Monitoring Wideband Line Cards

The following section provides commands used to monitor Cisco Wideband line cards:

•show diag for Wideband SIPs

•show diag for the Cisco uBR-MC3GX60V Line Card

•show hw-module bay oir

•show diag for Wideband SPA

•show controllers modular-cable for Cisco uBR-MC3GX60V Line Card

•show controllers modular-cable <controller> sfp for Cisco uBR-MC3GX60V Line Card

•show controllers modular-cable for Wideband SPA

•show controllers cable

The show diag command is useful for monitoring Cisco Wideband SPA, Wideband SIP, and wideband line cards. It shows basic information such as how long the card or wideband SPA (or SIP) has been up, its voltage status, and the software image version it is running.

In addition, the show controllers modular-cable and show controllers jacket commands displays extensive line card information including hardware device register values. The show controllers commands are intended for use only by Cisco Systems technical support personnel.

show diag for Wideband SIPs

To verify that the Wideband SIP is powered on, use the show diag command. If show diag displays any output, the Wideband SIP is powered on. The show diag command provides a variety of information on the Wideband SIP. In the following example, the hardware type of the Wideband SIP is 2jacket-1 card.

show controllers modular-cable <controller> sfp for Cisco uBR-MC3GX60V Line Card

To monitor the SFPs plugged into the Cisco uBR-MC3GX60V line card, use the show controller modular-cable <controller> sfp command. It displays the SFP presence, manufacturer, and most importantly, link status. The Cisco uBR-MC3GX60V line card has six SFP ports, ports 0 to 5.

The example below shows that an SFP is plugged into Port 4, but not 5 and the SFP present has an UP link state.

show controllers cable

To display information about RF channels and their attributes that are added to the cable MAC domain, use the show controllers cable slot/subslot/port downstream command. This applies to all MAC domain card types, Cisco uBR-MC5X20, Cisco UBR-MC20X20V, Cisco uBR-MC8X8V, and Cisco uBR-MC3GX60V line cards.

The following configuration shows the modular-cable interface channels of a SPA in bay 1/1/0 added to the MAC domain c8/0/0:
Router# show run interface c8/0/0 | inc Modular-Cable
 downstream Modular-Cable 1/1/0 rf-channel 1 upstream 1
 downstream Modular-Cable 1/1/0 rf-channel 4 upstream 0
 downstream Modular-Cable 1/1/0 rf-channel 7 upstream 0
The MAC domain configuration shown in the preceding configuration provides the following SPA RF downstream channel information in the show controllers cable slot/subslot/port downstream command output (in this example, the output is for cable 8/0/0 where a uBR-MC5X20 line card is in subslot 8/0):

Upstream Controller Monitoring

To display information about the number of MAP and UCD MAC management messages sent on a DS channel (that has been added to primary-capable channels that are part of a MAC domain), use the show controllers cable slot/subslot/port upstream command.

The following configuration shows the modular-cable interface channels added to the MAC domain c8/0/0:
Router# show run interface c8/0/0 | inc Modular-Cable
 downstream Modular-Cable 1/1/0 rf-channel 1 upstream 1
 downstream Modular-Cable 1/1/0 rf-channel 4 upstream 0
 downstream Modular-Cable 1/1/0 rf-channel 7 upstream 0
The MAC domain configuration shown in the preceding configuration provides the following information for US channels associated with SPA DS channels that are added to the MAC domain in the show controllers cable slot/subslot/port upstream command output (in this example, the output is for cable8/0/0):

Monitoring Wideband Channels

The following commands are useful for monitoring wideband channels:

•show interface wideband-cable

•show hw-module bay and show controller

show interface wideband-cable

To display information about a wideband-cable interface (wideband channel), use the show interface wideband-cable command. Wideband channels are similar to cable interfaces and information about them is also displayed with the show ip interfaces and show interfaces commands.

The following example displays the show interface wideband-cable command output for wideband channel 0 on the Wideband SPA in slot/subslot/bay 1/0/0.
Router# show interface wideband-cable 1/0/0:0
Wideband-Cable1/0/0:0 is up, line protocol is up

     0 output errors, 0 collisions, 0 interface resets
     0 output buffer failures, 0 output buffers swapped out
Hardware Status and Line Protocol Status for a Wideband-Channel and Modular-Cable Interface

When a wideband-channel cable interface is specified in the show interface wideband-cable command or another Cisco IOS command that displays hardware status (initializing, down, up, or administratively down) and line protocol status (down or up) for a cable interface, the following applies:

•In the case of a Wideband SIP and SPA, the hardware status for a wideband cable interface will be up if the Wideband SPA is installed in the Wideband SIP, and both are powered on, and config mode has been entered for the interface.

•In the case of a Cisco uBR-MC3GX60V or Cisco UBR-MC20X20V line card, the hardware status for a wideband-cable interface will be up if the line card is installed, powered on, and config mode has been entered for the interface at least once.

•The line protocol for a wideband-channel cable interface will be up if the wideband channel is associated with at least one RF channel by configuration and the following parameters have been set for the RF channel:

–Frequency

–IP-address

–MAC-address

–DEPI-remote-id

If the line protocol for a wideband cable interface is up, all wideband cable configuration information needed to successfully send data is present. However, additional configuration information may be needed to complete the Wideband SPA configuration process. For more information on Wideband SPA configuration procedures, see the Cisco uBR10012 Universal Broadband Router SIP and SPA Software Configuration guide.

