[c-nsp] Cisco UBR 924 w/ comcast - Help?

[Kenny Long]

Group,

There have been a couple of good suggestions and some progress on this.
Here is my latest findings and my suspect.

In the debug linked to in the Original Post, the TFTP of the
d10_walledgarden config failes although I can download it manually from the
router, during the brief period of time where the int is up/up.

I did a debug tftp packet and events and I get this at the time of that
failure

00:09:23: TFTP: Sending error 3 Buffer overflow

00:09:23:    563.954 CMAC_LOG_CONFIG_FILE_PROCESS_COMPLETE

 Notice the error 3 Buffer overflow, any ideas on how to fix that one?  I
checked show buffers
and their was failures on the small buffers, I bumped those up to the point
where I dont get failures but that didnt seem to affect this.  Is that even
the buffer that the debug speaks of?

Thanks for the help.
