Caveats

Open Caveats for Cisco IOS Release 12.2(44)SQ

Caveat

Description

CSCsu27160

Symptoms: The GUI: HTTP CORE process may take a large percent of Supervisor
CPU at web page refresh.

Conditions: This issue occurs when a GUI web browser page is refreshed.

Workaround: There is no workaround.

CSCsv01988

Symptoms: The GUI “Summary” page does not display dual Supervisor interfaces
correctly. The GUI does not display information on the “Summary” page in the
SUP Input B/W or SUP Input Measurement sections.

Conditions: This issue occurs when redundant Supervisor cards are configured.

Workaround: There is no workaround.

CSCsw23043

Symptoms: Resetting one line card causes a momentary glitch on another line card.

Conditions: This issue occurs only when the

hw-module slot reset

command is

issued.

Workaround: Use the

cable linecard reset

command to reset a line card.

CSCsw26480

Symptoms: When un-muting an RF port, the RF power level tends to raises the
noise floor around the RF channels supported momentarily (for several hundreds
of milliseconds). There are no reported issues of cable modem performance, though
the impact is observed on a spectrum analyzer.

Conditions: This issue occurs during muting the RF port output power.

Workaround: There is no workaround.

CSCsw26789

Symptoms: The “DocsDevEvent” table does not function.

Conditions: When the MIB table is accessed, there is no data returned.

Workaround: There is no workaround.

Command RF
Output Power

DRFI requires support for a 8 dB range of commanded transmit power per channel
below the maximum power supported for the channel (maximum power - 8 dB).
The Cisco RFGW-10 is tested to a range of 10 dB of commanded power below the
maximum supported channel power.

Note

The Cisco RFGW-10 CLI allows a commanded RF power range 30 dB
lower than maximum supported channel power (maximum power - 30 dB).
However, a commanded power range below 10 dB of maximum power
supported is not calibrated and may not be accurate.

RF Gateway 10
Cablelabs DRFI
Compliance

The noise floor and spurious emissions of the Cisco RF Gateway 10 DS-48 line
card do not meet the requirements of the Cablelabs DRFI technical specification.