For more information about the Cisco UBR-MC20X20V line card based wideband-cable interface, see Configuring the Cisco UBR-MC20X20V Cable Interface Line Card guide.

For more information about the Cisco uBR-MC3GX60V line card based wideband-cable interface, see Configuring the Cisco uBR-MC3GX60V Cable Interface Line Card guide.

When a modular-cable interface is specified in the show interface modular-cable command or another Cisco IOS command that displays hardware status and line protocol status for a cable interface, such as the show ip interfaces brief command, the following applies:

•In the case of a Wideband SIP and SPA, the hardware status for a modular-cable interface will be up if the Wideband SPA is installed in the Wideband SIP and both are powered on.

•In the case of a Cisco UBR-MC20X20V line card, the hardware status for a integrated-cable interface will be up if the line card is installed, powered on, and config mode has been entered for the interface at least once.

•In the case of a Cisco uBR-MC3GX60V line card, the hardware status for an modular-channel cable interface will be up if the line card is installed, powered on, and config mode has been entered for the interface at least once.

•The line protocol for a modular-cable interface will be up if the following settings have been applied to the RF channel:

•The upstream channels from the MAC domain cable interface line card must be associated with the modular-cable interface or integrated-cable downstream channels in a given cable MAC domain.

•The total bandwidth allocated for the interface must be greater than or equal to 1 percent.

•In the case of a Wideband SPA, the modular host must be configured on the modular-cable controller for the corresponding SPA. The modular-host is the line card responsible for managing per-modem BPI, PHS, and DSID indexes.

•In the case of an M-CMTS modular-cable interface, a DEPI remote ID must be configured for this channel. The UDP port number must not be configured in this case.

•RF channel frequency parameter must be set for the RF channel.

show hw-module bay and show controller

To display additional information about a wideband channel of a Wideband SPA, use the show hw-module bay commands. Use the show controller modular-cable commands for a Cisco uBR-MC3GX60V line card, and the show controller integrated-cable commands for a Cisco UBR-MC20X20V line card. You can then specify one of the following keywords indicating the particular type of information you want to display:

•association—Displays wideband-to-narrowband MAC domain association information. The association of a wideband channel to a MAC domain is made when a primary downstream channel for the fiber node is configured with the downstream command and the wideband interface channels are also in the fiber node.

•config—Displays wideband channel configuration information.

•counters wideband-channel—Displays wideband channel statistics.

•mapping—Displays the mapping of RF channels to wideband channels.

To display wideband-to-narrowband channel association (the MAC domains using the wideband channel) information, use the show hw-module bay command with the association and wideband-channel keywords. If you specify a wideband channel number after the wideband-channel keyword, the output is shown only for that channel:
Router# show hw-module bay 1/0/0 association wideband-channel 0
WB                      BG   Bundle  NB          NB chan  Reserved  Total

Wideband-Cable1/0/0:0   24   1       Cable5/0/1  120      0         0 
In the preceding example, the following information is displayed for each wideband channel:

Monitoring Narrowband RF Channels

The following commands are useful for monitoring narrowband RF channels:

•show interface modular-cable and show interface integrated-cable

•show hw-module bay

•show controller modular-cable and show controller integrated-cable

show interface modular-cable and show interface integrated-cable

To display information about narrowband interfaces, use the show interface modular-cable or show interface integrated-cable command. Narrowband interfaces information is also displayed with the show ip interface and show interfaces command.

The following is sample output of the show interface modular-cable command:

show hw-module bay

To display information about RF channels on a Wideband SPA, use the show hw-module bay command with the rf-channel keyword. You also have to specify one of the following keywords indicating the particular type of information you want to display:

•config—Displays RF channel configuration information.

•counters—Displays RF channel statistics.

•mapping—Displays the mapping of RF channels to wideband channels.

To display configuration information for an RF channel, use the show hw-module bay command with the config and rf-channel keywords. If you specify an RF channel number after the rf-channel keyword, output is for that channel only. For example, the following output is for RF channel 0 on the Wideband SPA located in slot/subslot/bay 1/0/0.
Router# show hw-module bay 1/0/0 config rf-channel 0 
Freq       Mod     Anx  IP Address     MAC Address     UDP Port/    If

In the preceding output, these fields provide information on the edge QAM device that is associated with the RF channel:

•IP address—IP address of the edge QAM device.

•MAC address—MAC address of the next-hop or edge QAM device.

•DEPI ID or UDP port—DEPI ID or UDP port number for the edge QAM device that will be used for this RF channel.

To display MPEG packets transmitted for an RF channel, use the show hw-module bay command with the counters and rf-channel keywords.

show controller modular-cable and show controller integrated-cable

For the Cisco uBR-MC3GX60V and Cisco UBR-MC20X20V line card, the config, counters, and the mapping commands shown in the preceding configuration are displayed with the show controller command.

The config command displays all aspects of the configuration for the controller and its channels.

To display configuration information for an RF channel, use the show controller modular-cable rf-channel command.

