OIR of Cable Interface Line Cards on the Cisco uBR10012 Universal Broadband Router
The Cisco uBR10012 series universal broadband routers support online insertion and removal (OIR) of
cable interface line cards only when exchanging cable interface line cards of the same type.
Effective with Cisco IOS Release 12.2(33)SCC, OIR compatibility between the Cisco uBR10-MC5X20
and the Cisco UBR-MC20X20V line cards is supported. The OIR compatibility procedure translates the
configuration from one format to another during the OIR process.
Prerequisites for Performing OIR
•
Save the line card configuration before starting the OIR.
•
Perform OIR when the CMTS is up and running.
•
Change the standby card (if available) to HOT state.
•
Save the startup configuration file before any reload of the system (if there is a need to reload), after
a successful OIR.
Restrictions During OIR Process
Note
The Cisco uBR-MC3GX60V line card does not support OIR compatibility. To upgrade to the
Cisco uBR-MC3GX60V line card from the Cisco uBR10-MC5X20H 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.
•
OIR upgrade cannot be performed when the standby PRE is being loaded.
•
OIR downgrade from the Cisco UBR-MC20X20V line card to the Cisco uBR10-MC5X20 line card
may fail in certain scenarios when the frequency and RF power settings on the
Cisco UBR-MC20X20V line card are incompatible with the Cisco uBR10-MC5X20 card.
Performing an OIR of a Cable Interface Line Card
Step 1
In global configuration mode, enter the cr10k card oir-compatibility command for the cable interface
line card to perform an OIR, as shown in the following example:
Router(config)# cr10k card 8/0 oir-compatibility
This command helps preserve the configuration and performs some internal synchronization to make
sure that the OIR runs successfully.

Note
Step 2
Effective with Cisco IOS Release 12.2(33)SCC, OIR compatibility is automatically ON for all
slots of the line cards.
Save the configuration to ensure the transition, as shown in the following example:
Router# copy running-config startup-config
Step 3
Turn the power off to the line card using the cable power off command for the slot that is being replaced,
as shown in the following example:
Router# cable power off 8/0
Line Card 8/0 is POWERED OFF
This powers off the line card gracefully.
Step 4
Before removing the card, verify that the proper grounding instructions have been followed for the card.
Step 5
Remove the line card.
Step 6
Replace it with the new line card in the slot.
Step 7
Enter the cable power on command to power up the line card, as shown in the following example:
Router# cable power on 8/0
Step 8
Enter the show interface cable command and verify that the card and line protocol is “up” as shown in
the following example:
Router# show interface cable 8/0/0
Cable8/0/0 is up, line protocol is up

Feature Support
Cisco IOS software is packaged in feature sets that consist of software images that support specific
platforms. The feature sets available for a specific platform depend on which Cisco IOS software images
are included in a release. Each feature set contains a specific set of Cisco IOS features.
Caution
Cisco IOS images with strong encryption (including, but not limited to 168-bit [3DES] data encryption
feature sets) are subject to U.S. government export controls and have limited distribution. Strong
encryption images to be installed outside the United States are likely to require an export license.
Customer orders may be denied or subject to delay because of U.S. government regulations. When
applicable, the purchaser or user must obtain local import and use authorizations for all encryption
strengths. Please contact your sales representative or distributor for more information, or send an e-mail
to [email protected].

policy rules specifically to upstream or downstream throughputs. It is implemented through
DOCSIS policy implementation.
•
Configurable min-threshold of utilization method: This enhancement seeks to make minimum load
utilization value for load balancing using utilization method, configurable. This is implemented
through the cable load-balance method-utilization min-threshold command.
•
Display status information of modem-list in a LB group: This enhancement seeks to provide
additional information for a modem list in a DOCSIS LB group. This is implemented by modifying
the output of show cable load-balance docsis-group command
•
Default settings for D3.0/D2.0 GLBG: This enhancement seeks to provide additional default
configuration settings for DOCSIS 2.0 GLBG. This enhancement provides support to the
Auto-generate DOCSIS 2.0 GLBG enhancement. This is implemented through modification of the
cable load-balance d30-ggrp-default and cable load-balance d20-ggrp-default commands.
•

rule.
•
Exclude modems CLI enhancement: This enhancement seeks to exclude old devices not supporting
load balancing features from a load balancing group. This is implemented by modifying the cable
load-balance exclude command.
•
Static LB based on primary channel load for bonded modems: Status of primary load can be
ascertained using the primary-load keyword.
The following commands were introduced or modified:
•
cable load-balance d20 GLBG auto-generate

