverter, use the no form of this command.

cable downstream rf-shutdown
no cable downstream rf-shutdown
Syntax Description

This command has no arguments or keywords.

Defaults

RF output is disabled.

Command Modes

Interface configuration mode (cable interface only)

Command History

Release

Modification

12.1(5)EC1

This command was introduced to provide support on the integrated upconverter on the Cisco uBR7100 series router.

12.2(11)CY

Support was added for the Cisco uBR10-MC5X20S cable interface line card on the Cisco uBR10012 router.

Usage Guidelines

By default, the integrated upconverter on the Cisco uBR10012 universal broadband router and the Cisco uBR10-MC5X20S cable interface line card is disabled, and the downstream port does not output any signal. The no form of this command enables the integrated upconverter, allowing it to output an RF signal through the downstream port.

However, before a valid DOCSIS downstream signal can be output, the following must also be done:

•A valid downstream RF frequency must be configured using the cable downstream frequency cable interface command.

•The cable interface must be enabled using the no shutdown command on the cable interface.

Note This command does not affect the IF output from the DS0 downstream port on the Cisco uBR10012 universal broadband router. The Cisco uBR10-MC5X20S cable interface line card does not provide IF output for its downstream ports.

Examples

The following example enables the second integrated upconverter on the Cisco uBR10012 router:
router(config)# cable interface 7/0/1 
router(config-if)# no cable downstream rf-shutdown 
The following commands must also be given before the DS0 RF port can transmit a valid RF signal:
router(config-if)# cable downstream frequency center-frequency 
router(config-if)# no shutdown 
router(config-if)# exit 
router(config)# 
Related Commands

Command

Description

cable downstream frequency

Defaults

No default behavior or values.

Command Modes

Privileged EXEC

Command History

Release

Modification

12.2(11)CY

This command was introduced for the Cisco uBR10012 router.

Usage Guidelines

The show hardware pxf cable command displays information about whether multicast echo and packet intercept are enabled on the cable interfaces. It can also be used to display the service flow ID (SFID) used for each multicast address that is being processed by the router.

Examples

show interface cable sid

To display the service identifier (SID) information for a CM, use the show interface cable sid command in privileged EXEC mode.

show interface cable {slot/port | slot/subslot/port} sid [association | counters | qos] [verbose]
Syntax Description

slot/port

(Cisco uBR7100 series router only) Identifies the cable interface and downstream port on the Cisco uBR7100 series router and is always 1/0.

slot/subslot/port

(Cisco uBR10012 router only) Identifies the cable interface and downstream port on the Cisco uBR10-MC5X20S cable interface line card on the Cisco uBR10012 router. The following are the valid values:

•slot = 5 to 8

•subslot = 0 or 1

•port = 0 to 4

association

Displays the virtual interfaces (VRF) or Interface Descriptor Blocks (IDBs).

connectivity

Displays the values of the per-SID connectivity statistics. This option appears only in DOCSIS 1.0 and 1.0+ releases.

counters

Displays the values of the per-SID usage counters. Same as the keyword stats that appeared in Cisco IOS Release 11.3(5)NA and earlier releases.

qos

Displays the QoS characteristics received by each SID.

verbose

Displays detailed information.

Command Modes

Privileged EXEC

Command History

Release

Modification

11.3 XA

This command was introduced.

11.3(6)NA

The keyword stats was changed to counters.

12.0(4)XI

The primary SID information was added.

12.0(5)T

The command output was modified to identify secondary SIDs.

12.0(7)XR and 12.0(7)T

The verbose keyword was added.

12.1(4)CX, 12.2(1)XF, and 12.2(4)BC1

The qos keyword was added to display information on the QoS values received by the SID from the MAC scheduler.

Also, the connectivity option was moved to the show cable modem command.

12.1(11)EC, 12.2(8)BC1

The association keyword was added.

12.2(11)CY

Three codeword fields were added to the verbose counters display to support the Cisco uBR10-MC5X20S cable interface line card. These fields always display zero for the other cable interface line cards.

Usage Guidelines

Data transport over the radio frequency (RF) link uses the registered SID address rather than the Ethernet address. This allows multiple hosts to access the network via a single CM.

The verbose keyword can be used with any of the other options or by itself.

Examples

The following sample output from the show interface cable sid command shows the various forms of the command. Some examples cite the Cisco uBR7200 series platform. The displays on other Cisco CMTS platforms are similar.

Online State
Offline State

"Online" means that the modem owning this SID is processing traffic. "Offline" means that the modem owning this SID is not processing traffic.

Admin Status

"Disable" means that the SID has been turned off. "Enable" is the normal state.

QoS

Quality of service.

Create time

When the SID was created, number of seconds since the system booted.

Input octets (Inoctets)

Number of octets received by using this SID.

Input packets (Inpackets)

Number of packets received by using this SID.

Output octets (Outoctets)

Number of octets sent from this SID.

Output packets (Outpackets)

Number of packets sent from this SID.

IP address

IP address of the modem owning this SID.

MAC address

MAC address of the modem owning this SID.

BW requests received

Number of bandwidth requests received by this SID.

Grants issued

Number of bandwidth requests granted by this SID.

Rate exceeded BW request drops
