Step 3
If the Link Status is down, make sure the sensing port is connected properly:
•
Make sure the sensing port is connected properly on the appliance.
•
Make sure the sensing port is connected to the correct SPAN or VACL capture port on IDSM2.
Step 4
Verify the interface configuration:
•
Make sure you have the interfaces configured properly.
•
Verify the SPAN and VACL capture port configuration on the Cisco switch.
Refer to your switch documentation for the procedure.
Step 5
Verify again that the interfaces are up and that the packet count is increasing.
