Software Compatibility

Cisco IOS-XE release represents the continuing evolution of Cisco's pre-eminent IOS operating system.

Cisco IOS-XE release retains the exact same look and feel of IOS, while providing enhanced future-proofing and improved functionality. In Cisco IOS-XE Release 3.2SQ, the Cisco IOS Release 15.0(2)SQA runs as a single daemon within a modern Linux operating system. Additional system functions now run as additional, separate processes in the host OS environment. The operation, support and management of IOS-XE does not require re-training from classic IOS.

Cisco IOS-XE Release 3.2SQ includes the IOSd 15.0(2)SQA daemon, inherits features from previous classic IOS 12.2(50)SQ releases and is the base release for a new maintenance train. Cisco IOS Release 12.2(50)SQ is the last maintenance train supporting the Cisco RFGW-10 Supervisor V-10GE. Cisco IOS-XE Release 3.2.0SQ introduces the Cisco RFGW Supervisor 7-E and the Cisco RFGW-10 DS-384 line card.

The following figure shows the software release trains for Cisco RFGW-10. This figure is only indicative of the progression of the release trains.

New Software Features in Cisco IOS-XE Release 3.2.0SQ

This section describes the new software features supported in Cisco IOS-XE Release 3.2.0SQ.

Cisco RFGW-10 DS-384 RF Port Configuration

The Cisco RFGW-10 DS-384 line card is a high-density card and has the following features:

  • Maximum of eight RF ports on every line card.
  • RF ports support different densities—1, 2, 4 and up to 128 QAMs per port in increments of 4.
  • A total of 128 QAMs per line card is supported in this release.
  • The default frequency assignment mode is supported. This enables the user to define the start frequency of the RF output spectrum and automatically configures the port for 768 MHz of contiguous spectrum. Users can assign QAM channels anywhere within the configured spectrum.
  • Carrier spacing of +/- 6 MHz is supported for Annex B and C, and +/- 8MHz for only Annex A.
  • A logical QAM (LQAM) channel is a single RF carrier.
  • An LQAM group is a group of eight LQAM channels that share the same RF parameters in an RF profile. For more information, see Configuring the Cisco RFGW-10 DS-384 Line Card .

Software Licensing on the Cisco RFGW-10 DS-384 Line Card

The Cisco RFGW-10 licenses are used to control access to the RF channels. It supports QAM-capacity licensing where a customer can invest in partial QAM-capacity of the line card. Table 4 lists the licenses for the Cisco RFGW-10 DS-384 line card.

Licensing Flavors

Cisco RFGW-10 DS-384 line card

Cisco IOS-XE Release 3.2.0SQ

The stock keeping unit (SKU) for the Cisco RFGW-10 DS-384 line card are:

  • SWLIC-DS384-BUN (DS-384 QAM license (single QAM) bundle)
  • SWLIC-DS384 (DS-384 QAM license (single QAM)
  • L-DS384 (DS-384 QAM Upgrade Licenses (single QAM)

Manual DEPI Configuration

Starting Cisco IOS-XE Release 3.2.0SQ, the 32-bit session IDs are generated internally for the DEPI sessions, and is configured manually on the M-CMTS node, thus improving the performance of the system with higher session load for new line cards.

In Cisco IOS-XE Release 3.2.0SQ, all QAM channels on the RF port can be used for DEPI when the QAM subinterface is configured for DEPI. A QAM-port load-balancing group is a QAM block or midplane 10 Gigabit-Ethernet interface. Two QAM-port load-balancing groups exist per line card and a QAM-port load-balancing group is assigned to QAM channels while configuring local DEPI sessions.

The QAM channels are equally divided between the two QAM-port load-balancing groups on any line card. Each QAM port load-balancing group supports 192 carriers for the Cisco RFGW-10 DS-384 line card, and 24 carriers for the Cisco RFGW-10 DS-48 line card. The show cable linecard load-balancing-group command lists the current carriers on the line card.