Introduction
New and Changed Information
Features Integrated in Cisco IOS Release 12.2(33)SCH1
MIB Enhancements for USCB CM
Effective from Cisco IOS Release 12.2(33)SCG5, MIB enhancements for upstream channel bonding
group (USCB) cable modems (CMs) is implemented. The MIB enhancement provides Transmit Channel
Set (TCS) and service flow information.
For more information, see the Cisco CMTS Universal Broadband Router Series MIB Specifications
Guide at:
http://www.cisco.com/en/US/docs/cable/cmts/mib/12_2sc/reference/guide/ubrmibv5.html
Upstream Drop Classifier
A set of matching criteria is applied by the cable modems to packets to determine if a packet should be
dropped. This set of matching criteria when applied to upstream traffic, is called the Upstream Drop
Classifier (UDC). The CMTS only enables the UDC feature on the cable modems.
Effective from Cisco IOS Release 12.2(33)SCG5, the UDC feature can be enabled for all cable modems
on any interface of a Cisco uBR10012 or Cisco 7200 Series router by using the cable udc-capability
command in interface configuration mode.
The following command were introduced or modified:
•
cable udc-capability
•
show cable modem
For more information on the UDC feature, see the Configuring Upstream Cable Interface Features on
the Cisco CMTS Routers guide at the following URL:
http://www.cisco.com/en/US/docs/ios/cable/configuration/guide/cmts_upstrm_if.html

Features Integrated in Cisco IOS Release 12.2(33)SCH
Cable Modem System Description
The show cable modem sysDescr command, introduced in Cisco IOS Release 12.2(33)SCG2, provides
the system description of a single cable modem without enabling remote query on the Cisco CMTS
router. The show cable modem sysDescr command displays result for IPv4 cable modems only.
In Cisco IOS Release 12.2(33)SCG1 and earlier, you cannot view the system description of a single cable
modem. Instead, you can view system descriptions of all cable modems after enabling remote query on
the Cisco CMTS router using the cable modem remote-query command in global configuration mode.
This might impact system performance because it queries all the cable modems connected to the Cisco
CMTS router.

Copy and Paste Support for TDMA to ATDMA Upgrade
To have the 6400 kHz channel width accepted by pasting the configuration only once,
Cisco IOS Release 12.2(33)SCG2 introduces the Copy and Paste Support for TDMA to A-TDMA
Upgrade feature. If 6400 kHz is set as channel width in TDMA mode or mixed TDMA/A-TDMA mode,
DOCSIS mode automatically changes to A-TDMA-only (DOCSIS 2.0) mode.
The following commands were modified:
•
cable upstream channel-width
•
cable upstream docsis-mode

DEPI CIN Failover
The depi cin-failover command enables CIN failure triggered line card switchover when DEPI control
plane is used, and N+1 is configured. When the CPU utilization is high, DEPI CIN failover may get
rejected. Starting Cisco IOS Release 12.2(33)SCF4 and later, cpu-threshold values can be configured
using the depi cin-failover cpu-threshold command.

Software Feature Restrictions
This section describes other important guidelines or restrictions to consider when running Cisco IOS
Release 12.2SC that might not yet be documented in the supporting customer documentation.
DOCSIS 3.0 Load Balancing
Note
Effective with Cisco IOS Release 12.2(33)SCG1, the Cisco uBR-MC3GX60V line card and up to five
Cisco Wideband SPAs can be configured to the same LBG.
DOCSIS
•
You cannot configure a US connector to more than one fiber node.
•
Multicast over DOCSIS L2VPN does not work for a DOCSIS 3.0-bonded cable modem (CM) when
DOCSIS L2VPN is provisioned on a DOCSIS 3.0-bonded CM and downstream multicast traffic is
sent over L2VPN. You can use a DOCSIS L2VPN classifier to classify multicast traffic on a
secondary DS service flow with SF attributes (TLV 25.31/32) specifying primary DS for the CM.
As a result, L2VPN multicast traffic uses the primary DS and L2VPN unicast traffic is forwarded
over the primary bonding group. The service flow attribute feature is available in Cisco IOS Release
12.2SCB.

