Cisco Cisco IOS Software Release 12.2(10)

All the caveats listed in 

 are open in Cisco IOS Release 12.2(10)DA1. This table lists only 

severity 1 and 2 caveats and select severity 3 caveats.

All open caveats in Cisco IOS Release 12.2(7)DA have been resolved.

8xDMT cards with interleaving delay configurations of 2000us and below have 
problems holding train and/or having less than expected upstream train rates.

Workaround: Avoid interleaving delay values of 2000us and below with 
8xDMT cards. Interleaving mode configurations should use 4000us delay or 
above. If lower delays are required, Fastpath mode can be used if supported by 
CPE being used.

The connection between the modem on a 4xDMT line card and the CPE is lost 
when an NI-2 redundancy switchover occurs.

Workaround: None.

When you copy a configuration file from a tftp server to the startup_config 
through snmp, ccCopyState (CISCO-CONFIG-COPY-MIB) will be in "running" 
state ever after. It will not change to "Failed" state.

The show startup command displays the following output:

%% Non-volatile configuration memory is being accessed, Try again

Workaround: Make sure that there is enough space available in the nvram before 
copying, using snmp or use cli.

Upgrades from Cisco IOS 12.1(7) DA to newer IOS images cause G.SHDSL 
ports to occasionally drop and retrain. The error is listed as LOSQ (Loss of Signal 
Quality) due to CRC errors detected or LOS when Loss of Frame Sync. is 
detected.

Workaround: Newer versions of G.SHDSL firmware have been adjusted to meet 
the ratified standards. This may require some fixed-rate loops to not hold train at 
the current configured rate used with Cisco IOS 12.1.(7)DA. Reducing the 
configured rate in some cases will resolve the issue. Random drops may still 
occur on some ports.

3db downstream margin configured ports on 8xDMT do not achieve max 
configured downstream rate on loops that should achieve max configured 
downstream rate.

Workaround: Use of DSL’s recommended 6db downstream margin will achieve 
max configured rate on loops expected to achieve max rate.