For more information, see M-CMTS DEPI .

1:1 and 1:N Line card Redundancy

The Cisco RFGW-10 DS-48 and Cisco RFGW-10 DS-384 line cards have different ports, hence cannot be used in the same redundancy group. Starting with Cisco IOS-XE Release 3.2.0SQ, the Cisco RFGW-10 supports multiple line card types. Table 5 lists the line card redundancy compatibility between the Cisco RFGW-10 line cards within the same redundancy group.

In addition, the Cisco RFGW-10 supports MIBs common in Cisco IOS, which can be found in the Cisco RF Gateway 10 MIB Specifications Guide .

Limitations and Restrictions

This section lists the limitations and restrictions for the Cisco IOS-XE Release 3.2SQ train on the Cisco RFGW- 10.

  • Only DOCSIS data is supported.
  • Only 128 RF channels are supported on the Cisco RF Gateway 10 DS-384 for this release.
  • Cisco IOS-XE Release 3.2.0SQ and Cisco IOS-XE Release 3.2.1SQ do not support management port. Support starts in Cisco IOS-XE Release 3.2.2SQ.

Note In Cisco IOS-XE Release 3.2.0SQ and Cisco IOS-XE Release 3.2.1SQ, the configuration for the management port always appears in the running configuration in shutdown state. The configuration cannot be changed to the no shut state.


  • When you use the Cisco RFGW-10 Supervisor 7-E in redundancy mode, the top two front panel uplink ports on the slot 2 supervisor are available for data and management traffic. However, the path between the uplink ports on a standby slot 1 Supervisor and active slot 2 Supervisor has detectable bit errors. Thus, the front panel uplink ports on the slot 1 supervisor are not suitable for data and management traffic in redundancy mode.
  • Cisco IOS-XE Release 3.2.0SQ and Cisco IOS-XE Release 3.2.1SQ do not support auto-negotiation on Cisco RFGW-10 DS-384 line card ports 9 and 10 with 1 Gbps SFPs. Support starts in Cisco IOS-XE Release 3.2.2SQ
  • Online insertion and removal (OIR) of active Supervisor card is not supported. You must force switchover to the standby Supervisor card before removing the active card.
  • Static remote DEPI is not supported.
  • Cisco IOS-XE Release 3.2.0SQ and Cisco IOS-XE Release 3.2.1SQ do not support Etherchannel. Limited support starts in Cisco IOS-XE Release 3.2.2SQ.
  • Annex A is not supported in the Cisco IOS-XE Release 3.2.0SQ.

Note Effective with Cisco IOS-XE Release 3.2.1SQ Annex A is supported.


  • Direct image downgrade to Cisco IOS-XE Release 3.2.0SQ is not supported from releases later than Cisco IOS-XE Release 3.2.1SQ. Image must first be downgraded to Cisco IOS-XE Release 3.2.1SQ before being downgraded to Cisco IOS-XE 3.2.0SQ.

Note This limitation applies only to Cisco IOS-XE Release 3.2.0SQ.

Resolved Caveats for Cisco IOS-XE Release 3.2.2SQ

 

Caveat
Description

CSCtw57111

Symptom: The show interface qam command output displays incorrect bandwidth values when executed at the port level.

Conditions: This issue is observed on the Cisco RFGW-10 DS-48 line card.

Workaround: There is no workaround.

CSCtx99408

Symptom: The standby Supervisor goes into Route Processor Redundancy (RPR) mode if rf-profile with invalid interleaver-depth value is applied to the QAM channel.

Conditions: This issue occurs while configuring rf-profile on the line cards. When the rf-profile is applied to a QAM Channel, the system automatically applies the interleaver-depth value from the rf-profile to the QAM Channel. This invalid configuration causes a configuration synchronization failure and results in the standby Supervisor going to RPR mode.

Workaround: Set default values on QAM channel and perform a redundancy reload of the Cisco RFGW-10.

