Note
The Cisco uBR-MC28U line card is not supported in Cisco IOS Release 12.2(33)SCH and later.
OIR of Cable Interface Line Cards on the Cisco uBR7200 Universal Broadband Router
The Cisco uBR7200 series universal broadband routers support online insertion and removal (OIR) or
“hot swapping” of cable interface line cards only when exchanging cable interface line cards of the exact
type. For example, exchanging a Cisco uBR-MC88V card for another Cisco uBR-MC88V line card.
Under these conditions, no reload of the router is required. When you perform OIR of different types of
cable interface line cards, you might not only have to reconfigure the interfaces, but also reload the router
(recommended).
Caution
Note
In the Cisco uBR7225VXR or Cisco uBR7246VXR router running Cisco IOS Release 12.2(33)SCD and
later, the Cisco uBR-MC88V cable interface line card cannot be “hot swapped” with another type of line
card. It cannot coexist with another type of line card in the same chassis.
Port adapters are not supported by the Cisco uBR7200 series routers in
Cisco IOS Release 12.2(33)SCH.

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.
The UDC feature is integrated into the Cisco IOS Release 12.2(33)SCH1 and can be enabled for all cable
modems on any interface.
The following commands were introduced or modified:
•

Features Integrated into 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.
For more details about the show cable modem sysDescr command, see the Cisco IOS CMTS Cable

Limitations and Restrictions
Limitations and Restrictions
This section describes restrictions for the Cisco universal broadband routers in
Cisco IOS Release 12.2(33)SCH.
Unsupported Hardware
For a list of unsupported hardware, see the End-of-Life and End-of-Sale Notices at the following URLs:
•
http://www.cisco.com/en/US/products/hw/cable/ps2217/prod_eol_notices_list.html
•
http://www.cisco.com/en/US/products/hw/cable/ps2209/prod_eol_notices_list.html
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
•
You cannot configure an upstream connector on 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.
•
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.
MIBs Restriction
PacketCable
Payload Header Suppression (PHS) is not supported on wideband Embedded Media Terminal Adapters
(eMTAs) for dynamic downstream service flows.
Redundancy
•
Although the software does not prevent it, pre-configuring 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.
Cisco uBR7200 Router Release Notes for Cisco IOS Release 12.2(33)SCH

Chapter 1
Introduction
Important Notes
•
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
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.
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 hosts sharing the WB 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 happens on cable line cards, the available CIR bandwidth gets partitioned and 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 percent configuration and traffic distribution, the overall link utilization of
dynamic bandwidth sharing (DBS) can be 85%. For example, this can occur if the traffic rate on a
wideband interface is smaller than its configured bandwidth percent, but the traffic rate on a
modular-cable interface is much larger than its bandwidth percent. The packet drops happen only on the
modular-cable interface which has a larger amount of traffic than its bandwidth-percent. 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.

Wideband cable modem is online using a
Wideband-Cable interface that has less channels
than it is capable of bonding even when a higher
channel Wideband-Cable interface is available for
the modem to use. This occurs when a modem
capable of 16 or 24 channels initially acquires on
a Modular-Cable controller that only has a 4
channel Receive Channel Configuration (RCC)
and is then steered to a different Modular-Cable
controller with 4, 8, and 12 channel RCC
available. When the cable modem moves to the
controller with 12 channels available, load
balancing configures a 4 channel RCC for the
modem.