The following example shows how to display the configuration information for the rf-channel 0 on the modular interface 5/0/0:
router# show controllers modular-Cable 5/0/0 rf-channel 0
Ctrl Chan Frequency  Mod Annex IP Address      MAC Address    DEPI Remote ID

To display the per RF channel packet counts, bandwidth usage, SYNC, MAP, and non-SYNC and MAP packet counts use the counters rf command. This command is used to monitor channel saturation and the distribution of bandwidth in the cable plant.

For the Cisco Wideband SPA and Cisco UBR-MC20X20V line card, the channel bandwidth usage is computed based on the MPEG frames, each of which is 188 bytes.

For the Cisco uBR-MC3GX60V line card, the channel bandwidth is computed based on the DMPT (DOCSIS MPEG Transport) frames, which are a composite of MPEG frames.

The following example displays the output of the show controller modular cable counter rf command for the Cisco uBR-MC3GX60V line card:
router# show controller modular-Cable 5/0/1 counter rf

show cable mac-domain downstream-service-group

To display MAC domain downstream service group information for a primary downstream channel, use the show cable mac-domain downstream-service-group command. The service-group is determined from the channels placed in the fiber nodes; therefore, if fiber nodes are being reconfigured, use this command to check if the downstream service-group is updated.

The following example displays show cable mac-domain downstream-service-group output for the primary downstream channel on the cable interface at slot/subslot/port 5/0/0:
Router# show cable mac-domain cable5/0/0 downstream-service-group 
Primary  MD-DS-SG         RF                                                            
IF       Id        SPA    Chan                                                          
C5/0/0   1         1/0/0  0 - 1
In the preceding example, the MD-DS-SG with ID 1 is used for RF channels 0 and 1 on the Wideband SPA located in slot/subslot/bay 1/0/0.

The following example displays the show cable mac-domain downstream-service-group output of two 8-channel downstream service groups for a Cisco uBR-MC3GX60V MAC domain.
router# show cable mac-domain ca6/0/0 downstream-service-group 
Cable    MD-DS-SG              RF
IF       Id        Resource    Chan     Primary Chan

                               20-23    
         2         6/0/0       00-03    0 1 2 3 
                               20-22    
show cable mac-domain cgd-associations

To display a summary of the channel grouping domain (CGD) associations for a MAC domain, use the show cable mac-domain <interface> cgd-associations command.

The following is sample output of the show cable mac-domain cgd-associations command for the cable interface at slot 5, subslot 0, and port 0:
Router# show cable mac-domain c5/0/0 cgd-associations
CGD Host  SPA   DS Channels             Upstreams (All)   Active Remote DS
Ca5/0/0         Local                   1            Y
          1/0/0 0-1                     0
The preceding example shows the following information for the cable MAC domain host, which is the cable interface at slot 5, subslot 0, and port 0:

•The SPA downstream channels 0 and 1 from the SPA slot 1, subslot 0, and bay 0 have been added to this MAC domain.

Upstream 1 is associated with the Cisco uBR10-MC5X20 downstream channel. If the All column in the command output indicates Y, then this indicates that all upstream channels are associated with the Cisco uBR10-MC5x20 line card downstream channels (in this case, one or more SPA downstream channels are configured using the upstream cable connector command). If all upstream channels are not configured, then this column will not display.

Troubleshooting Power Up Issues

This section describes troubleshooting techniques for a Wideband SIP or Wideband SPA. It includes the following sections:

•Performing Basic Power Troubleshooting on a Wideband SIP and Wideband SPA

•Performing Basic Power Troubleshooting on the Cisco uBR-MC3GX60V Line Card

•Verifying the Up State of an Active Gigabit Ethernet Port of a Wideband SPA

•Verifying That a Wideband SPA Is Correctly Configured for SPA-to-EQAM Communications

•Verifying That a Wideband SPA Is Able to Communicate with the Edge QAM Device

Performing Basic Power Troubleshooting on a Wideband SIP and Wideband SPA

To perform basic troubleshooting on a Wideband SIP and Wideband SPA, complete the following steps:
Action

More Information or Example
Step 1

Use the show diag command to check that a Wideband SIP is powered on.
Router# show diag 1/0 
Slot/Subslot 1/0:                                                               
        2jacket-1 card, 0 ports                                                 
        Card is full slot size                                                  
        Card is analyzed                                                        
        Card detected 0:3:16 ago                                              
        Card uptime 0 days, 0 hours, 3 minutes, 17 seconds                    
...
If show diag displays output, the Wideband SIP is powered on. If show diag displays no output, the Wideband SIP is not powered on.
Step 2

Check that the Wideband SIP FAIL LED is not on.
The FAIL LED is turned on by default and turned off by 
software after basic board functionality has been verified. 
If the SIP FAIL LED remains on, the SIP has failed to 
initialize or has encountered an error. 
Step 3

Use the show hw-module bay oir command to check that a Wideband SPA is powered on.
Router# show hw-module bay 1/0/0 oir
Module        Model                Operational Status
------------- -------------------- ------------------------
bay 1/0/0     SPA-24XDS-SFP        ok
•If the Operational Status is "ok," the Wideband SPA is powered on and operational.

•If the Operational Status is "admin down," the Wideband SPA is not powered on.
Step 4

Check that the Wideband SPA STATUS LED is lit green.