CSCtz92104

Symptom: Error message are seen on the Supervisor console when the first clock source is connected to the TCC card:

Conditions: This issue occurs when the TCC cards have no clock sources and the first clock source is connected to a TCC. The active TCC card goes into fast mode, re-acquiring the lock. The Cisco RFGW-10 DS-384 line card upconverter loses and re-acquires the lock.

Workaround: There is no workaround.

Ignore this incorrect error message. The upconverter will lose and re-acquire the lock when the TCC cards lose and re-acquire the lock. This is expected behavior

CSCua58184

Symptom: Error messages are seen on the Supervisor console when a line card is inserted into a slot:

Conditions: This issue occurs if the Supervisor card is unable to read the serial EEPROM (SEEPROM) of the line card when the card is being slowly inserted into the chassis.

Workaround: Reinsert the line card. The Supervisor card is successful in reading the EEPROM in the second attempt.

CSCua99738

Symptom: The show inventory command output displays the TCC card hardware revision value incorrectly.

Conditions: This issue occurs on normal conditions.

Workaround: Use the show idprom module module-number command to view the correct TCC card versions.

CSCub01890

Symptom: The following error message is displayed:

TCC_ERRMSG_GEN_LCD_BUSY_TIMEOUT
 

Conditions: This issue occurs after the TCC card switchover.

Workaround: There is no workaround. This issue has no service-affecting impact.

CSCub01894

Symptom: After the line card redundancy is removed, previous configuration of the new independent card (prior to configuring redundancy) are still preserved and an attempt to bring up the sessions fails.

Conditions: This issue occurs under normal conditions.

Workaround: Before configuring the stand alone line card as a secondary line card, default all QAM ports of the line card to be configured, as secondary.

Router(config)# default interface Qam <slot>/<port>
 

or manually remove all the configuration for that line card slot in the newly independent card.

CSCub34355

Symptom: The following error message is displayed:

ERROR: Qam <slot>/<port> is administratively shut and will reject the configuration.

Conditions: This issue occurs when the default configuration is applied to the port that is in shutdown state.

Workaround: If the port is admin_down state, unshut the port before applying the default configuration at the port level.

CSCub46436

Symptom: Continuous “Up/down reason: QC RF Mute mismatch” messages are observed on the Cisco RFGW-10.

Conditions: This issue occurs when DEPI remote-learn QAM sessions exist on the Cisco RFGW-10 and few QAM licenses exist for the configured QAM channels.

Workaround: Upgrade the line card to have enough QAM licenses for all configured QAM channels.

CSCub46770

Symptom: Modems go from w-online to online(pt) state when the modulation is changed to 64 and then reverted back to 256.

Conditions: This issue occurs when the modulation is directly modified.

Workaround: Remove the frequency modulation using no form of the command and reapply.

Example:

router# configure terminal
router(config)# controller modular-cable 5/0/0
router(config-controller)# no rf-channel 0 frequency
router(config-controller)# rf-channel 0 frequency 555000000 annex B modulation 64 interleave-depth 32
 

CSCub73486

Symptom: The LQAM configuration is rejected with the following error:

All carrier id for slot 3 have been used. Carrier id is not assigned. Cannot add lqam group or sessions for Qam3/7.26
Error: Invalid lqam group id 45 for Qam3/7.26
 

Conditions: This issue occurs if a saved configuration is copied from a storage device to the running configuration after the RF Gateway 10 is booted up with all default configurations.

Workaround: Remove the carrier ID command from the saved configuration and then apply it onto the running configuration.

CSCub82362

Symptom: For the Cisco RFGW 10 DS-384 line card, auto-negotiation is not supported on ports 9 and 10 with 1 Gbps SFPs.

For a scenario where a primary port on the Cisco uBR-MC3GX60V line card is directly connected to ports 9 or 10 of the Cisco RFGW 10 DS-384 line card and primary port link is restored, the backup port still remains active because the primary port does not complete autonegotiation.

