Core issue

The issue is documented in Cisco bug ID  CSCse29367.

When installing Security Device Manager (SDM) on Flash, it tries to communicate with the router, but it fails. This issue occurs consistently in all the platforms for the PI4 images, 12.4.9T, and 12.4.8.

The bug is seen in these router environments:

• 3845
  
  
• 3825
  
  
• 1760
  
  
• 2821
  
  
• 2801
  
  
• 7206

The issue is seen in these image:

• c3845-advsecurityk9-mz.124-7.24.T
  
  
• c3845-advsecurityk9-mz.124-7.11.PI4
  
  
• c1700-advsecurityk9-mz.124-7.24.T1
  
  
• c2800nm-advsecurityk9-mz.124-7.24.T1
  
  
• c2801-advsecurityk9-mz.124-7.11.PI4
  
  
• c7200-advsecurityk9-mz.124-7.11.PI4
  
  

Resolution

For a workaround, issue the ssh version 1 command on the router, as shown in this example:

Router(config)#ip ssh version 1
Router(config)#exit
Router#

As an alternative, run the installation wizard again, or install SDM on the PC.

Otherwise, downgrade the Cisco IOS Software to 12.4(6)T2ED.
