Troubleshooting an IPSec tunnel

If problems continue, then ISAKMP and IPSec debugging modes may be used. Turning on all debug

modes is rather verbose, so we recommend basic ISAKMP debugging initially. Capture the following

debugging:

ena isakmp debug=state

• You can also use the command:

ena isakmp debug=trace

• Attempt connection from your IPSec remote PC client

• To end your debugging trace use the command:

dis isakmp debug=all

If the basic ISAKMP debugging modes does not reveal a problem to you, then all debugging modes

should be enabled and captured to a text file and sent to your support centre. Use the commands

• ena ipsec poli=tunnel debug=all

• ena isakmp debug

Also capture sh log to show ISAKMP log entries (as mentioned above), capture sh fire event

and sh debug. Forward all this debugging to your local technical support for analysis. Your local

support centre also have access to advanced support centres if necessary. Allied Telesyn offers

technical assistance in partnership with our authorised distributors and resellers. For technical