Conditions: This issue occurs under normal conditions.

Auto-negotiation is disabled by default on ports 9 and 10 when using 1 Gbps SFPs. Auto-negotiation remains disabled even after the user enables it from the management system. With port redundancy, the Cisco uBR-MC3GX60V line card always checks for auto-negotiation completion before allowing a failed primary port to return to active state. This behavior does not change even after the user tries to disable auto-negotiation on the Cisco uBR-MC3GX60V primary port.

Workaround: Use ports 11 and 12 instead of ports 9 and 10. For ports 9 and 10, configure connected devices for 1 Gbps speed, full duplex, and with auto-negotiation off. With Cisco uBR-MC3GX60V line card port redundancy, use Cisco RFGW 10 DS-384 ports 11 and 12 for primary connections and use ports 9 and 10 for backup and non-redundant connections.

CSCub88510

Symptom: Error message is reported on the Supervisor console by the Cisco RFGW-10 DS-384 line card indicating that an RF power level event has occurred.

Conditions: This issue occurs after issuing hw-module reset command.

The "RF power level out of spec" event is generated due a transient power fluctuation when the arrival of traffic to a port is delayed due to a rare race condition during the un-mute of a QAM carrier on a port.

Workaround: Perform the RF port interface level shutdown and no shutdown to restore any DEPI sessions on port. If any operational issues follow the hardware module reset (with RF power level event), perform a software reset of the DS-384 line card using the cable linecard reset command to re-program the upconverter module.

The hw-module reset command resets a given line card and simulates a power cycle of the line card. If any line card reset is performed during normal operation with redundancy configuration, service is maintained by the secondary designated line card.

CSCuc10713

Symptom: QAMs are stuck in “Idle” state.

Conditions: This issue occurs when multiple line card failures occur before the revertive timer expires.

Workaround: Wait till the revertive timer expires and the revertive switchover completes before initiating another line card failover. Reload the Cisco RF Gateway 10 chassis to recover from the error.

CSCuc13374

Symptom: The following error message is observed on the active and standby Supervisor cards when using default settings for a qam-channel:

'ERROR: This Interleave delay is not supported by the qam's rf-profile 6'

Conditions: This error message appears during default of the channels in which the RF-profiles have interleaver depth values other than I32-J4.

Workaround: Associate rf-profile with interleaver depth values as I32-J4.

CSCuc27292

Symptom: The RF profile is not removed even when the no cable downstream rf profile command is accepted without any errors or warnings.

Conditions: This issue occurs when the RF profile is removed while still applied to the QAM interface. The command to remove the RF profile is accepted, but the RF profile is not removed.

Then even after the no cable downstream rf profile command is run to remove the RF profile from the interface, the RF profile is still displayed in running configuration.

Workaround: Reset the interface that the RF profile was applied to, using the default interface command.

The following error messages appears when you default the interface, but this is expected behavior:

ERROR: Rf Profile mismatches group's profile for Qam 4/7:1

CSCuc27709

Symptom: Line card in slot 12 cannot be configured as the primary line card to a redundancy group when the line card in slot 11 is configured as a secondary.

Conditions: This issue occurs when the line card in slot 11 is configured as secondary before configuring line card-12 a primary.

Workaround: Configure line card-12 as primary before configuring the redundancy group.

CSCuc37532

Symptom: Remote RF profiles created on the Supervisor display the same symbol rate for both Annex-B 256qam and Annex-B 64qam.

Conditions: This issue is only a display issue on the Supervisor. In reality, the line card uses the correct symbol rate when 256qam is configured.

Workaround: There is no workaround.

CSCuc45114

Conditions: This issue occurs in normal conditions.

Workaround: Use the show idprom chassis command to get both parent and child serial number.

CSCuc56647

Symptom: Traceback occurs when a new remote RF profile is created.

