12.3(13) - c2600-ik9o3s3-mz.123-13

IP/FW/IDS Plus IPSEC 3DES Basic

Problem Description

Customers using the IP/FW/IDS Plus IPSEC 3DES Basic feature set on Cisco2610/2611/2612/2613 will experience flash limitations when trying to load c2600-ik9o3s3-mz.123-13 image on a 16 MB flash SIMM. Cisco IOS® software version 12.3(13) is the first image where this issue will occur. Subsequent releases of this feature set will also encounter the same problem.

Customers will see the following when trying to load the image:

System flash directory: 
No files in System flash 
[0 bytes used, 16252924 available, 16252924 total] 
16384K bytes of processor board System flash (Read/Write) 

Loading c2600-ik9o3s3-mz.123-13.bin from xxx.xx.xxx.xxx (via Ethernet0/0): ! 
%Error copying tftp://xxx.xx.xxx.xxx/c2600-ik9o3s3-mz.123-13.bin (Not enough space on device) 

The maximum default for the 2610, 2611, 2612, 2613 is a 16MB flash SIMM.

The maximum default for the 2620 and 2621 is a 32MB flash SIMM. This issue is seen when using the 16MB flash SIMM only.

Background

Refer to Product Bulletin No. 1975 for a background on this issue.

As more functionality is added to the current mix of Cisco platforms, additional memory requirements are needed to run these images. This has affected some platforms such as the Cisco 261x series since these platforms only support a maximum of 16MB of flash. In order to address these platforms with limited memory capacity and provide a migration through 12.3 mainline, a number of "Basic" images have been created to address this need. Due to these memory constraints, these platforms will not be supported in Cisco IOS software versions 12.3T and later. These new images are based on a reduced feature set and/or do not include new functionality in the same release as other new non "Basic" images.

Problem Symptoms

The following will be exhibited when trying to load c2600-ik9o3s3-mz.123-13.bin image onto 2610/2611/2612/2613/2620/2621 routers from default 16MB Flash:

System flash directory: 
No files in System flash 
[0 bytes used, 16252924 available, 16252924 total] 
16384K bytes of processor board System flash (Read/Write) 

Loading c2600-ik9o3s3-mz.123-13.bin from XXX.XX.XXX.XXX (via Ethernet0/0): ! 
%Error copying tftp://XXX.XX.XXX.XXX/c2600-ik9o3s3-mz.123-13.bin (Not enough 
space on device) 

Workaround/Solution

For the 2610/2611/2612/2613/2620/2621 using the 16MB flash SIMM:

Workaround is to issued the following command for the flash directory:

erase /no-squeeze-reserve-space flash: 

Example:

c261X-router#erase /no-squeeze-reserve-space flash: 
Erasing the flash filesystem will remove all files! Continue? [confirm] 
Erasing device... 
eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee 
...erased 
Erase of flash: complete 
c261X-router#dir 
Directory of flash:/ 


No files in directory 


16777212 bytes total (16777212 bytes free) 

There is no solution to this issue for the 2610/2611/2612/2613/2620/2621 routers, only the workaround stated above.

Refer to Product Bulletin No. 1975.

For the 2620 and 2621 using the 16MB flash SIMM, the workaround above will work, or the 32MB flash can be purchased to upgrade the router to 32 MB flash.
