Unresolved Caveats for Release 12.1(5)YC1
This section describes possibly unexpected behavior, specific to the Cisco 827 and 827-4V routers, by
Release 12.1(5)YC1.
CSCdt47054
When the router is configured to an ATM PVC with PPPoE encapsulation, it will crash when the ATM
PVC is removed in a subsequent configuration while the PPPoE session is still active.
CSCdt61879
When the configuration file URL in the ImageTable script is changed to point to a different, new
configuration file and the router is reloaded, the previous configuration file is downloaded, rather than
the new one. The problem has been traced to the cache in the PE, which retains the previous URL of the
configuration file and sends that URL to the tftp server. The workaround is to clear the PE cache before
reloading the router. This forces the PE to reload its cache with the latest information from the
ImageTable script.
CSCdt61928
The router will crash when executing cl or de commands in exec mode. The workaround is to expand
these commands to at least cle and deb.
CSCdt61929
A zero byte configuration file will cause the router to operate in a loop and repeatedly download the
configuration file.
