Cisco Systems 12000 series manual CF-709, Router# show memory overflow, Router# show memory sram

show memory

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:

Router# show memory sram

Address	Bytes Prev.		Next	Ref	PrevF	NextF	Alloc PC What
7AE0	38178	72F0	0	0	0	0	0
Total	38178

The following example of the show memory command used on the Cisco 4000 router includes information about SRAM memory and I/O memory:

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.