•If the STATUS LED is green, the SPA is ready and operational.

•If the STATUS LED is amber, SPA power is on and good, and the SPA is being configured.

•If the STATUS LED is off, SPA power is off.

Step 5

If cables are connected to one or both of the SPA Gigabit Ethernet port SFP modules and the links for these should be up, check that the Wideband SPA A/L (Active Loopback) LEDs are lit green.

•If the A/L LED is green, the port is enabled and the link is up.

•If the A/L LED is amber, the port is enabled and the link is down.

•If the A/L LED is off, the port is not enabled.
Performing Basic Power Troubleshooting on the Cisco uBR-MC3GX60V Line Card

To perform the basic power troubleshooting on a Cisco uBR-MC3GX60V line card, execute the show diag command on the subslot, the card is plugged into. If no output is displayed, then the card is not powered on.

Check for the following, in case the card is not powered on:

•Card has been inserted correctly and is screwed in.

•There are no extraneous subslot shutdown commands in the configuration preventing the card from booting up. To perform this, execute the show running | include hw-mod.*shutdown command.

If the show diag command does not display any output and the card is not powered off by configuration, physically examine the card faceplate and check the Fail LED status. If it is on, then the line card is not booting correctly.

Note When using a Cisco uBR-MC3GX60V line card, the empty slots in the Cisco uBR10012 router chassis must be filled with blank filler cards to maximize the air flow and keep the line cards functioning within proper thermal boundaries.

Troubleshooting DOCSIS Timing and Control Card

This section describes troubleshooting techniques for the DOCSIS Timing and Control Card (DTCC). It includes the following sections:

•Verifying Active DTCC and Status

•Verifying DTI Counters

•Verifying DTI Clock Synchronization

Verifying Active DTCC and Status

For the M-CMTS network architecture, DTI-based timing must be enabled using the cable clock dti command in global config mode. If DTI timing does not functioning correctly, cable modems do not reach the init() state.

To determine the active DTCC and its current status, use the show cable clock command:
Router# show cable clock
Number of TCC Cards in the Chassis: 1
Active TCC Card is in slot: 1 subslot: 1,(DTCC Eightbells card) Clock reference used by 
the active card is DTI
Active TCC card in slot 1/1
TCC Card 1/1 DTI status:
------------------------------------------- 
   Active Client port	: 2
   Active Client status	: normal 
   Active Client Server status	: freerun 
   Active Client frame error rate : < 2% 
   Active Client CRC error count : 0xFC 
   Standby Client Signal detected : no
No card in slot 2/1
If the Cisco uBR10012 chassis has two DTCCs, this command can be used to determine which DTCC is active. If the DTI client has established communications with a DTI server, the show cable clock command displays the current status. If the active DTCC is connected to a DTI server that is delivering a DOCSIS time stamp and frequency, the Active Client status displays as normal. However, if the connection to the DTI server is lost, the Active Client status displays as freerun (see previous example).

Note When a DTI server is first powered on, it may stay in the warmup state until its internal oscillator has stabilized. This may take more than 15 minutes.

Verifying DTI Counters

To display the DTI counters for the clock card, use the show cable clock dti counters slot/subslot command.

The following example displays the show cable clock dti counters slot/subslot command output for slot 1 and subslot 1:
Router> show cable clock dti counters 1/1
TCC Card 1/1 DTI counters:
------------------------------------------- Client Normal time	: 0xFFFF Client Holdover 
time	: 0x0000
Client Phase Correction	: 0x0000
Client Freq Correction	: 0xFBD7
Client EFC Correction	: 0xF7AD Client transition count t3	: 0x00
Client transition count t4	: 0x01
Client transition count t6	: 0x00
Client transition count t7	: 0x00
Verifying DTI Clock Synchronization

Three main components in the M-CMTS system need to have a synchronized DOCSIS clock:

1. CMTS DTCC card

2. CMTS cable line card, and

3. EQAM

To verify the CMTS timing at the DTCC and MAC domain card, enter the following three commands in rapid succession:

•show cable clock dti client 1/1 | i Timestamp

•show controller Cable5/0/0 | i Timestamp

•On the CISCO RFGW10 EQAM, execute the show cable clock | i timestamp command.

Note The Harmonic NSG EQAM has a GUI screen that can display the clock.

The timestamps shown will not match exactly due to the 10 MHz rate of the clock, but the three timestamps should be close. If the timestamps are not close, verify the following:

•DTI wiring from the DTI server to the CMTS DTCC card

•DTI wiring from the DTI server to the EQAM

•Proper configuration of the three devices. The CMTS must be configured with the cable clock dti command.

