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
Troubleshooting a SANTap problem involves gathering information about the configuration and
connectivity of the various SANTap components. Begin your troubleshooting activity as follows:

16 Prior to Cisco SAN-OS 3.1(2) with SSI 3.1(2m)
Sessions per SSM 1024 Cisco SAN-OS 3.0(2) with SSI 3.0(2j)
2048 Cisco SAN-OS 3.1(2b) with SSI 3.1(2m) and later
LUN ID address 32-bits Cisco SAN-OS 3.2
