You can test the integrity of any existing connection that is nondisruptive to user traffic. The operation
is similar to the tstcon command. For more information on the tstcon command, refer to the Cisco WAN

Step 7 Enter the number of connections that you want to retrieve in the Connection Count to be retrieved
field. To retrieve all the connections, enter *.
