CF-709
Cisco IOS Configuration Fundamentals Command Reference
July 2008
The following example displays details of a memory block overflow correction when the exception
memory ignore overflow global configuration command is configured:
Router# show memory overflow
Count Buffer Count Last corrected Crashinfo files
1 1 00:11:17 slot0:crashinfo_20030620-075755
Traceback 607D526C 608731A0 607172F8 607288E0 607A5688 607A566C
The report includes the amount of time since the last correction was made and the name of the file that
logged the memory block overflow details.
The show memory sram command displays the free SRAM memory blocks. For the Cisco 4000 router,
this command supports the high-speed static RAM memory pool to make it easier for you to debug or
diagnose problems with allocation or freeing of such memory.
The following is sample output from the show memory sram command:

The show memory summary command displays a summary of all memory pools and memory usage per
Alloc PC (address of the system call that allocated the block).
The following is a partial sample output from the show memory summary command. This output shows
the size, blocks, and bytes allocated. Bytes equal the size multiplied by the blocks. For a description of
the other fields, see Table 97 and Table 98.