The following example verifies the CMTS timing at the DTCC and MAC domain card:
Router> show cable clock dti client 1/1 | i stamp
    Client timestamp               : 0x38683C64
Router> show contr ca5/0/0 | i stamp             
  Timestamp is from TCC card
 Master Clock Timestamp = 0x3B0E1F89
RFGW-10# show cable clock | i stamp
Client timestamp               : 0x3C4F02FA
Troubleshooting EQAM Connectivity Issues of the M-CMTS

This section describes troubleshooting techniques for EQAM connectivity to the M-CMTS. It includes the following sections:

•Verifying the Up State of an Active Gigabit Ethernet Port of a Wideband SPA

•Verifying the Up State of an Active Gigabit Ethernet Port of a Cisco uBR-MC3GX60V Line Card

•Verifying Layer 3 Connectivity to the EQAM

Verifying the Up State of an Active Gigabit Ethernet Port of a Wideband SPA

The Gigabit Ethernet ports on a Wideband SPA are not considered standard user-configurable interfaces; However, they appear in the configuration (since Cisco IOS Release 12.2[33]SCC) because the DEPI protocol transmits and receives control packets by using this interface. The Wideband SPA is a controller with one active and one redundant Gigabit Ethernet port. The show controller modular-cable command displays information about the SPA, its Gigabit Ethernet active port, installed small form-factor pluggable (SFP) modules, and so on.

The following example provides sample show controller modular-cable output for the Wideband SPA located in slot 1, subslot 0, bay 0 of a Cisco uBR10012 router.
Router#  show controller modular-cable 1/0/0 brief 
SPA 0 is present
status LED: [green]
Host 12V is enabled and is okay.
Power has been enabled to the SPA.
SPA reports power enabled and okay.
SPA reports it is okay and is NOT held in reset.
Gigabit Ethernet Port Selected : Port 1
Receive Interface              : In Reset
Receive Interface              : Disabled
Transmit Interface             : Out of Reset
Transmit Interface             : Enabled
Primary Receive Clock          : Disabled
Backup Receive Clock           : Disabled
SFP [Port 0] : 1000BASE-SX Present 
 Tx Enabled , LOS Detected , TxFault Not Detected
 Link Status [Port 0] : DOWN 
SFP [Port 1] : 1000BASE-T Present 
 Tx Enabled , LOS Not Detected , TxFault Not Detected
 Link Status [Port 1] : UP 
... 
In the preceding output, notice the following:

•The Gigabit Ethernet Port Selected field indicates the active Gigabit Ethernet port.

•For the active Gigabit Ethernet port, the SFP [Port 1] field indicates the type of SFP module that is present.

•For the active Gigabit Ethernet port, the Link Status [Port 1] field indicates whether the link is up.

The Cisco Wideband SPA transmits data in a unidirectional manner only and does not receive data from devices connected to its active Gigabit Ethernet port.

If the link for the active Gigabit Ethernet port is not up, check the following:

•The SFP module is correctly installed and matches the SFP module in the connected device.

•The cables to the Wideband SPA ports are correctly connected to a powered-on device.

•The cables to the Wideband SPA ports are not bent or damaged.

•A hardware failure has not occurred. For information, see the "Performing Basic Power Troubleshooting on a Wideband SIP and Wideband SPA" section.

Use the show controller modular-cable command with the sfp keyword to get more detailed information on the SFP modules installed in the Wideband SPA Gigabit Ethernet ports.

Verifying the Up State of an Active Gigabit Ethernet Port of a Cisco uBR-MC3GX60V Line Card

The Cisco uBR-MC3GX60V line card can have up to six SFPs for its three controllers. To check the presence and link status of the SFPs, use the show controller modular-cable <slot/subslot/controller> sfp command.

If the SFP is not present, the show controller modular-cable <slot/subslot/controller> sfp command output displays:
Router# show controller modular-cable 6/0/0 sfp
SFP in Port1 is NOT PRESENT
If the SFP is present, confirm if the physical port status is Up in the show controller modular-cable <slot/subslot/controller> sfp command output:
Router# show controller modular-cable 6/0/0 sfp
SFP in Port0 is Present.  Init status Success 
        TX_DISABLE not set, LOS not detected, TX_FAULT not detected
 LOS detection supported: no
 Tx Fault detection supported: no
SFP Interrupt Counts:
        LOS:0, PRES:0, TX_FAULT:0
Link Status of the MV88E1146C DS Gige Phy Port: UP <<<——— Physical port status is up
Verifying Layer 3 Connectivity to the EQAM

As of Cisco IOS Release 12.2(33)SCC, DEPI control plane functionality requiring bidirectional communication between the CMTS and the EQAM has been supported. This communication requires a Gigabit Ethernet interface visible to the IOS and hence visible with the show ip interfaces brief command.

Note Only a very small fraction of the Gigabit Ethernet interface bandwidth is actually used by the DEPI protocol.

Both the Wideband SPA and the Cisco uBR-MC3GX60V line card have one Gigabit Ethernet interface per controller, therefore a Wideband SPA has one such interface and a Cisco uBR-MC3GX60V line card has three interfaces.

With an IP address is configured on the interface in a subnet, that includes the EQAM, the IP address of the EQAM is pingable. This provides a basic verification method of the bidirectional communication between the CMTS and the EQAM.

The following example shows the ping command output of an EQAM from the CMTS through the Gigabit Ethernet port of controller 0 of a Cisco uBR-MC3GX60V line card:
!
interface GigabitEthernet5/0/0
 ip address 10.31.136.215 255.255.255.0

Success rate is 100 percent (5/5), round-trip min/avg/max = 1/9/12 ms
Troubleshooting Primary-Capable Channel DOCSIS Signalling

This section describes troubleshooting techniques for the Primary-capable Channel DOCSIS Signalling. It includes the following sections:

•Verifying MAP, UCD, SYNCs for Primary-Capable Channels

•Verifying MDD Packet Transmit for DOCSIS 3.0 Operations

Verifying MAP, UCD, SYNCs for Primary-Capable Channels

All primary-capable channels of a MAC domain transmit MAPs, UCDs, SYNCs packets downstream. In the case of DOCSIS 3.0 deployments, MDD is also transmitted.