Conditions: This issue occurs when there are 16 RF profiles existing in the system. The maximum number of RF profile in the systems is 16, and that limit is reached.

Workaround: Check the number of existing RF profiles before creating a new one.

CSCuc58675

Symptom: A Qam-redundancy port configured as shutdown comes up in "UP" state instead of remaining in shutdown state.

Conditions: This issue occurs if the secondary line card initially goes in active state following the reset of both the primary and secondary line cards.

Note This issue affects only the running-configuration and not the startup-configuration.

Workaround: Manually configure the Qam-red port as shutdown.

CSCuc69406

Symptom: The primary Supervisor card crashes after the Cisco CMTS is reconfigured with a frequency change.

Conditions: This issue occurs when RF channels are reconfigured with 6Mhz shifted frequencies. and the last frequency overlaps with another existing RF channel on another controller that has same frequency.

Workaround: There is no workaround. However, fix the frequency overlap to recover the overlap channel.

CSCuc90077

Symptom: The show inventory oid command displays an incorrect OID value for the Cisco RFGW-10 DS-384 line cards.

Conditions: This issue occurs under normal conditions.

Workaround: There is no workaround.

CSCud03215

Symptom:

Modems fall offline after a hw-module reset of the secondary line card is performed.

Conditions:

This issue occurs under the following conditions:

1. Slot 11 is a primary line card and slot 12 is the secondary line card

2. A line card switchover from slot 11 to slot 12 is performed.

3. A line card switchover back from slot 12 to slot 11 is performed using the hw-module module 12 reset command.

Modems drop offline and services through these modems are disrupted.

Workaround:

Avoid using the hw-module module 12 reset command. Instead, use the redundancy linecard switchover command from slot 12 to revert back.

command only does a soft reset of slot 12.

To perform a hard reset:

1. redundancy linecard switchover from slot 12.

2. hw-module module 12 reset

This triggers a hard reset. Because slot 12 is in a standby state, the hard reset does not affect services.

%COMMON_FIB-3-FIBIDBEARLYCALL: STANDBY:Attempt to update fibidb prior to completion of idb initialization.

Conditions:

This issue occurs the Cisco RFGW-10 DS-384 line card is inserted in a slot after removing the Cisco DS-48 line card.

Workaround:

Reset the line card in the slot.

CSCub82362

Symptom:

For the Cisco RFGW 10 DS-384 line card, autonegotiation is not supported on ports 9 and 10 with 1 Gbps SFPs.

For a scenario where a primary port on the Cisco uBR-MC3GX60V line card is directly connected to ports 9 or 10 of the Cisco RFGW 10 DS-384 line card and primary port link is restored, the backup port still remains active because the primary port does not complete autonegotiation.

Conditions:

This issue occurs under normal conditions. Autonegotiation is disabled by default on ports 9 and 10 when using 1 Gbps SFPs. Autonegotiation remains disabled even after the user enables it from the management system. With port redundancy, the Cisco uBR-MC3GX60V line card always checks for autonegotiation completion before allowing a failed primary port to return to active state. This behavior does not change even after the user tries to disable autonegotiation on the Cisco uBR-MC3GX60V primary port.

Workaround:

Use ports 11 and 12 instead of ports 9 and 10. For ports 9 and 10, configure connected devices for 1 Gbps speed, full duplex, and with autonegotiation off. With Cisco uBR-MC3GX60V line card port redundancy, use Cisco RFGW 10 DS-384 ports 11 and 12 for primary connections and use ports 9 and 10 for backup and non-redundant connections.

CSCub87522

Conditions:

This issue occurs when a file is copied to the USB device.

Workaround:

There is no workaround. The system retries the read and write operation and the error is recovered automatically.

CSCub89864

Symptom:

The following error message is seen on active Supervisor console when the standby Supervisor comes up after a redundancy switchover.

%C4K_SUPERVISOR-3-INITERROR: STANDBY:Packet switching asic init failure. Requires reboot.

