Description
Symptoms: A difference of 65 to 70 units is observed in the timing offset received
by a modem.
Conditions: This issue occurs with Cisco IOS Release 12.2(50)SQ1 when
Cisco RFGW-10 is used for downstream by a modem registered on the CMTS.
This difference is observed between Cisco IOS Release 12.2(50)SQ1 and Cisco
IOS Release 12.2(50)SQ.
Workaround: Adjust the DSYNC setting on the CMTS router to compensate for
the difference in the timing offset.
Symptoms: Cable modem goes offline after the Cisco uBR10012 router, to which
the Cisco RFGW-10 is connected, performs a performance routing engine (PRE)
switchover.
Conditions: This issue occurs with large number of DEPI sessions. This has been
observed when control plane DEPI is in use and the secondary DEPI sessions are
configured.
Workaround: There is no workaround.
Symptoms: OIR of the active Supervisor resets the Cisco RFGW-10 DS-48 line
cards and drops the cable modems making them go offline.
Conditions: This issue occurs occasionally when the active Supervisor in slot 2 is
removed.
Workaround: There is no workaround.
Symptoms: The Cisco RFGW-10 DS-48 line card RF ports remain in admin
shutdown mode and Video/DEPI sessions remain IDLE.
Conditions: This issue occurs after line card image upgrade and reload.
Workaround: Execute "no shutdown" at QAM port level to enable all the
interfaces.
Symptoms: The standby Supervisor crashes.
Conditions: This issue occurs when the system is in stateful switchover (SSO)
mode and you copy commands from a running-config output to re-apply the
depi-tunnel configuration commands.
Workaround: Exit to the config mode before executing the depi-tunnel
configuration commands.
Symptoms: Standby Supervisor crashes when the DEPI remote learn mode change
is aborted.
Conditions: This issue occurs when you reject deletion of sessions at the CLI
confirmation prompt while changing the DEPI remote learn mode.
Workaround: Ensure that there are no DEPI sessions configured before changing
the remote learn mode on the QAM channel or accept the confirmation prompts.
Symptoms: Secondary DEPI sessions are not configurable with third-party Edge
QAM.
Conditions: This issue occurs when the CMTS and EQAM are configured for
DEPI Path redundancy (DPR).
Workaround: There is no workaround.