For the MAC domain to transmit the packets, the associated modular-cable or integrated-cable interface must have UP status as shown in the show ip interfaces command output. If the interface is not up, verify the following:

1. The interface has been configured with the cable rf-bandwidth-percent command to have at least 1 percent of bandwidth.

2. The interface has been unshut.

3. The controller parameters are configured. This includes frequency, annex, modulation type, and interleaver.

4. The CGD configuration has been done in the MAC domain interface using the downstream Modular-cable or downstream integrated-cable command. Multiple configuration lines for primary channels may be used.

5. For modular-cable interfaces, the Gigabit Ethernet SFP is in the UP state (see Verifying the Up State of an Active Gigabit Ethernet Port of a Cisco uBR-MC3GX60V Line Card)

When the modular-cable or integrated cable interface is up, verify that at least one upstream in the MAC domain is up with the show interface <mac domain interface> upstream command.

After the upstream is UP, verify if the MAPs, SYNCs, and UCDs are being transmitted. This can be done at 2 layers:

1. At the MAC domain layer, use the show controller command. Execute the show controllers <MAC domain> upstream <upst ream number> | begin Map Counts command and verify the output to determine if the Map Counts counter is incrementing.

2. At the hardware layer, use the show controller <modular-cable | integrated-cable> <slot/subslot/controller> counters rf command. Verify the output to determine if the MAP Pkts counter is incrementing. Verify if the SYNC Pkts counter is incrementing. Without any Layer 3 traffic, the Mbps rate for one upstream channel is approximately 0.9 to 1.0 Mbps. The Mbps rate for four upstreams is approximately 1.7 to 1.9 Mbps.

Verifying MDD Packet Transmit for DOCSIS 3.0 Operations

To support downstream and upstream bonding, the fiber node or fiber nodes in use by a MAC domain must be properly configured. The fiber node is used to calculate the correct downstream service groups and upstream service group IDs placed in the MDD packets. The fiber node configuration includes specifying the downstream channels and the upstream connector in use. The downstream channels must not have frequency or downstream channel ID conflicts.

The following example shows an invalid fiber node:
router# show running | begin fiber.*224    
cable fiber-node 224
  downstream Modular-Cable 5/0/2 rf-channel 8-11 20-23
!
router# show cable fiber 224
---------------------------------------------------------------------------------
Fiber-Node 224 
  Channel(s)   :  downstream Modular-Cable    5/0/2:   8-11 20-23
  Channel ID(s):  57, 58, 59, 60, 69, 70, 71, 72
    FN Config Status: Configured (status flags = 0x41)
    MDD Status: Invalid
                No US Connector Configured
Use the show controller <MAC domain> | begin MDD command to check the number of MDD packets being transmitted. The following example shows that no MDD packets are transmitted:
router# show contr ca5/0/12 | beg MDD
  MDDs           Primary          Non-Primary     
  ----------------------------------------------
  ----------------------------------------------
Use the show cable mac-domain <MAC domain> downstream-service-group command to examine the downstream service groups for the MAC domain. The following example shows that there is no service group configured since the fiber node is invalid.
router# show cable mac-domain ca5/0/12 downstream-service-group 
Cable    MD-DS-SG              RF
IF       Id        Resource    Chan     Primary Chan
C5/0/12
Completing the fiber node configuration with an upstream connector resolves the service group, which in turn allows the MAC domain to transmit MDD packets. The following example shows the above debug commands after a connector is configured in the fiber node causing it to be valid which in turn causes the service groups to be calculated and MDD packets to be transmitted and counted in the controller.
router# conf t           
Enter configuration commands, one per line.  End with CNTL/Z.
router(config)#cable fiber 224
router(config-fiber-node)# upstream cable 5/0 connector 12
router(config-fiber-node)# end
Fiber node 224 is valid.
router# show run | begin fiber.*224

Troubleshooting Wideband SIP and Wideband SPAs

Verifying That a Wideband SPA Is Correctly Configured for SPA-to-EQAM Communications

If a Wideband SPA is unable to communicate with an edge QAM device, check that the RF channels configured with the rf-channel command match the values required by the edge QAM device. You can use the show hw-module bay command to see the values that have been configured for an RF channel:
Router# show hw-module bay 1/0/0 config rf-channel 0 verbose 
SPA                                 : Wideband-Cable 1/0/0

Check that the following values are correct and match what is configured on the edge QAM device:

•Frequency—Center frequency used for this RF channel.

•IP address of next hop—IP address of the edge QAM device for this RF channel.

•MAC address—MAC address of the next-hop or edge QAM device for this RF channel.

•DEPI Remote ID—DEPI ID of the RF channel on the EQAM. The DEPI ID is seen with the non-verbose form of this command.

•UDP port—UDP port number for the QAM output port for this RF channel.