Conditions:

This issue occurs when the primary line card is reset/removed and the switchover happens simultaneously.

Workaround:

There is no workaround. This issue occurs rarely because of an initialization issue, which completes upon retry.

CSCub95552

Symptom:

Cable modems flap when the line card switchover is initiated using the cable linecard reset command.

Conditions:

This issue occurs with line card in slot 11 to line card in slot 12 switchovers. However, this issue can happen on any line card switchover.

Workaround:

Do not use the cable linecard reset command. Instead use the redundancy linecard switchover command.

CSCuc01025

Symptom:

After a Supervisor switchover, when executing the configuration to remove the line card redundancy, the standby supervisor silently reloads itself.

Conditions:

This issue occurs under normal conditions.

Workaround:

There is no workaround. The standby supervisor resets itself and comes back healthy without any issues. No manual intervention is required.

CSCuc01153

%RFGW-3-UNEXPECTED: Invalid response received for HW CNFG QAM message

Conditions:

This issue occurs while configuring line card redundancy with remote DEPI configurations followed by a reset of the line card.

Workaround:

Reload the Cisco RF Gateway 10 chassis.

CSCuc02064

Symptom:

If the line card switchover and Supervisor card switchover occur with a few seconds of each other, the QAM channels are moved to muted state.

Conditions:

This issue occurs while performing a line card switchover within a few seconds of a Supervisor card switchover.

Workaround:

Reset the primary and secondary line cards.

CSCuc02232

Symptom:

After the online insertion and removal (OIR) of the Cisco RFGW 10 DS-384 line card, some "idle" DEPI sessions are also displayed in the output of the show cable depi l2tp command.

Conditions:

This issue occurs only on a standalone DS-384 line card and when line card redundancy is not configured.

Workaround:

There is no workaround; sessions are cleared once they are timed out. No manual intervention is needed.

CSCuc10713

Symptom:

QAMs are stuck in "Idle" state.

Conditions:

This issue occurs when multiple line card failures occur before the revertive timer expires.

Workaround:

Wait till the revertive timer expires and the revertive switchover completes before initiating another line card failover. Reload the Cisco RF Gateway 10 chassis to recover from the error.

CSCuc13374

Symptom:

The following error message is observed on the active and standby Supervisor cards when using default settings for a qam-channel:

'ERROR: This Interleave delay is not supported by the qam's rf-profile 6'

Conditions:

This error message appears during default of the channels in which the RF-profiles have interleaver depth values other than I32-J4.

Workaround:

Associate rf-profile with interleaver depth values as I32-J4.

CSCuc24855

Symptom:

The QAM ports of a non-redundant Cisco RFGW 10 DS-384 line card are not displayed in the output of the show running-configuration command on the standby Supervisor card.

Conditions:

This issue occurs only on the Cisco RFGW 10 DS-384 line card in slot 11 or 12 after the card is unconfigured as a Secondary member of the line card redundancy group.

Any configuration of the QAM port of such line card can cause the standby Supervisor to detect a configuration mismatch condition resulting in the reboot of the standby Supervisor. After the standby Supervisor reboots, the condition is fully recovered.

Workaround:

There are two workarounds:

  • Reboot the standby Supervisor.
  • After the line card in slot 11 or 12 comes back up following its uncofiguration as a Secondary line card, run the hw module reset command to reset the line card.

CSCuc26905

Symptom:

CSCuc27292

Symptom:

The RF profile is not removed even when the no cable downstream rf profile command is accepted without any errors or warnings.

Conditions:

This issue occurs when the RF profile is removed while still applied to the QAM interface. The command to remove the RF profile is accepted, but the RF profile is not removed.

Then even after the no cable downstream rf profile command is run to remove the RF profile from the interface, the RF profile is still displayed in running configuration.

Workaround:

Reset the interface that the RF profile was applied to, using the default interface command.