Introduction
Limitations and Restrictions
DTI Card Configuration
The Cisco uBR10012 universal broadband router TCC card does not work as expected when the startup
configuration contains the configuration for a Cisco uBR10012 universal broadband router TCC+ card.
To fix this issue, use the no card slot/subslot 2cable-tccplus command and then configure the DTI card.
MIBs Restrictions
•
IP-MIB is implemented as read-only. Writing is not supported for ipv6IPForwarding or
ipv6IpDefaultHopLimit.
•
docsIf3MdCfgMcastDsidFwdEnabled object is implemented as read-only.
•
cdxBWQueueMaxDepth object sometimes reports a value out of range. The supported range is from
0 to 64, but the object sometimes returns a value of 128 when queried.
PacketCable
Payload Header Suppression (PHS) is not supported on wideband Embedded Media Terminal Adapters
(eMTAs) for dynamic downstream service flows.
PXF
Statistics for two different divert-rate limit (DRL) WAN-IP streams can momentarily overlap or collide
and produce statistics that are lower than expected.
Redundancy
•
Longer dropout times (about 6 seconds) can occur when you use the OIR method to trigger a cable
line card switchover on the Cisco uBR10012 router. To repair or maintain a cable line card and get
better switchover performance, use the redundancy linecard-group switchover command to
trigger the line card switchover instead.
•
Although the software does not prevent it, preconfiguring commands on a protect line card is not
supported.
•
A dynamic service-flow for a PacketCable call is not deleted during a line card switchover.
•
Although the Cisco CMTS router is initially configured only for global N+1 redundancy, the show
running-configuration command displays both global and legacy interface-level Hot-Standby
Connection-to-Connection Protocol (HCCP) configuration when you change the redundancy mode
configuration from SSO to RPR mode. If you switch back to SSO mode, both redundancy
configurations are still shown.
•
In very rare circumstances, after an N+1 switchover, upstream traffic that is using Baseline Privacy
Interface (BPI) encryption is not received properly by the CMTS router. Input errors are logged on
the interface and the debug cable error command shows error messages similar to the following:
Cable5/1/4: Bad rx packet. JIB status code 0xA
The issue occurs on upstream channels that use a shared connector, where the other upstream
channel using the same shared connector is on another downstream and is shutdown. To workaround
this issue, you can activate the downstream and other upstream channel using the same shared
connector or temporarily unshare the upstream connector.

Chapter 1
Introduction
Important Notes
Wideband
If you configure a wideband interface with more than one MAC domain host sharing the committed
information rate (CIR) bandwidth, then the total wideband interface CIR bandwidth gets fragmented
among the MAC domain (MD) hosts sharing the wideband interface CIR bandwidth.
The WB interface CIR bandwidth can be shared by multiple MAC domain hosts, and these MAC domain
hosts could potentially be on the same or different cable line cards. As admission control for WB
interfaces occurs on cable line cards, the available CIR bandwidth gets partitioned and is given to the
MD hosts causing the bandwidth fragmentation. However if a typical service flow CIR is very small
compared to the total CIR of the wideband interface, then this fragmentation is not visible until the CIR
usage reaches very high levels close to the total interface bandwidth.
With certain bandwidth percentage configuration and traffic distribution, the overall link utilization of
dynamic bandwidth sharing (DBS) can be as low as 85 percent. For example, this can occur if the traffic
rate on a wideband interface is smaller than its configured bandwidth percentage, but the traffic rate on
a modular-cable interface is much larger than its bandwidth percentage. The packet drops occur only on
the modular-cable interface which has a larger amount of traffic than its bandwidth-percentage. To
workaround this scenario, configure a higher bandwidth percentage to the modular-cable interface,
which is larger than or equal to its expected or average traffic rate.

A vulnerability in the implementation of the
Network Time Protocol (NTP) feature in Cisco
IOS Software could allow an unauthenticated,
remote attacker to cause an affected device to
reload, resulting in a denial of service (DoS)
condition.
The vulnerability is due to the improper handling
of multicast NTP packets that are sent to an
affected device encapsulated in a Multicast
Source Discovery Protocol (MSDP)
Source-Active (SA) message from a configured
MSDP peer. An attacker could exploit this
vulnerability by sending multicast NTP packets to
an affected device. Repeated exploitation could
result in a sustained DoS condition.
Cisco has released free software updates that
address this vulnerability. A workaround is
available to mitigate this vulnerability.