If any of the above values do not match what is present on the edge QAM device, the Wideband SPA will not be able to successfully communicate with that device.

On the Cisco uBR10012 router, RF channels are configured with the rf-channel command. The values on the edge QAM are device-specific and are typically configured when setting up the edge QAM device.

Verifying That a Wideband SPA Is Able to Communicate with the Edge QAM Device

To verify that a Wideband SPA that has been correctly configured for wideband operations is communicating with the edge QAM device, use the show hw-module bay command with the counters and rf-channel keywords. In the following example, only RF channels 0 to 3 on the Wideband SPA are transmitting MPEG packets.
Router# show hw-module bay 1/0/0 counters rf-channel 
SPA      RF channel   MPEG packets tx        Sync Tx          MP Pkts Tx

Troubleshooting Wideband Channels

This section describes troubleshooting techniques for wideband channels. It includes the following sections:

•Verifying That a Wideband Channel Is Up and Is Transmitting Packets

•Verifying That a Wideband Channel Is Configured Correctly

For information about configuring wideband channels, see the Cisco uBR10012 Universal Broadband Router SIP and SPA Software Configuration Guide.

Verifying That a Wideband Channel Is Up and Is Transmitting Packets

To verify that a wideband channel is up and transmitting packets, use the show interface wideband-cable command and examine the first line of the output and the packets output field:
Router# show interface wideband-cable 1/0/0:1 
Wideband-Cable1/0/0:1 is up, line protocol is up 
  Hardware is Wideband CMTS Cable interface, address is 0012.001a.8897 (bia 
0012.001a.8897)

     0 output errors, 0 collisions, 0 interface resets
     0 output buffer failures, 0 output buffers swapped out
For information on what criteria are used to determine whether a wideband channel and its associated line protocol are up, see the "show interface wideband-cable" section.

Verifying That a Wideband Channel Is Configured Correctly

To verify whether a wideband channel is configured correctly, use the show hw-module bay command with the wideband-channel keyword and the association, config, or mapping keywords. The following examples show the output for the association keyword:
Router# show hw-module bay 1/0/0 association wideband-channel 0
WB                      BG   Bundle  NB          NB chan  Reserved  Avail
channel                 ID   num     channel     ID       CIR       CIR
Wideband-Cable1/0/0:0   24   123     Cable5/0/1  120      0         0 
In the preceding output, the Bundle num field indicates the virtual bundle interface to which the wideband channel belongs. For a description of each field in the preceding output, see the "show hw-module bay and show controller" section.

The wideband channel and the primary downstream channel (NB channel) must be members of the same virtual bundle interface. The CMTS running configuration file shows the virtual bundle (cable bundle) for the primary downstream channel (Cable5/0/1):
interface Cable5/0/1
 no ip address
 load-interval 30
 no cable packet-cache
 cable bundle 123
 cable downstream channel-id 120
... 
The downstream modular-cable rf-channel command specifies the RF channels that are available for wideband channels on a fiber node. If a wideband channel attempts to use an RF channel that has not been made available for use on the fiber node, a misconfiguration error occurs. In this case, the show hw-module bay command displays the following error message:
Router# show hw-module bay 1/0/0 association wideband-channel 
WB                      BG   Bundle  NB          NB chan  Reserved  Avail
channel                 ID   num     channel     ID       CIR       CIR
Wideband-Cable1/0/0:0   RF channel mismatch with Fiber Node 1
The following example shows the show hw-module bay command output for the config keyword:
Router# show hw-module bay 1/0/0 config wideband-channel 
WB                      BG    Bundle  WB Host       Primary 
channel                 ID    num     Slot/Subslot  BG

Wideband-Cable1/0/0:4   28    123     5/0           Yes 
Wideband-Cable1/0/0:5   29    123     5/0           Yes 
Wideband-Cable1/0/0:6   30    123     5/0           Yes 
Wideband-Cable1/0/0:7   31    123     5/0           Yes 
Wideband-Cable1/0/0:8   32    0       5/0           Yes 
Wideband-Cable1/0/0:9   33    0       5/0           Yes 
Wideband-Cable1/0/0:10  34    0       5/0           Yes 
Wideband-Cable1/0/0:11  35    0       5/0           Yes 
In the preceding output, each wideband channel that is used should be configured as a member of a virtual bundle interface. Channels 8 through 11 are not members of a virtual bundle interface.

The following example shows the show hw-module bay command output for the mapping keyword:
Router# show hw-module bay 1/0/0 mapping wideband-channel 
SPA      WB       RF         BW %
         channel  channel

                  23         100 
A channel-bonded wideband channel is associated with at least two RF channels depending on the wideband channel configuration. The cable rf-channel command associates an RF channel with a wideband channel. The bandwidth percent (BW %) of each RF channel used for the wideband channel is 100 percent by default, but is configurable with the cable rf-channel command.