The following error messages appears when you default the interface, but this is expected behavior:

ERROR: Rf Profile mismatches group's profile for Qam 4/7:1

CSCuc27709

Symptom:

Line card in slot 12 cannot be configured as the primary line card to a redundancy group when the line card in slot 11 is configured as a secondary.

Conditions:

This issue occurs when the line card in slot 11 is configured as secondary before configuring line card-12 a primary.

Workaround:

Configure line card-12 as primary before configuring the redundancy group.

CSCuc29309

Symptom:

The output for the show tech command is unable to get the boot log output from the Cisco RFGW-10 DS-384 line card flash.

Conditions:

This issue occurs when the system log files exceed 1 Mb in size and the Supervisor card logs an IPC failure message for the Cisco RFGW-10 DS-384 line card.

Workaround:

1. Telnet to the line card to manually convert the line card log from binary format to TXT:

On the line card console, do the following:

sloginfo /flash/slogs1 > /flash/slogs1.txt
sloginfo /flash/slogs2 > /flash/slogs2.txt
sloginfo /flash/slogs1_boot > /flash/slogs1_boot.txt

Conditions:

This issue occurs when the RF profile that is being changed is applied to a QAM interface.

Workaround:

There is no workaround.

CSCuc37532

Symptom:

Remote RF profiles created on the Supervisor display the same symbol rate for both Annex-B 256qam and Annex-B 64qam.

Conditions:

This issue is only a display issue on the Supervisor. In reality, the line card uses the correct symbol rate when 256qam is configured.

Workaround:

There is no workaround.

CSCuc39115

Symptom:

When a secondary line card, which is in Active state due to a line card switchover, is removed from a redundancy group, an error message is displayed:

ERR: Updating red sb for primary i/f 48 failed. Linecard redundancy is now in an inconsistent state.

CSCuc42319

Symptom:

During a Supervisor switchover, or during system boot up, the following message is displayed on the Supervisor console:

"%C4K_CHASSIS-6-XPOINTSWITCHRESET"

Conditions:

This issue is seen during a Supervisor switchover because the line card needs to reconnect to the new active Supervisor.

This message indicates that the line card has detected a backplane link failure between the line card and the active Supervisor. This link failure event was reported to the active Supervisor, which triggered an XPOINTSWITCH reset.

This message informs that a XPOINTSWITCH reset has been issued to recover the backplane links between the line card and the active supervisor.

Workaround:

There is no workaround.

The XPOINTSWITCH reset recovers from the link failure. Modems connected to the line card may temporarily drop offline.

CSCuc43664

Symptom:

All manual DEPI sessions are in "rf-shut" state.

Conditions:

This issue occurs after a combination of line card high availability, stateful switchover (SSO), and a hardware module reset.

Workaround:

To recover from this condition:

1. Run the no cable downstream rf-shut on each rf-shut channel.

2. Initiate a single SSO without saving the configuration.

This recovers all sessions.

Conditions:

This issue occurs under two conditions:

1. When the SNMP trap link status is removed from the QAM port when it is configured on a standalone line card and this line card is added to a redundancy group.

2. When SNMP trap link status is configured in Qam-redundancy port, SNMP traps are removed if there is a corresponding LC_IMAGE_UPGRADE event.

Workaround:

Reconfigure SNMP trap link status on the Qam port from where it is removed.

CSCuc49069

Symptom:

Remote DEPI ports are impaired after a series of line card high availability, stateful switchover (SSO), and a hardware module resets. DEPI session are displayed as Active, but modem do not come online.

Conditions:

This issue occurs when start frequency on the remote DEPI port is modified a few times before the line card high availability, SSO, and a hardware module reset combination.

Workaround:

To avoid this issue, save the configuration and reboot after changing the start frequency.

To recover from this issue, perform a shut/no shut of the RF port.

CSCuc53957

Symptom:

The QAM associated with the Cisco RFGW-10 DS-384 line card is removed if line card high availability and stateful switchover (SSO) are executed in a particular sequence.

