Hello John,

This is likely a known issue of incompatibility with Cisco IOS 12.4 or newer.

To verify this, would you send 'Trace Options' of your attempted connection using the instructions below?

Also, when you contact us via e-mail, please provide your serial number so I can check your upgrade eligibility.

To enable trace options output:
  • First, open SecureCRT's main "File" pull-down menu and select "Trace Options". If you open the "File" pull down menu again you should see a checkmark next to "Trace Options", indicating that troubleshooting output is now enabled.
  • Next, connect to the remote machine. With trace options enabled, you will notice debugging information displayed in the terminal window that isn't normally there by default when SecureCRT is attempting to establish a connection, and at certain times throughout the lifetime of the connection.
  • Once the problem occurs, please right-click inside the terminal window and choose "Select All", then right-click again and choose "Copy" to transfer the information to the Windows clipboard.
  • Finally, open a text editor like 'Notepad', paste the information from the Windows clipboard into the editor program, and save it as a text file.
Since trace options can contain sensitive information, feel free to send it as an attachment via e-mail to Please reference "Attn Brenda - Forum Thread #5508" in the subject line.
