Step 4 Verify that the interface status and line protocol are up. If they are not, check the interface configuration
and connection.
Step 5 Verify that the input and output counters are incrementing. Check the display numerous times to verify
the interface is receiving and sending frames.
Step 6 Enter the show atm vc interface command to verify the status of the ATM router module virtual
connection.
