Troubleshooting Line Card Module
It is important to decode the traceback message while filing DDTS. To decode a traceback symbol, files
of the corresponding image is required. A c7600 image has a set of symbol files like RP symbol file, SP
symbol file and a symbol file for each line card.
In general the messages before the traceback reveal the source of the traceback. So after determining
whether it is SP/RP/linecard traceback, the corresponding symbol file has to be chosen to decode it.
These are some commonly used symbol files:

Troubleshooting Image Reload Issues

Problem Solution
The following error message is displayed:
76k-eigrp-4#reload netboot
tftp://171.69.17.19/tftpboot/kapilk/nightly
/Fri/s72033-jsv-mz
Copying
tftp://171.69.17.19/tftpboot/kapilk/nightly

%Error opening sup-image:0 (Unknown error
0)
Ensure that you don't have a very large image
loaded on the 7600 to begin with, which may
cause resource problems. The solution is to load a
default image first and then do reload netboot.
