Information About the Cisco uBR-MC3GX60V Cable Interface Line Card
With 72 downstream and 60 upstream channels, the Cisco uBR-MC3GX60V line card supports 9 service groups (SGs) for 8-channel downstream bonding, and 18 SGs for 4-channel downstream bonding. This line card can provide up to 72 SGs of 8 downstreams for a Cisco uBR10012 router. A larger number of SGs may be supported when downstream channels are shared between MAC domains.
The Cisco uBR-MC3GX60V cable line card has 4 connector inputs and 12 PHY receivers. The upstream channel-to-physical connector assignment is flexible enough to provide any combination of 1 to 12 channels per connector from the 4-connector bundle. This means four separate connectors could provide three US channels each, or two of the four connectors could provide six US channels each, and so on.
Note
The Cisco uBR10012 chassis with the Cisco uBR-MC3GX60V line card offers high density downstream solutions for IP Video over DOCSIS (VDOC) and cable high speed data (HSD) applications.

Configuring the GigE Interface for Downstream on the Cisco uBR-MC3GX60V Cable Interface Line Card
The Cisco uBR-MC3GX60V line card supports six (3 + 3) GigE links that connect to the Cisco RF Gateway. The links are arranged in three sets of redundant pairs.
The links in the pair are modeled as an active-passive GigE pair and traffic can be quickly switched from the working GigE link to the standby GigE link in the pair.
The three active GigE links are numbered as slot/subslot/0, 2, 4 and are mapped to the modular controllers slot/subslot/0, 1, 2 respectively. You are not required to configure the passive GigE links.
During the initialization of the Cisco uBR-MC3GX60V line card, the following are created:

Configuring Global HCCP N+1 Line Card Redundancy on the Cisco uBR10012 Router
Note
N+1 redundancy refers to (N) cable interface line cards, referred to as working line cards that are protected by an additional line card (+1), referred to as the protect line card.
Note
N+1 redundancy provides synchronization between the HCCP working interface configurations and those configurations that are inherited during the switchover to the HCCP protect interfaces. This makes the configuration of the HCCP working and protect interfaces easier and the switchover times faster.
For more information, see the N+1 Redundancy for the Cisco Cable Modem Termination System feature guide.

The Cisco CMTS supports an N+1 DEPI redundancy to protect against the Cisco uBR-MC3GX60V cable line card failures and switchovers. In the redundancy mode, the protect line card establishes a backup DEPI session. The primary DEPI control connection and session is established on the GigE ports of the working line card. The two DEPI sessions are paired through the common transport stream identifier (TSID).
Note
In an N+1 line card redundancy, the protect line card initiates a DEPI control session to the RF Gateway channels during bootup. When the protect line card detects a line card failure, it enables all sessions of the failed line card. If there are multiple line cards with sessions to the same RF Gateway, the protect line card has a control connection and multiple corresponding secondary data sessions within it. The Cisco CMTS associates the primary and secondary sessions using the TSID, which has matching values for the corresponding primary and secondary sessions.
For more information, see the M-CMTS DEPI Control Plane feature guide at Cisco.com.

Run the show depi, show depi session endpoints (for the DEPI session status), and show depi tunnel endpoints (for the DEPI tunnel status) commands to view the DEPI session details.
Each of the four QAMs on an RF Gateway port must have the same RF power level and a contiguous frequency range. A configuration that does not meet these conditions is rejected by the RF Gateway.
On the Cisco CMTS side, this rejection results in intermittent connectivity problems or flapping of the DEPI sessions. The mismatch in RF power level or frequency mismatch are displayed in the Reason field in the show depi session configured output
Router# show depi session configuredSession Name State Reason TimeModular-Cable8/0/0:0 IDLE QC RF Power mismatch Sep 19 18:49:42To resolve this issue, align the RF power for the QAMs to be the same value or align the frequency for the QAMs so they have a contiguous range, or do both.

Configuring Manual DEPI on the Cisco uBR-MC3GX60V Cable Interface Line Card
The manual DEPI configuration also supports N+1 DEPI redundancy and port-level redundancy on the Cisco uBR-MC3GX60V line card. In manual DEPI configuration, you do not have to configure the protect tunnel. The working card configuration is automatically applied to the protect card through IPC messages.
The DEPI connection between the M-CMTS router and the EQAM is static in manual DEPI configuration. Data sessions are not established dynamically in manual DEPI configuration.
For more information, see the M-CMTS DEPI Control Plane feature guide at Cisco.com.

The following MAC domain commands are useful for troubleshooting bonding operations:
•
•
•
•
•
To troubleshoot software license issues, use the following commands:
•
•
For the M-CMTS network architecture, DOCSIS Timing Interface (DTI) based timing must be enabled with the following global configuration command:
•
If DTI timing does not function correctly, modems are not be seen even in an init() state.
To determine the active DOCSIS Timing and Control Card (DTCC) and its current status, run the following command:
•
Router# show cable clockNumber of TCC Cards in the Chassis: 1Active TCC Card is in slot: 1 subslot: 1,(DTCC Eightbells card) Clock reference used by the active card is DTIActive TCC card in slot 1/1TCC Card 1/1 DTI status:------------------------------------------- Active Client port : 2Active Client status : normal Active Client Server status : freerun Active Client frame error rate : < 2% Active Client CRC error count : 0xFC Standby Client Signal detected : noSome other commands that you can use to troubleshoot the Cisco uBR-MC3GX60 line card:
•
To verify that the Cisco uBR-MC3GX60 line card is powered on, use the show diag command. If the output of the show diag command displays any output, the Cisco uBR-MC3GX60 line card is powered on.
If the Cisco uBR-MC3GX60 line card is powered on, verify that:
–
–
If show diag command does not display any output and the card is powered on by configuration, physically examine the line card face plate and check the Fail LED status. If the LED is on, then the line card is not booting correctly.
Note
•
The Cisco uBR-MC3GX60 line card can have up to six Small Form-Factor Pluggable (SFPs) for its three controllers. To check the presence and link status of the SFP, use the show controllers modular-cable sfp command. If the SFP is not present, the output will display:
SFP in Port1 is NOT PRESENTIf the SFP is present, verify that the "Phy Port" status is "Up"
•
To verify bidirectional communication between the Cisco CMTS and the RF Gateway, run the show ip interfaces brief command.
The Cisco uBR-MC3GX60 line card has three Gigabit Ethernet interfaces. When an IP address is configured on the GigE interface in a subnet that includes the RF Gateway, the IP address of the RF Gateway becomes pingable.
For more information on troubleshooting, see the Cisco DOCSIS 3.0 Downstream Solution Design and Implementation Guide.
For complete descriptions of the above configuration commands, see the Cisco IOS CMTS Cable Command Reference on Cisco.com.
Upgrading Cisco uBR10-MC5X20S/U/H or Cisco UBR-MC20X20V Line Cards to Cisco uBR-MC3GX60V Cable Interface Line Card
The Cisco IOS Release 12.2(33)SCE does not support online insertion and removal (OIR) compatibility for the Cisco uBR-MC3GX60V line card. To upgrade to the Cisco uBR-MC3GX60V line card from the Cisco uBR10-MC5X20S/U/H or Cisco UBR-MC20X20V line cards, you must remove the existing configuration of the line card using the no card command and create a new configuration for the Cisco uBR-MC3GX60V line card.