Troubleshooting Wideband Cable Modems

This section describes troubleshooting techniques for wideband cable modems. It includes the following sections:

•Pinging a Wideband Cable Modem

•Verifying That a Wideband-Capable Cable Modem Is Registered as a Wideband Modem

•Examining Wideband-Capable Modems That are Partial Online

•Verifying Other Information for Wideband Cable Modems

Pinging a Wideband Cable Modem

To determine whether a wideband cable modem or any DOCSIS cable CPE device is reachable from the CMTS at the DOCSIS MAC layer, use the ping docsis command with either a MAC address or IP address:
Router# ping docsis 1.11.0.5         
Queueing 5 MAC-layer station maintenance intervals, timeout is 25 msec:
!!!!!
Success rate is 100 percent (5/5)
The ping docsis command uses 1/64—the bandwidth of IP ping—and works with cable modems that have not yet acquired an IP address. This allows you to ping cable modems that are unable to complete registration, that have internal bugs, or that are unresponsive due to a crash.

The ping docsis command with the verbose keyword includes a real-time view and plot of requested power adjustments, frequency, timing offset adjustments, and a measure of optimal headend reception power.
Router# ping docsis 1.11.0.5 verbose 
Queueing 5 MAC-layer station maintenance intervals, timeout is 25 msec:

Reply from 0014.bfbe.3e3c: 50 ms, tadj=-1, padj=0, fadj=39
Success rate is 100 percent (5/5)
For more information on the ping docsis command, see the Cisco Broadband Cable Command Reference Guide.

Verifying That a Wideband-Capable Cable Modem Is Registered as a Wideband Modem

To verify that a wideband-capable cable modem is registered as a wideband modem, use the show cable modem command. In the following example, the MAC address of the wideband cable modem is specified:
Router# show cable modem 0014.bfbe.3e70 
MAC Address    IP Address      I/F       MAC          Prim RxPwr  Timing Num BPI
                                         State        Sid  (dBmv) Offset CPE Enb
0014.bfbe.3e70 1.11.0.3        C5/0/1/U0 w-online(pt) 1     0.00  1231    0   Y 
If a wideband-capable cable modem is registered as a wideband modem, the MAC State field will have one of the w-online values (wideband-online), such as w-online(pt) in the preceding example. For descriptions of the complete set of MAC state values, see the show cable modem command in the Cisco Broadband Cable Command Reference Guide.

A wideband-capable modem may also register as a DOCSIS 2.0 modem (for example, if a wideband channel is not available). In this case, the MAC State field displayed by the show cable modem command will not have one of the w-online values.

To determine the set of wideband-capable cable modems that have registered as wideband modems on the CMTS, use the show cable modem wideband command:
Router# show cable modem wideband 
MAC Address    IP Address      I/F       MAC            Prim  BG  DSID  MD-DS-SG
                                         State          Sid   ID
0014.bfbe.3e70 1.11.0.3        C5/0/1/U0 w-online(pt)   1     24  24    N/A
0014.bfbe.3e3c 1.11.0.4        C5/0/1/U0 w-online(pt)   2     24  24    N/A
0016.92fb.5742 1.11.0.6        C5/0/1/U0 w-online(pt)   3     24  256   1     
0016.92fb.580e 1.11.0.7        C5/0/1/U0 w-online(pt)   4     24  264   1     
0014.bfbe.3eaa 1.11.0.2        C6/0/1/U0 w-online(pt)   7     36  36    N/A
0016.92fb.57f8 1.11.0.5        C6/0/1/U0 w-online(pt)   8     36  298   1     
0016.92fb.57f4 1.11.0.8        C6/0/1/U0 w-online(pt)   9     36  306   1 
To determine the set of wideband-capable cable modems that have registered as DOCSIS 2.0 modems on the CMTS, use the show cable modem wideband command with the registered-traditional-docsis keyword.

Examining Wideband-Capable Modems That are Partial Online

A fault in one or more channels in the CMTS or cable plant may result in a wideband modem being partial online. DOCSIS 3.0 includes signaling based on the CM-STATUS message that enables modems to inform the CMTS about downstream failures. The CMTS will track and react upon these messages. The CMTS may disable an RF channel in a wideband channel, causing the modems to go into partial online mode, p-online. The show cable modem partial command can used to view all modems in the p-online state.

To determine the cause of the partial online status, use the show cable modem <address> wideband rcs-status command for a modem in p-online mode. Failures reported by the modem will be counted categorically. For example:
Router # show cable modem 50.3.81.80 wideband rcs-status 
CM  : 0025.2e2d.74b8
RF  : 5/0/2 8
  Status                   : UP
  FEC/QAM Failure          : 0         
  Dup FEC/QAM Failure      : 0         
  FEC/QAM Recovery         : 0         
  Dup FEC/QAM Recovery     : 0         
  MDD Failure              : 0         
  Dup MDD Failure          : 0         
  MDD Recovery             : 0         
  Dup MDD Recovery         : 4         
  Flaps                    : 0         
  Flap Duration            : 00:00
RF  : 5/0/2 10
  Status                   : UP
  FEC/QAM Failure          : 0         
  Dup FEC/QAM Failure      : 0         
  FEC/QAM Recovery         : 0         
  Dup FEC/QAM Recovery     : 0         
  MDD Failure              : 0         
  Dup MDD Failure          : 0         
  MDD Recovery             : 0         
  Dup MDD Recovery         : 0         
  Flaps                    : 0         
  Flap Duration            : 00:00
The type of error reported can then be used to further troubleshoot the problem on the CMTS, the EQAM or the cable plant.
