Chapter 23 Troubleshooting SANTap
Initial Troubleshooting Checklist
Interface Restrictions
When enabled on a per-port basis, SANTap must be enabled on a group of four ports on an SSM. The
following restrictions apply:
•
The fewest number of interfaces that can be SANTap enabled is four.
•
The first interfaces in a group must be 1, 5, 9, 13, 17, 21, 25, or 29. (You can specify fc5 through
fc8, but not fc7 through fc10.)
•
The groups of four interfaces do not need to be consecutive. For example, you can specify fc1
through fc8 and fc17 through fc20.
Initial Troubleshooting Checklist
