MDS 9222i testing with looped port

is it possible to define a looped N-port on an MDS9222i (should just send the traffic back from receive to send)? if so, what command is needed? haven't found one so far but the data sheet tells me it should be possible.

thanks for any advice.

Performing Internal Loopback Tests

You can run manual loopback tests to identify hardware errors in the data path in the switching or services modules, and the control path in the supervisor modules. Internal loopback tests send and receive FC2 frames to/from the same ports and provide the round trip time taken in microseconds. These tests are available for Fibre Channel, IPS, and iSCSI interfaces.

Use the EXEC-level system health internal-loopback command to explicitly run this test on demand (when requested by the user) within ports for the entire module.

Use the EXEC-level system health internal-loopback command to explicitly run this test on demand (when requested by the user) within ports for the entire module and override the frame count configured on the switch.

switch# system health internal-loopback interface iscsi 8/1 frame-count 20

Use the EXEC-level system health internal-loopback command to explicitly run this test on demand (when requested by the user) within ports for the entire module and override the frame length configured on the switch.

switch# system health internal-loopback interface iscsi 8/1 frame-count 32