Conditions:

This issue occurs when:

1. The secondary line card is initializing and the SSO is triggered

2. The next line card redundancy (LCRED) operation from primary line card to secondary line card triggers a missing QAM configuration problem.

Workaround:

Trigger another LCRED. The missing QAM issue is resolved.

CSCuc54049

Symptom:

Tracebacks are observed after replacing the secondary Cisco DS48-1G line card with a Cisco DS-48 line card.

Conditions:

This issue occurs when the secondary Cisco DS48-1G line card is configured to protect other DS48-1G line cards. After replacing the secondary DS48-1G with the Cisco DS48 line card, the tracebacks are observed.

Workaround:

There is no workaround. A Cisco DS-48 line card cannot protect the Cisco DS48-1G line cards.

CSCuc56647

Symptom:

Traceback occurs when a new remote RF profile is created.

Conditions:

This issue occurs when there are 16 RF profiles existing in the system. The maximum number of RF profile in the systems is 16, and that limit is reached.

Workaround:

Check the number of existing RF profiles before creating a new one.

CSCuc58675

Symptom:

A Qam-redundancy port configured as shutdown comes up in "UP" state instead of remaining in shutdown state.

Conditions:

This issue occurs if the secondary line card initially goes in active state following the reset of both the primary and secondary line cards.

Note This issue affects only the running-configuration and not the startup-configuration.

Workaround:

Manually configure the Qam-red port as shutdown.

CSCuc61424

Symptom:

On the Cisco RFGW-10 DS-384 line card, the DTI timing offset increases in time, when the offset should reduce it.

Conditions:

This issue occurs when the user inputs the DS-384 timing offset in the command line interface (CLI).

Workaround:

Do not use the timing offset for the Cisco RFGW-10 DS-384 line card.

Resolved Caveats for Cisco IOS-XE Release 3.2.0SQ

There are no resolved caveats for this release.

Important Notes

Fan Tray Failure Handling Enhancement

Effective from Cisco IOS-XE Release 3.2.3SQ, the Fan Tray Failure Handling Enhancement provides the warning system for fan failure events.

The failure of fan controllers is handled by the software in the following condition-action sets:

  • If less than 3 fans fail or the fan controller fails, the failure is set as partial failure.
  • If more than 2 fans fail, the failure is set as critical error.

For partial failure, an error message is logged in syslog and the show environment and show facility-alarm status commands display the error messages. Errors are logged once in syslog; they are not displayed continuously.

For critical error, an error message is logged in syslog and the Supervisor card starts the four-minute shutdown timer. The Supervisor card shuts down all line cards and the second Supervisor card at the four-minute timeout. The active Supervisor card continues to be operational.


Caution To avoid hardware damage, power down the chassis immediately after the four-minute shutdown.

Cisco DS-384 Line Card with P4080 CPU Revision 3

Effective with Cisco IOS-XE Release 3.2.3SQ, the Cisco RFGW-10 supports the new version of the Cisco DS-384 line card with P4080 CPU revision 3. The Version Identifier (VID) of the revised Cisco DS-384 line card is 2. Ensure that you run Cisco IOS-XE Release 3.2.3SQ or later releases, or Cisco IOS-XE Release 3.3.1SQ or later releases on the Supervisor engine 7-E to use the Cisco DS-384 VID 2 line card (with P4080 CPU revision 3).


Note If the Supervisor engine 7-E is running a release earlier than Cisco IOS-XE Release 3.2.3SQ, the Cisco RFGW-10 DS-384 VID 2 line card (with P4080 CPU revision 3) does not downgrade and hence, does not work.

Setting Platform Variables from IOS Environment

Effective with Cisco IOS-XE 3.2.3SQ, platform environment variables such as BootParam1 can be modified from the IOS Command Line Interface. This provides a convenient way to modify these variables, instead of using a directly connected console to modify them via the ROMMON.
